| |
This patch introduces the C-language equivalents of the functions below:
HAVE_ARCH_MINIX_BITOPS is defined when the architecture has its own version of these functions.
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);
This code largely copied from: include/asm-sparc/bitops.h
