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.
