Pull apparmor updates from John Johansen:
 "Features:
   - extend next/check table to add support for 2^24 states to the state
     machine.
   - rework capability audit cache to use broader cred information
     instead of just the profile. Also add a time stamp so old entries
     can be aged out of the cache.

  Bug Fixes:
   - fix 'Do simple duplicate message elimination' to clear previous
     state when updating in capability audit cache
   - Fix memory leak for aa_unpack_strdup()
   - properly handle cx/px lookup failure when in complain mode
   - allocate xmatch for nullpdb inside aa_alloc_null fixing a NULL ptr
     deref of tracking profiles in when in complain mode

  Cleanups:
   - Remove everything being reported as deadcode
   - replace misleading 'scrubbing environment' phrase in debug print
   - Remove unnecessary NULL check before kvfree()
   - clean up duplicated parts of handle_onexec()
   - Use IS_ERR_OR_NULL() helper function
   - move new_profile declaration to top of block instead immediately
     after label to remove C23 extension warning

  Documentation:
   - add comment to document capability.c:profile_capable ad ptr
     parameter can not be NULL
   - add comment to document first entry is in packed perms struct is
     reserved for future planned expansion.
   - Update LSM/apparmor.rst add blurb for DEFAULT_SECURITY_APPARMOR"
