overflow: Add struct_size_t() helper
While struct_size() is normally used in situations where the structure
type already has a pointer instance, there are places where no variable
is available. In the past, this has been worked around by using a typed
NULL first argument, but this is a bit ugly. Add a helper to do this,
and replace the handful of instances of the code pattern with it.
Instances were found with this Coccinelle script:
@struct_size_t@
identifier STRUCT, MEMBER;
expression COUNT;
@@
- struct_size((struct STRUCT *)\(0\|NULL\),
+ struct_size_t(struct STRUCT,
MEMBER, COUNT)

Upstream Status: Posted https://lore.kernel.org/netdev/20240307222510.53654-1-mschmidt@redhat.com/
This series removes the use of the heavy-weight PTP hardware semaphore in the gettimex64 path. Instead, serialization of access to the time
register is done using a host-side spinlock. The timer hardware is shared between PFs on the PCI adapter, so the spinlock must be shared between ice_pf instances too.
In practice, it gets rid of the frequent "PTP failed to get time" error messages that certain customers are seeing.
Although the series is not yet merged upstream, it has received favorable reviews from Intel developers. There are still some suggestions for minor improvements, but implementing them will not change the solution materially. The series targets net-next, which is closed at the moment, so I am blocked from posting an update to netdev right now. At the same time, the issue has a high impact for customers. We need to deliver the fix soon. Once the final version gets accepted by upstream, I will follow up by backporting the remaining differences and referencing the final commit IDs.
Tested:
- I tested it myself using the additional test code that's referenced from patch 2/3 in the series.
- A scratch build of the patchset backported to 9.2.z was tested by the reporting customer and by QE. In both cases it was confirmed that the PTP error messages went away. Obviously, because the code that prints the error message is removed by the patches. It's still good to know that the customer did not report any bad side effects.
- It was tested by the Intel validation team and they did not find any issues with it. (Information relayed to me by Tony Nguyen.)
- The CKI artifact (both plain & RT) has been tested by QE.

At the time of LPAR dump, before kexec hands over control to kdump
kernel, DDWs (Dynamic DMA Windows) are scanned and added to the FDT.
For the SR-IOV case, default DMA window "ibm,dma-window" is removed from
the FDT and DDW added, for the device.
Now, kexec hands over control to the kdump kernel.
When the kdump kernel initializes, PCI busses are scanned and IOMMU
group/tables created, in pci_dma_bus_setup_pSeriesLP(). For the SR-IOV
case, there is no "ibm,dma-window". The original commit: b1fc44eaa9ba,
fixes the path where memory is pre-mapped (direct mapped) to the DDW.
When TCEs are direct mapped, there is no need to initialize IOMMU
tables.
iommu_table_setparms_lpar() only considers "ibm,dma-window" property
when initiallizing IOMMU table. In the scenario where TCEs are
dynamically allocated for SR-IOV, newly created IOMMU table is not
initialized. Later, when the device driver tries to enter TCEs for the
SR-IOV device, NULL pointer execption is thrown from iommu_area_alloc().
The fix is to initialize the IOMMU table with DDW property stored in the
FDT. There are 2 points to remember:
1. For the dedicated adapter, kdump kernel would encounter both
default and DDW in FDT. In this case, DDW property is used to
initialize the IOMMU table.
2. A DDW could be direct or dynamic mapped. kdump kernel would
initialize IOMMU table and mark the existing DDW as
"dynamic". This works fine since, at the time of table
initialization, iommu_table_clear() makes some space in the
DDW, for some predefined number of TCEs which are needed for
kdump to succeed.
Fixes: b1fc44eaa9ba ("pseries/iommu/ddw: Fix kdump to work in absence of ibm,dma-window")

The `.BTF_ids` section of vmlinux is pre-filled with zeroed BTF ID entries during the build and afterwards patched by resolve_btfids with correct values. Since resolve_btfids always writes in host-native endianness, it relies on libelf to do the translation when the target ELF is cross-compiled to a different endianness.
Unfortunately, the translation will corrupt the flags fields of SET8 entries because these were written during vmlinux compilation and are in the correct endianness already. This will lead to numerous BPF selftests failures.
The issue mainly affects CKI-compiled s390x (big-endian) kernels as these are cross-compiled on little-endian machines.
This MR backports upstream patches which resolve the problem.
