[PATCH] bitops: x86_64: use generic bitops
- remove sched_find_first_bit() - remove generic_hweight{64,32,16,8}() - remove ext2_{set,clear,test,find_first_zero,find_next_zero}_bit() - remove minix_{test,set,test_and_clear,test,find_first_zero}_bit() Signed-off-by: Akinobu Mita <mita@miraclelinux.com> Cc: Andi Kleen <ak@muc.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
