https://lore.kernel.org/all/20250113170619.484698-2-yury.khrustalev@xxxxxxx/ patchset
has been queued to arm64/for-next/pkey_unrestricted which is causing a build break
in the selftest/powerpc builds.
Commit 6d61527d931ba ("mm/pkey: Add PKEY_UNRESTRICTED macro") added a macro
PKEY_UNRESTRICTED to handle implicit literal value of 0x0 (which is "unrestricted").
Add the same to selftest/powerpc/pkeys.h to fix the reported build break.
