Subject: [patch 41/47] update include/asm-generic/bitops.h
Date: Tue, 14 Feb 2006 14:04:32 +0900	[thread overview]

Currently include/asm-generic/bitops.h is not referenced from anywhere.
But it will be the benefit of those who are trying to port Linux to
another architecture.

So update it by same manner

- * Also note, these routines assume that you have 32 bit longs.
