From: Geert Uytterhoeven <geert@xxxxxxxxxxxxxx>
Subject: m68k/bitops: always include <asm-generic/bitops/find.h>
Currently <asm/bitops.h> only includes <asm-generic/bitops/find.h> if
CONFIG_CPU_HAS_NO_BITFIELDS=y. This used to be fine, as the code for
CONFIG_CPU_HAS_NO_BITFIELDS=n implemented everything provided by
<asm-generic/bitops/find.h>.
However, e49c614e6b37254b ("lib: optimize cpumask_next_and()") added
find_next_and_bit(), which is now not available if
CONFIG_CPU_HAS_NO_BITFIELDS=y:
lib/find_bit_benchmark.c: In function `test_find_next_and_bit':
lib/find_bit_benchmark.c:115: error: implicit declaration of function `find_next_and_bit'
Move the inclusion of <asm-generic/bitops/find.h> outside the #ifdef to
fix this.
