This doesn't apply on top of my "alpha: enable GENERIC_ENTRY" series

https://lore.kernel.org/linux-alpha/20260902184058.198679-1-linmag7@gmail.com/T/#t

That series moves alpha's syscall entry onto the generic entry
framework and removes syscall_trace_enter() and its direct
audit_syscall_entry() call entirely - verified with git am against
GENERIC_ENTRY applied, it fails at exactly this hunk.
You don't need a replacement alpha patch, though. Once GENERIC_ENTRY
lands, alpha's syscall entry goes through
syscall_enter_from_user_mode_randomize_stack(), which already calls
syscall_enter_audit() as part of the shared entry helpers
(include/linux/entry-common.h). I applied patch 1/13 alone on top of
GENERIC_ENTRY and confirmed alpha's entry path already routes through
the updated __audit_syscall_entry() - no alpha-specific code needed.
So for alpha, you can drop this patch in the next revision rather
than rebase it.
