The fault-inject.h users across the kernel need to add a lot of #ifdef
CONFIG_FAULT_INJECTION to cater for shortcomings in the header. Make
fault-inject.h self-contained for CONFIG_FAULT_INJECTION=n, and add stubs
for DECLARE_FAULT_ATTR(), setup_fault_attr(), should_fail_ex(), and
should_fail() to allow removal of conditional compilation.

futex_init() never calls alloc_large_system_hash() with numentries set to

futex: Prevent the reuse of stale pi_state
Jiri Slaby reported a futex state inconsistency resulting in -EINVAL during
a lock operation for a PI futex. It requires that the a lock process is
interrupted by a timeout or signal:
T1 Owns the futex in user space.
T2 Tries to acquire the futex in kernel (futex_lock_pi()). Allocates a
pi_state and attaches itself to it.
T2 Times out and removes its rt_waiter from the rt_mutex. Drops the
rtmutex lock and tries to acquire the hash bucket lock to remove
the futex_q. The lock is contended and T2 schedules out.
T1 Unlocks the futex (futex_unlock_pi()). Finds a futex_q but no
rt_waiter. Unlocks the futex (do_uncontended) and makes it available
to user space.
T3 Acquires the futex in user space.
T4 Tries to acquire the futex in kernel (futex_lock_pi()). Finds the
existing futex_q of T2 and tries to attach itself to the existing
pi_state. This (attach_to_pi_state()) fails with -EINVAL because uval
contains the TID of T3 but pi_state points to T1.
It's incorrect to unlock the futex and make it available for user space to
acquire as long as there is still an existing state attached to it in the
kernel.
T1 cannot hand over the futex to T2 because T2 already gave up and started
to clean up and is blocked on the hash bucket lock, so T2's futex_q with
the pi_state pointing to T1 is still queued.
T2 observes the futex_q, but ignores it as there is no waiter on the
corresponding rt_mutex and takes the uncontended path which allows the
subsequent caller of futex_lock_pi() (T4) to observe that stale state.
To prevent this the unlock path must dequeue all futex_q entries which
point to the same pi_state when there is no waiter on the rt mutex. This
requires obviously to make the dequeue conditional in the locking path to
prevent a double dequeue. With that it's guaranteed that user space cannot
observe an uncontended futex which has kernel state attached.

futex: Fix hardcoded flags
Xi reported that commit 5694289ce183 ("futex: Flag conversion") broke
glibc's robust futex tests.
This was narrowed down to the change of FLAGS_SHARED from 0x01 to
0x10, at which point Florian noted that handle_futex_death() has a
hardcoded flags argument of 1.
Change this to: FLAGS_SIZE_32 | FLAGS_SHARED, matching how
futex_to_flags() unconditionally sets FLAGS_SIZE_32 for all legacy
futex ops.

futex: Don't include process MM in futex key on no-MMU
On no-MMU, all futexes are treated as private because there is no need
to map a virtual address to physical to match the futex across
processes. This doesn't quite work though, because private futexes
include the current process's mm_struct as part of their key. This makes
it impossible for one process to wake up a shared futex being waited on
in another process.
Fix this bug by excluding the mm_struct from the key. With
a single address space, the futex address is already a unique key.

futex: Resend potentially swallowed owner death notification
Commit ca16d5bee5 ("futex: Prevent robust futex exit race") addressed
two cases when tasks waiting on a robust non-PI futex remained blocked
despite the futex not being owned anymore:
* if the owner died after writing zero to the futex word, but before
waking up a waiter
* if a task waiting on the futex was woken up, but died before updating
the futex word (effectively swallowing the notification without acting
on it)
In the second case, the task could be woken up either by the previous
owner (after the futex word was reset to zero) or by the kernel (after
the OWNER_DIED bit was set and the TID part of the futex word was reset
to zero) if the previous owner died without the resetting the futex.
Because the referenced commit wakes up a potential waiter only if the
whole futex word is zero, the latter subcase remains unaddressed.
Fix this by looking only at the TID part of the futex when deciding
whether a wake up is needed.

mm/truncate: Inline invalidate_complete_page() into its one caller
invalidate_inode_page() is the only caller of invalidate_complete_page()
and inlining it reveals that the first check is unnecessary (because we
hold the page locked, and we just retrieved the mapping from the page).
Actually, it does make a difference, in that tail pages no longer fail
at this check, so it's now possible to remove a tail page from a mapping.
