Merge tag 'asm-generic-fixes-6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic

Pull asm-generic fixes from Arnd Bergmann:
 "These are some bugfixes for system call ABI issues I found while
  working on a cleanup series. None of these are urgent since these bugs
  have gone unnoticed for many years, but I think we probably want to
  backport them all to stable kernels, so it makes sense to have the
  fixes included as early as possible.

  One more fix addresses a compile-time warning in kallsyms that was
  uncovered by a patch I did to enable additional warnings in 6.10. I
  had mistakenly thought that this fix was already merged through the
  module tree, but as Geert pointed out it was still missing"
