Linus Torvalds 26cf46be95 vfs: micro-optimize acl_permission_check() 
It's a hot function, and we're better off not mixing types in the mask
calculations.  The compiler just ends up mixing 16-bit and 32-bit
operations, for no good reason.

So do everything in 'unsigned int' rather than mixing 'unsigned int'
masking with a 'umode_t' (16-bit) mode variable.

This, together with the parent commit (47a150edc2: "Cache user_ns in
struct cred") makes acl_permission_check() much nicer.

Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
