[PATCH] bitops: generic {,test_and_}{set,clear,change}_bit()

This patch introduces the C-language equivalents of the functions below:

void set_bit(int nr, volatile unsigned long *addr);
void clear_bit(int nr, volatile unsigned long *addr);
void change_bit(int nr, volatile unsigned long *addr);
int test_and_set_bit(int nr, volatile unsigned long *addr);
int test_and_clear_bit(int nr, volatile unsigned long *addr);
int test_and_change_bit(int nr, volatile unsigned long *addr);

In include/asm-generic/bitops/atomic.h
