Re: linux-next: Tree for Jul 30 [build failure on arm64]

[Christoph Hellwig]

Ok, looks like my baseline had arm64 defconfig fail due to a missing
include already, so the script didn't see a regression due to the
existing failure in ptrauth_keys_init_user.

Looks like moving the definÑtion to asm-generic/compat.h is a better
idea better anyway.
