[PATCH 12/23] Update sysrq-B to use emergency_restart()

From: Eric W. Biederman
Date: Tue Jul 26 2005 - 14:15:42 EST



sysrq calls into the reboot path from an interrupt handler
we can either push the code do into process context and
call kernel_restart and get a clean reboot or we can simply
reboot the machine, and increase our chances of actually
rebooting. emergency_reboot() seems like the closest match
to what we have previously done, and what we want.
