Merge tag 'asm-generic-6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic

Pull asm-generic updates from Arnd Bergmann:
 "Most of this is part of my ongoing work to clean up the system call
  tables. In this bit, all of the newer architectures are converted to
  use the machine readable syscall.tbl format instead in place of
  complex macros in include/uapi/asm-generic/unistd.h.

  This follows an earlier series that fixed various API mismatches and
  in turn is used as the base for planned simplifications.

  The other two patches are dead code removal and a warning fix"
