compat: move cp_compat_stat to common code
struct stat / compat_stat is the same on all architectures, so cp_compat_stat should be, too. Turns out it is, except that various architectures have slightly and some high2lowuid/high2lowgid or the direct assignment instead of the SET_UID/SET_GID that expands to the correct one anyway. This patch replaces the arch-specific cp_compat_stat implementations with a common one based on the x86-64 one. Signed-off-by: Christoph Hellwig <hch@lst.de> Acked-by: David S.
