pkey-helpers.h defines PKEY_UNRESTRICTED itself when the macro is not
already known, a stopgap from when the generic definition was still
under review. It has been merged since, commit 6d61527d931b ("mm/pkey:
Add PKEY_UNRESTRICTED macro"), and pkey-helpers.h already includes
<linux/mman.h>, so the guard is never taken. Honour the FIXME and drop
it.
The mm selftests build against the headers of the kernel source, see
Documentation/dev-tools/kselftest.rst. Building them without "make
headers", against system headers predating the macro, now fails to
compile instead of quietly falling back.
No functional change intended.
