This goes on top of Walter's patch titled "kasan: fix KASAN unit tests
for tag-based KASAN" (already in mm tree).

Bugzilla link: https://bugzilla.kernel.org/show_bug.cgi?id=203497

Thanks to Walter Wu for debugging and testing.

Andrey Konovalov (4):
  kasan: don't tag stacks allocated with pagealloc
  kasan, arm64: don't instrument functions that enable kasan
  kasan: allow enabling stack tagging for tag-based mode
  kasan: adjust kasan_stack_oob for tag-based mode
