[PATCH] bitops: generic minix_{test,set,test_and_clear,test,find_first_zero}_bit()
This patch introduces the C-language equivalents of the functions below: int minix_test_and_set_bit(int nr, volatile unsigned long *addr); int minix_set_bit(int nr, volatile unsigned long *addr); int minix_test_and_clear_bit(int nr, volatile unsigned long *addr); int minix_test_bit(int nr, const volatile unsigned long *addr); unsigned long minix_find_first_zero_bit(const unsigned long *addr, unsigned long size); In include/asm-generic/bitops/minix.h and include/asm-generic/bitops/minix-le.h This code largely copied from: include/asm-sparc/bitops.h Signed-off-by: Akinobu Mita <mita@miraclelinux.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
