Subject: [PATCH 06/46] x86: align per-cpu section to configured cache bytes
Date: Tue, 21 Mar 2006 17:20:54 +0100 [thread overview]
Message-ID: <114295805457-git-send-email-sam@ravnborg.org> (raw)
In-Reply-To: <1142958054501-git-send-email-sam@ravnborg.org>
This matches the fix for a bug seen on x86-64. Test booted on old hardware
that had 32 byte cachelines to begin with.
