The style that we normally use in asm-generic is to test the macro itself
for existence, so in asm-generic, do:
#ifndef find_next_zero_bit_le
extern unsigned long find_next_zero_bit_le(const void *addr,
unsigned long size, unsigned long offset);
#endif
and in the architectures, write
static inline unsigned long find_next_zero_bit_le(const void *addr,
unsigned long size, unsigned long offset)
#define find_next_zero_bit_le find_next_zero_bit_le
But CONFIG_GENERIC_FIND_{NEXT_BIT,BIT_LE,LAST_BIT} options are used to
test for existence of find bitops now.
This patch series switches find bitops to follow the normal style
described above. This change enables arm and s390 to use
asm-generic/bitops/le.h header file and fixes m68knommu build error
due to the lack of find_next_bit_le().
Akinobu Mita (6):
arch: add #define for each of optimized find bitops
bitops: add #ifndef for each of find bitops
arch: remove CONFIG_GENERIC_FIND_{NEXT_BIT,BIT_LE,LAST_BIT}
arm: use asm-generic/bitops/le.h
s390: use asm-generic/bitops/le.h
m68knommu: fix build error dule to the lack of find_next_bit_le()
