Subject: [PATCH 2/2] [x86] align per-cpu section to configured cache bytes
Date: Fri, 27 Jan 2006 14:02:47 -0800 (PST)	[thread overview]
Message-ID: <20060127220247.13917.8544.sendpatchset@tetsuo.zabbo.net> (raw)
In-Reply-To: <20060127220242.13917.839.sendpatchset@tetsuo.zabbo.net>

[x86] align per-cpu section to configured cache bytes

This matches the fix for a bug seen on x86-64.  Test booted on old hardware
that had 32 byte cachelines to begin with.
