Subject: [PATCH] fix comment in Light-weight-syscall code
Date: Thu, 10 Jul 2008 22:04:15 +0200 [thread overview]
Message-ID: <200807102204.15886.deller@gmx.de> (raw)
The comment for the lws-atomic system call userspace helper
function mentions r22 and r23 as input registers, but I couldn't
find any usage of those registers in the code.
This patch fixes this and corrects another small typo as well.
