Subject: [PATCH] cpuidle menu: remove 8 bytes of padding on 64 bit builds
Date: Mon, 25 Jan 2010 10:59:16 +0000 [thread overview]
Message-ID: <1264417156.2039.9.camel@localhost> (raw)
reorder struct menu_device to remove 8 bytes of padding on 64 bit
builds. Size drops from 136 to 128 bytes, so possibly needing one fewer
cache lines.
Signed-off-by: Richard Kennedy <richard@rsk.demon.co.uk>
-----
patch against 2.6.33-rc5
compile tested only
regards
Richard
