[PATCH] bit reverse library This patch provides two bit reverse functions and bit reverse table. - reverse the order of bits in a u32 value u8 bitrev8(u8 x); - reverse the order of bits in a u32 value u32 bitrev32(u32 x); - byte reverse table const u8 byte_rev_table[256]; Signed-off-by: Akinobu Mita <akinobu.mita@gmail.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org> 2006-12-08 02:36:25 -08:00			`#ifndef _LINUX_BITREV_H`
