KOSAKI Motohiro 3b4798cbc1 oom-kill: show virtual size and rss information of the killed process 
In a typical oom analysis scenario, we frequently want to know whether the
killed process has a memory leak or not at the first step.  This patch
adds vsz and rss information to the oom log to help this analysis.  To
save time for the debugging.

example:
===================================================================
rsyslogd invoked oom-killer: gfp_mask=0x201da, order=0, oom_adj=0
Pid: 1308, comm: rsyslogd Not tainted 2.6.32-rc6 #24
Call Trace:
[<ffffffff8132e35b>] ?_spin_unlock+0x2b/0x40
[<ffffffff810f186e>] oom_kill_process+0xbe/0x2b0
