Subject: selftests/mm: fix build warnings on ppc64
Date: Tue, 21 May 2024 13:02:19 +1000

Fix warnings like:

  In file included from uffd-unit-tests.c:8:
  uffd-unit-tests.c: In function `uffd_poison_handle_fault':
  uffd-common.h:45:33: warning: format `%llu' expects argument of type
  `long long unsigned int', but argument 3 has type `__u64' {aka `long
  unsigned int'} [-Wformat=]

By switching to unsigned long long for u64 for ppc64 builds.
