------------------------------------------------------
Subject: i386: stop bogus nmi & softlockup warnings in show_mem
From: Prarit Bhargava <[EMAIL PROTECTED]>
When dumping memory via sysrq-m it is possible to take a bogus NMI watchdog
or softlockup watchdog because the dump can take a long time on big memory
systems.
Occasionally tickle the watchdog when doing the dump.
