[ Upstream commit e8b8c5264d4ebd248f60a5cef077fe615806e7a0 ]

Fix build error on ppc64:
dev_in_maps.c: In function ‘get_file_dev_and_inode’:
dev_in_maps.c:60:59: error: format ‘%llu’ expects argument of type
‘long long unsigned int *’, but argument 7 has type ‘__u64 *’ {aka ‘long
unsigned int *’} [-Werror=format=]

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