[PATCH] Use helpers to obtain task pid in printks (arch code)
From: Alexey Dobriyan <adobriyan@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.
