[PATCH] gfp_t: infrastructure
Beginning of gfp_t annotations: - -Wbitwise added to CHECKFLAGS - old __bitwise renamed to __bitwise__ - __bitwise defined to either __bitwise__ or nothing, depending on __CHECK_ENDIAN__ being defined - gfp_t switched from __nocast to __bitwise__ - force cast to gfp_t added to __GFP_... constants - new helper - gfp_zone(); extracts zone bits out of gfp_t value and casts the result to int Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
