[PATCH] Use helpers to obtain task pid in printks (arch code)
Pavel Emelyanov
xemul at openvz.org
Mon Aug 27 00:30:06 PDT 2007
From: Alexey Dobriyan <adobriyan at openvz.org>
One of the easiest things to isolate is the pid printed in kernel
log. There was a patch, that made this for arch-independent code,
this one makes so for arch/xxx files.
It took some time to cross-compile it, but hopefully these are all
the printks in arch code.
