Subject: [PATCH 1/1] define stub32_checkpoint etc
Date: Wed, 20 Jan 2010 13:43:53 -0600 [thread overview]
Message-ID: <20100120194353.GA16902@us.ibm.com> (raw)
Don't get too excited this doesn't make checkpoint work on x86-64,
but at least hooks the syscall :) My hope is to actually get it
working by tomorrow.
