Tested: PCDIMM can be hot removed after stress-ng workload

This picks upstream commit f183663901f2 ("mm: consider non-anon swap cache
folios in folio_expected_ref_count()"), which corrects the reference count
for non-anon swap cache folios. Otherwise, the hot added PCDIMM can't be
hot removed in an aarch64 guest after the excercise with 'stress-ng'.

CVE: CVE-2026-53062
Tested: Reproducer and dm cache tests
Upstream Status: kernel/git/torvalds/linux.git

commit d3f0a606b9f278ece8a0df626ded9c4044071235
Author: Guangshuo Li <lgs201920130244@gmail.com>
Date:   Fri May 29 23:57:45 2026 +0800

    dm cache policy smq: check allocation under invalidate lock

    commit 2d1f7b65f5de ("dm cache policy smq: fix missing locks in
    invalidating cache blocks") added mq->lock around the destructive part of
    smq_invalidate_mapping(), but left the e->allocated check outside the
    critical section.

    That leaves a check-then-act race. Two concurrent invalidators can both
    observe e->allocated as true before either of them takes mq->lock. The
    first invalidator that acquires the lock removes the entry from the
    queues and hash table and then calls free_entry(), which clears
    e->allocated and puts the entry back on the free list. The second
    invalidator can then acquire mq->lock and continue with the stale result
    of the unlocked check.

    This can corrupt the SMQ queues or hash table by deleting an entry that
    is no longer on those structures. It can also hit the allocation check in
    free_entry() when the same entry is freed again.

    Move the allocation check under mq->lock so the predicate and the
    destructive operations are serialized by the same lock.

CKI KWF Bot b3607ff92b Merge: CVE-2026-64277: Input: synaptics-rmi4 - bound the F3A keymap to the GPIO count 
MR: https://gitlab.com/redhat/centos-stream/src/kernel/centos-stream-10/-/merge_requests/3170

JIRA: https://redhat.atlassian.net/browse/RHEL-231458
CVE: CVE-2026-64277

Backported from tree(s): linux

```
Input: synaptics-rmi4 - bound the F3A keymap to the GPIO count

rmi_f3a_initialize() takes the GPIO count from the device query register
(f3a->gpio_count = buf & RMI_F3A_GPIO_COUNT, range 0..127).
rmi_f3a_map_gpios() then allocates gpio_key_map with
min(gpio_count, TRACKSTICK_RANGE_END) == at most 6 entries, but
rmi_f3a_attention() iterates the full gpio_count and dereferences
gpio_key_map[i], and input->keycodemax is set to the full gpio_count
while input->keycode points at the 6-entry allocation.

A device that reports gpio_count > 6 therefore causes an out-of-bounds
read of gpio_key_map[] on every attention interrupt, and out-of-bounds
accesses through the input core's default keymap ioctls: EVIOCGKEYCODE
reads past the buffer (leaking adjacent slab memory to user space) and
EVIOCSKEYCODE writes a caller-controlled value past it, for any process
able to open the evdev node, since input_default_getkeycode() and
input_default_setkeycode() only bound the index against keycodemax.

Size the keymap for the full gpio_count. The mapping loop is unchanged:
it still assigns only the first min(gpio_count, TRACKSTICK_RANGE_END)
entries; the remaining slots stay KEY_RESERVED (devm_kcalloc zero-fills)
and are skipped when reporting.

This MR brings PMU support for Intel Diamond Rapids and Nova Lake models.
The features are split into multiple JIRA tickets, but make sense to merge
together in one batch. This brings uncore, core and cstate support plus
some fixes and extensions required by the mentioned platforms.

Omitted-fix: d9b40d7262a2 ("selftests/x86: Add selftests include path for kselftest.h after centralization")

This series backports most of relevant cgroup selftests commits in linux
mainline and mm-stable maintainer tree to reduce the failure rate of
the cgroup selftests. This commits do not fix all the test failures but
still many of them should be gone.

By running the cgroup selftests 100 times on an arm64 and x86-64
systems, the table below shows the number of test failures before and
after applying the patches.

	x86-64
	======
	Test					  Before	After
	----					  ------	-----
	test_cpucg_nested_weight_overprovisioned    62		 66
	test_cpucg_stats			    50		 50
	test_cpucg_weight_overprovisioned	    62		 66
	test_memcg_low				   100		  6
	test_memcg_min				    29		  1
	test_memcg_sock				   100		  0
	test_zswap_writeback_disabled		   100		  0
	test_zswap_writeback_enabled		   100		  0
	test_zswapin				   100		  0

	----					  ------	-----
	test_cpucg_max				    39		 44
	test_cpucg_max_nested			    25		 23
	test_cpucg_nested_weight_overprovisioned    57		 58
	test_cpucg_nested_weight_underprovisioned    2		  3
	test_cpucg_nice				    95		 79

	test_zswap_writeback_enabled		   100		  0
	test_zswapin				   100		  0

The test_zswap failures are all gone and some of the test_memcontrol
failures are gone. However this MR has no real impact on test_cpu and
test_freezer failures.

CKI KWF Bot f3bb824a4e Merge: redhat/configs: automotive: disable CONFIG_MD 
MR: https://gitlab.com/redhat/centos-stream/src/kernel/centos-stream-10/-/merge_requests/3256

## Summary of Changes

CONFIG_MD=y has no effect in automotive; the subsystem's Makefile
doesn't have any obj-y additions, and the only Kconfigs enabled in
automotive that are used in the subsystem's Makefile are:

        $ git grep -Pho '\$\(CONFIG_[^)]+\)' drivers/md/Makefile |
                sort -u |
                tr -d '$()' |
                xargs -I{} grep -F "{}=" redhat/configs/kernel-*-automotive*.config
        redhat/configs/kernel-6.12.0-aarch64-automotive.config:CONFIG_BLK_DEV_ZONED=y
        redhat/configs/kernel-6.12.0-aarch64-automotive-debug.config:CONFIG_BLK_DEV_ZONED=y
        redhat/configs/kernel-6.12.0-x86_64-automotive.config:CONFIG_BLK_DEV_ZONED=y
        redhat/configs/kernel-6.12.0-x86_64-automotive-debug.config:CONFIG_BLK_DEV_ZONED=y
        redhat/configs/kernel-6.12.0-aarch64-automotive.config:CONFIG_IMA=y
        redhat/configs/kernel-6.12.0-aarch64-automotive-debug.config:CONFIG_IMA=y
        redhat/configs/kernel-6.12.0-x86_64-automotive.config:CONFIG_IMA=y
        redhat/configs/kernel-6.12.0-x86_64-automotive-debug.config:CONFIG_IMA=y

These Kconfigs are only used to modify dm-mod.o, which isn't built in
automotive kernels since it depends on CONFIG_BLK_DEV_DM.

CONFIG_MD is also the only MD-related Kconfig that's enabled in
automotive:

        $ grep -P 'CONFIG_(.+_)?MD[_=]' redhat/configs/kernel-*-automotive*.config
        redhat/configs/kernel-6.12.0-aarch64-automotive.config:CONFIG_MD=y
        redhat/configs/kernel-6.12.0-aarch64-automotive-debug.config:CONFIG_MD=y
        redhat/configs/kernel-6.12.0-x86_64-automotive.config:CONFIG_MD=y
        redhat/configs/kernel-6.12.0-x86_64-automotive-debug.config:CONFIG_MD=y

Since the Kconfig is essentially a no-op, disable it in automotive
kernels.

MR: https://gitlab.com/redhat/centos-stream/src/kernel/centos-stream-10/-/merge_requests/3204

JIRA: https://redhat.atlassian.net/browse/RHEL-212122

xe OA and EU-stall paths open-code a partial copy of the system-wide
perf CPU-event permission check:

    if (xe_observation_paranoid && !perfmon_capable())
            return -EACCES;

This open-coded check skips two things perf_allow_cpu() handles: the
graduated kernel.perf_event_paranoid policy that an administrator
may have tuned, and the security_perf_event_open() LSM hook.

Introduce xe_observation_paranoid_check() to wrap perf_allow_cpu(),
and convert the open-coded sites in xe_oa.c and xe_eu_stall.c. The
dev.xe.observation_paranoid sysctl still acts as an escape hatch
when cleared.

xe observation now consults kernel.perf_event_paranoid and the LSM
perf hook on every open. Sites that have already configured an LSM
perf policy or tuned the paranoid sysctl will see those settings
extend to xe.

CVE: CVE-2026-63952

```
memfd: deny writeable mappings when implying SEAL_WRITE

When SEAL_EXEC is added, SEAL_WRITE is implied to make W^X.  But the
implied seal is set after the check that makes sure the memfd can not have
any writable mappings.  This means one can use SEAL_EXEC to apply
SEAL_WRITE while having writeable mappings.

This breaks the contract that SEAL_WRITE provides and can be used by an
attacker to pass a memfd that appears to be write sealed but can still be
modified arbitrarily.

Fix this by adding the implied seals before the call for
mapping_deny_writable() is done.

commit 9e6bf146b55999a095bb14f73a843942456d1adc
Author: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
Date:   Tue Apr 21 15:16:33 2026 +0200

    ipv6: rpl: reserve mac_len headroom when recompressed SRH grows

    ipv6_rpl_srh_rcv() decompresses an RFC 6554 Source Routing Header, swaps
    the next segment into ipv6_hdr->daddr, recompresses, then pulls the old
    header and pushes the new one plus the IPv6 header back.  The
    recompressed header can be larger than the received one when the swap
    reduces the common-prefix length the segments share with daddr (CmprI=0,
    CmprE>0, seg[0][0] != daddr[0] gives the maximum +8 bytes).

    pskb_expand_head() was gated on segments_left == 0, so on earlier
    segments the push consumed unchecked headroom.  Once skb_push() leaves
    fewer than skb->mac_len bytes in front of data,
    skb_mac_header_rebuild()'s call to:

            skb_set_mac_header(skb, -skb->mac_len);

    will store (data - head) - mac_len into the u16 mac_header field, which
    wraps to ~65530, and the following memmove() writes mac_len bytes ~64KiB
    past skb->head.

    A single AF_INET6/SOCK_RAW/IPV6_HDRINCL packet over lo with a two
    segment type-3 SRH (CmprI=0, CmprE=15) reaches headroom 8 after one
    pass; KASAN reports a 14-byte OOB write in ipv6_rthdr_rcv.

    Fix this by expanding the head whenever the remaining room is less than
    the push size plus mac_len, and request that much extra so the rebuilt
    MAC header fits afterwards.

    net/ipv6: ioam6: prevent schema length wraparound in trace fill

    ioam6_fill_trace_data() stores the schema contribution to the trace
    length in a u8. With bit 22 enabled and the largest schema payload,
    sclen becomes 1 + 1020 / 4, wraps from 256 to 0, and bypasses the
    remaining-space check. __ioam6_fill_trace_data() then positions the
    write cursor without reserving the schema area but still copies the
    4-byte schema header and the full schema payload, overrunning the trace
    buffer.

    Keep sclen in an unsigned int so the remaining-space check and the write
    cursor calculation both see the full schema length.

JIRA: https://redhat.atlassian.net/browse/RHEL-159116
Upstream Status: RHEL only.

This patch was backported a bit overzealously as part of a recent
ext4 upstream syncup. The requisite changes to connect the crc32c
library to the arch optimizations referred to in the original commit
do not exist in CS10, which means this actually causes a performance
degradation on high performance storage. Since the library changes
are unplanned, back out the change in ext4 to restore original
performance.

JIRA: https://redhat.atlassian.net/browse/RHEL-214116

commit 7441d6348c70738e9ed307510db171c7a9b3f4bf
Author: Aboorva Devarajan <aboorvad@linux.ibm.com>
Date: Thu, 9 Jul 2026 01:49:54 +0530

    snapshot_page() currently reads __page_2 after checking nr_pages > 1, but
    it should only do so when nr_pages > 2.

    If an order-1 folio is allocated at the end of a vmemmap section,
    __page_2 will not exist and reading it will cause a fault.

    During DLPAR memory remove on a 22 TB ppc64le LPAR, snapshot_page() oopsed
    on the page isolation path while reading an order-1 folio's __page_2 from
    an adjacent absent section (unmapped vmemmap).

    Fix this to avoid reading memmap that doesn't exist (e.g., a vmemmap
    hole).

JIRA: https://redhat.atlassian.net/browse/RHEL-153139

Testing: Ran
```

net/tls splice tests currently fail on 64k page kernel because of missing upstream commit:
  3e52f56875c6 ("selftests: tls: size splice_short pipe by page size")

This MR brings the net/tls selftest up to v7.2-rc1, which is the above commits plus two freebies.

========
commit 5948aaf64f81f217a25dcc2bf6c0779bca19566c
Author: Lee Jia Jie <jiajie.lee@starlabs.sg>
Date: Thu Jul 9 21:56:19 2026 +0800

description
===========
map_range() reads rb->aux_pages[], rb->aux_nr_pages and rb->aux_pgoff via
perf_mmap_to_page() while holding only event->mmap_mutex. Those fields are
serialized by rb->aux_mutex, and mmap_mutex is per event.

Thus, two events sharing one rb via PERF_EVENT_IOC_SET_OUTPUT can race
rb_alloc_aux() with map_range(), leading to a page-UAF scenario as follows:

  CPU 0                           CPU 1
  =====                           =====
  rb_alloc_aux()                  map_range()
  [1]: allocate rb->aux_pages[0]
  [2]: rb->aux_nr_pages++
                                  [3]: perf_mmap_to_page()
                                         returns rb->aux_pages[0]
                                  [4]: map it as VM_PFNMAP
  [5]: rb->aux_pgoff = 1

  munmap the page
  [6]: free rb->aux_pages[0]

Pages mapped as VM_PFNMAP have no refcount protection, so CPU 1 holds a
mapping to a freed physical frame.

Fix this by taking rb->aux_mutex across the page walk in map_range().

The scope is limited to SoC-level DTSI updates for NXP/Freescale i.MX8 and TI K3/AM62 platforms. Board-specific DTS churn, defconfig-only changes, ARM64 core changes, MM/sysreg changes, crypto/FPSIMD changes, and unrelated dependency series were intentionally excluded to keep the MR focused and reviewable.

    A second splat follows right after, from timer_setup() finding that same
    timer already queued:

      ODEBUG: init active (active state 0) object: (____ptrval____) object type: timer_list hint: stub_timer+0x0/0x10

    This is happening because CMCI storm detection is trying to modify the timer
    before latter was properly set up.

    Set up the timer first. __mcheck_cpu_setup_timer() only calls timer_setup(),
    and depends on neither the generic nor the vendor init.

# Merge Request Required Information

## Summary of Changes

JIRA: https://redhat.atlassian.net/browse/RHEL-231666

CVE: CVE-2026-63886

In the Linux kernel, the following vulnerability has been resolved:

scsi: target: iscsi: Validate CHAP_R length before base64 decode

chap_server_compute_hash() allocates client_digest as
kzalloc(chap->digest_size) and then, for BASE64-encoded responses,
passes chap_r directly to chap_base64_decode() without checking whether
the input length could produce more than digest_size bytes of output.

chap_base64_decode() writes to the destination unconditionally as long
as there is input to consume. With MAX_RESPONSE_LENGTH set to 128 and
the "0b" prefix stripped by extract_param(), up to 127 base64 characters
can reach the decoder. 127 characters decode to 95 bytes. For SHA-256
(digest_size=32) this overflows client_digest by 63 bytes; for MD5
(digest_size=16) the overflow is 79 bytes.

The length check at line 344 fires after the write has already happened.

The HEX branch in the same switch statement already validates the length
up front. Apply the same approach to the BASE64 branch: strip trailing
base64 padding characters, then reject any input whose data length
exceeds DIV_ROUND_UP(digest_size * 4, 3) before calling the decoder.

Stripping trailing '=' before the comparison handles both padded and
unpadded encodings. chap_base64_decode() already returns early on '=',
so the full original string is still passed to the decoder unchanged.

The mutual CHAP path decodes CHAP_C into initiatorchg_binhex, which is
kzalloc(CHAP_CHALLENGE_STR_LEN). extract_param() caps initiatorchg at
CHAP_CHALLENGE_STR_LEN characters, so at most CHAP_CHALLENGE_STR_LEN-1
base64 characters reach the decoder. The maximum decoded size,
DIV_ROUND_UP((CHAP_CHALLENGE_STR_LEN-1) * 3, 4), is less than
CHAP_CHALLENGE_STR_LEN, so no overflow is possible there. A comment is
added at the call site to document this.

    thermal: core: Fix thermal zone device registration error path

    If thermal_zone_device_register_with_trips() fails after registering
    a thermal zone device, it needs to wait for the tz->removal completion
    like thermal_zone_device_unregister(), in case user space has managed
    to take a reference to the thermal zone device's kobject, in which case
    thermal_release() may not be called by the error path itself and tz may
    be freed prematurely.

    Add the missing wait_for_completion() call to the thermal zone device
    registration error path.

JIRA: https://issues.redhat.com/browse/RHEL-176084

NVIDIA Olympus has SMT cores that share `PMCCNTR_EL0`. This results in the counter incrementing even during a WFI/WFE if the sibling is not idle which is unexpected. This patch avoids using `PMCCNTR_EL0` on the platform.

CKI KWF Bot 22ca799912 Merge: cpuidle: resolve a potential performance degradation 
MR: https://gitlab.com/redhat/centos-stream/src/kernel/centos-stream-10/-/merge_requests/3221

RESOLVES: RHEL-222582
JIRA: https://redhat.atlassian.net/browse/RHEL-222582
Upstream Status: RHEL-Only

This reverts commit 9216f15650.

Commit 9216f15650 reverted a
commit that caused a performance regression on some Intel
Jasper Lake systems. Reverting that commit caused a different
performance regression on some other systems. On balance,
we would prefer that those other systems have better performance
even if some Jasper Lake systems suffer worse performance.

MR: https://gitlab.com/redhat/centos-stream/src/kernel/centos-stream-10/-/merge_requests/3074

JIRA: https://redhat.atlassian.net/browse/RHEL-224534

```
vhost: reset the vring metadata cache on vring reconfiguration

vq->meta_iotlb[] caches the vhost_iotlb_map that backs each vring
metadata region, and iotlb_access_ok() returns early on a cache hit,
taking the hit as proof that the region has already been validated:

	if (vhost_vq_meta_fetch(vq, addr, len, type))
		return true;

The cache is reset on VHOST_IOTLB_UPDATE and VHOST_IOTLB_INVALIDATE, on
device IOTLB (re)initialisation and on vq reset, but not when
VHOST_SET_VRING_ADDR replaces vq->desc, vq->avail and vq->used, nor when
VHOST_SET_VRING_NUM changes the region sizes.

With a device IOTLB attached both ioctls are accepted while the vq is
live, and neither validates the addresses at ioctl time: vq_access_ok()
and vq_log_used_access_ok() return true early because the addresses are
GIOVAs, deferring validation to prefetch time.  Once the cache has been
populated that deferred validation no longer runs -- vq_meta_prefetch()
hits the stale entry and returns true -- and vhost_vq_meta_fetch() keeps
translating through the old mapping as

	map->addr + addr - map->start

for an address the mapping no longer covers.  vhost_copy_to_user() and
vhost_copy_from_user() consume the result with __copy_to_user() and
__copy_from_user(), which do not check it either, so a subsequent used
ring update or descriptor fetch accesses memory outside the region the
IOTLB actually maps.

Reset the metadata cache whenever the vring is reconfigured, so the new
addresses are pushed back through iotlb_access_ok()'s slow path.

iio: event: Fix event FIFO reset race

`iio_event_getfd()` creates the event file descriptor with
`anon_inode_getfd()`, which allocates a new fd, creates the anonymous
file and installs it in the process fd table before returning to the
caller.

The IIO code resets the event FIFO after `anon_inode_getfd()` has returned,
but before `IIO_GET_EVENT_FD_IOCTL` has copied the fd number to userspace.
But since fd tables are shared between threads, another thread can guess
the newly allocated fd number and issue a `read()` on it as soon as the fd
has been installed.

This means the `kfifo_to_user()` in `iio_event_chrdev_read()` can run in
parallel with the `kfifo_reset_out()` in `iio_event_getfd()`.

The kfifo documentation says that `kfifo_reset_out()` is only safe when it
is called from the reader thread and there is only one concurrent reader.
Otherwise it is dangerous and must be handled in the same way as
`kfifo_reset()`.

If that happens, `kfifo_to_user()` can advance the FIFO `out` index based
on state from before the reset, after the reset has already moved the `out`
index to the current `in` index. That can leave the FIFO with an `out`
index past the `in` index. A later `read()` can then see an underflowed
FIFO length and copy more data than the event FIFO buffer contains. This
can result in an out-of-bounds read and leak adjacent kernel memory to
userspace.

Move the FIFO reset before `anon_inode_getfd()`. At that point the event fd is
marked busy, but the new fd has not been installed yet, so userspace cannot
access it while the FIFO is reset.

net: openvswitch: reject oversized nested action attrs

Open vSwitch stores generated flow actions as nlattrs, whose nla_len
field is u16. Commit a1e64addf3ff ("net: openvswitch: remove
misbehaving actions length check") allowed the total sw_flow_actions
stream to grow beyond 64 KiB, which is valid, but also removed the last
guard preventing a generated nested action attribute from exceeding
U16_MAX.

An oversized generated container can thus be closed with a truncated
nla_len. A later dump or teardown then walks a structurally different
stream than the one that was validated. In particular, an oversized
nested CLONE/CT action may cause subsequent bytes in the generated
stream to be interpreted as independent actions.

Keep the larger total-action-stream behavior, but make nested action
close reject generated containers that do not fit in nla_len, and return
the error through all callers. For recursive SAMPLE, CLONE, DEC_TTL, and
CHECK_PKT_LEN builders, trim resource-owning action-list tails in reverse
construction order before discarding failed wrappers, so resources copied
into the rejected tails are released before the wrappers are removed.

Most failed outer wrappers are discarded by truncating actions_len after
child resources have been released. CHECK_PKT_LEN also trims its parent
after branch resources are gone. SET/TUNNEL close failures unwind their
known tun_dst ownership directly, and SET_TO_MASKED has no external
ownership and truncates on close failure.

    pinctrl-amd: Don't clear S4 wake bits at probe

    commit 6bc3462a0f ("pinctrl: amd: Mask wake bits on probe again")
    introduced a regression where Wake-on-LAN no longer works after suspend
    or shutdown on some AMD platforms.

    Firmware-programmed S4 wake bits for devices like PCIe NICs using PCI
    PME are cleared at probe, but nothing restores them. Unlike S0i3/S3 wake
    sources that use enable_irq_wake() -> amd_gpio_irq_set_wake(), PCIe PME
    does not use GPIO IRQ infrastructure and relies on firmware configuration.

    The original intent of commit 6bc3462a0f ("pinctrl: amd: Mask wake
    bits on probe again") was to clear spurious wake bits left by firmware
    to prevent unwanted wakeups. However, S4 wake bits are used for
    hardware-level wake sources like WoL that bypass the kernel's IRQ wake
    API.

    Fix by preserving S4 wake bits at probe and only clearing S0i3/S3 bits:
    - Firmware-configured S4 wake sources (WoL) continue working
    - Kernel maintains control of S3/S0i3 wake policy via set_wake()
    - S3-only wake sources work correctly per commit f31f33dbb3ba ("pinctrl:
      amd: Take suspend type into consideration which pins are non-wake")

    The trade-off is that firmware-programmed spurious S4 wake bits remain
    set, but this is less problematic than breaking WoL.

MR: https://gitlab.com/redhat/centos-stream/src/kernel/centos-stream-10/-/merge_requests/3007

JIRA: https://redhat.atlassian.net/browse/RHEL-218195

Fix a deadlock introduced by https://gitlab.com/redhat/centos-stream/src/kernel/centos-stream-10/-/commit/83634e21c064.

Since queue operations require holding a lock, the operations inside should use the locked variant.

[mschmidt] The commit "net: hold netdev instance lock during queue operations" was already backported in RHEL 10.2 as commit cd0f008574. At the time, the netif_napi_set_irq() call in gve_add_napi() wasn't present yet, so the change was omitted. RHEL-178516 later updated the gve driver without taking the netdev locking change fully into account. Younes is now backporting the missing change.

CVE: CVE-2026-45991

Backport of upstream commit 08841b06fa64d8edbd1a21ca6e613420c90cc4b8.

Fixes heap OOB write in handle_partition_descriptor() triggered by crafted UDF images with repeated partition descriptors.

Manual backport - trivial context conflict: upstream uses kzalloc_objs(), cs10 uses kcalloc().The allocation call itself is not modified by the fix.

    cpufreq: intel_pstate: Set non-turbo capacity to HWP_GUARANTEED_PERF()

    Setting cpu->capacity_perf to cpu->pstate.max_pstate_physical in the
    "no turbo" case is inconsistent with what happens elsewhere in the
    driver and causes arch_scale_cpu_capacity() to be incorrect.  It also
    skews arch_scale_freq_capacity() which ends up differing from 1024 for
    the guaranteed P-state.

    Address that by setting capacity_perf to HWP_GUARANTEED_PERF() in the
    "no turbo" case.

    thermal: intel: Fix dangling resources on thermal_throttle_online() failure

    The function thermal_throttle_add_dev() may fail and abort a CPU hotplug
    online operation. Since the failure occurs within the online callback,
    thermal_throttle_online(), the CPU hotplug framework does not invoke the
    corresponding offline callback. As a result, the hardware and software
    resources set up during the failed operation are not torn down.

    Since only thermal_throttle_add_dev() can fail, call it before setting up
    the rest of the resources.

    platform/x86/intel-uncore-freq: Fix current_freq_khz after CPU hotplug

    When the last CPU of a legacy uncore die goes offline,
    uncore_freq_remove_die_entry() clears control_cpu. During CPU hotplug
    re-add, uncore_freq_add_entry() still populates sysfs attributes before
    assigning the new control CPU. As a result, the current frequency read
    returns -ENXIO and current_freq_khz is omitted from the recreated sysfs
    group.

    Assign control_cpu before the initial read paths and before
    create_attr_group() so sysfs recreation uses the new online CPU. If
    sysfs creation fails, restore control_cpu to -1 to keep the error path
    state consistent.

Omitted-fix: fa188edc671d ("linux/bitfield.h: replace __auto_type with auto")

This MR backports commit a734d9fca84e ("futex: Optimize futex hash
bucket access patterns") to improve the futex hashing performance as
measured by the "perf bench futex hash" benchmark to a level comparable
with that of RHEL 9.7.

Patch 1 is a dependency that is used to simplify the backport and patch
2 is its fix patch.

When running the “perf bench futex hash” benchmark on a 2-sock 96-thread
CascadeLake test system, the test results before and after the patch are
as follows:
```

```
commit 0d0eb186421d0886ac466008235f6d9eedaf918e
Author: Harshita V Rajput <harshitha.vr@chelsio.com>
Date:   Tue Oct 28 13:22:55 2025 +0530

    cxgb4: flower: add support for fragmentation

    This patch adds support for matching fragmented packets in tc flower
    filters.

    Previously, commit 93a8540aac ("cxgb4: flower: validate control flags")
    added a check using flow_rule_match_has_control_flags() to reject
    any rules with control flags, as the driver did not support
    fragmentation at that time.

    Now, with this patch, support for FLOW_DIS_IS_FRAGMENT is added:
    - The driver checks for control flags using
      flow_rule_is_supp_control_flags(), as recommended in
      commit d11e631194 ("flow_offload: add control flag checking helpers").
    - If the fragmentation flag is present, the driver sets `fs->val.frag` and
      `fs->mask.frag` accordingly in the filter specification.

    Since fragmentation is now supported, the earlier check that rejected all
    control flags (flow_rule_match_has_control_flags()) has been removed.

MR: https://gitlab.com/redhat/centos-stream/src/kernel/centos-stream-10/-/merge_requests/3042

## Summary of Changes

Enable `KASAN_INLINE` instead of `KASAN_OUTLINE` to improve automotive debug kernel performance. This allows debug kernels to boot on the NXP S32G-VNP-RDB3 without running into timing issues, such as timeouts while waiting for rootfs to mount, sleeps taking longer than expected, and kernel timestamps going backwards.
