m68k/bitops: Correct signature of test_bit()
mm/filemap.c: In function ‘clear_bit_unlock_is_negative_byte’: mm/filemap.c:933: warning: passing argument 2 of ‘test_bit’ discards qualifiers from pointer target type Make the bitmask pointed to by the "vaddr" parameter volatile to fix this, like is done on other architectures.
