bitops: introduce CONFIG_GENERIC_FIND_BIT_LE
This introduces CONFIG_GENERIC_FIND_BIT_LE to tell whether to use generic implementation of find_*_bit_le() in lib/find_next_bit.c or not. For now we select CONFIG_GENERIC_FIND_BIT_LE for all architectures which enable CONFIG_GENERIC_FIND_NEXT_BIT. But m68knommu wants to define own faster find_next_zero_bit_le() and continues using generic find_next_{,zero_}bit(). (CONFIG_GENERIC_FIND_NEXT_BIT and !CONFIG_GENERIC_FIND_BIT_LE) Signed-off-by: Akinobu Mita <akinobu.mita@gmail.com> Cc: Greg Ungerer <gerg@uclinux.org> Cc: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
