Subject: [PATCH] kernel: add byteorder function with alignment fixups
Date: Thu, 20 Mar 2008 12:41:27 -0700 [thread overview]
Message-ID: <1206042087.17059.15.camel@brick> (raw)
In-Reply-To: <20080320190953.GR10722@ZenIV.linux.org.uk>
Add helpers for the pattern put_unaligned(cpu_to_le32(val), (__le32 *)p)
to linux/unaligned.h
Repeat for various combinations of le/be and 64/32/16 bit.
Signed-off-by: Harvey Harrison <harvey.harrison@gmail.com>

Applies on top of my last patch, makes it a symmetric API.
