[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
