Merge branch 'siginfo-si_trapno-for-v5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull siginfo si_trapno updates from Eric Biederman:
"The full set of si_trapno changes was not appropriate as a fix for the
newly added SIGTRAP TRAP_PERF, and so I postponed the rest of the
related cleanups.
This is the rest of the cleanups for si_trapno that reduces it from
being a really weird arch special case that is expect to be always
present (but isn't) on the architectures that support it to being yet
another field in the _sigfault union of struct siginfo.
The changes have been reviewed and marinated in linux-next. With the
removal of this awkward special case new code (like SIGTRAP TRAP_PERF)
that works across architectures should be easier to write and
maintain"
* 'siginfo-si_trapno-for-v5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace:
signal: Rename SIL_PERF_EVENT SIL_FAULT_PERF_EVENT for consistency
signal: Verify the alignment and size of siginfo_t
signal: Remove the generic __ARCH_SI_TRAPNO support
signal/alpha: si_trapno is only used with SIGFPE and SIGTRAP TRAP_UNK
signal/sparc: si_trapno is only used with SIGILL ILL_ILLTRP
arm64: Add compile-time asserts for siginfo_t offsets
arm: Add compile-time asserts for siginfo_t offsets
sparc64: Add compile-time asserts for siginfo_t offsets
