Attempt to reduce stack usage in sys.c (linux-2.6.12-rc1-mm3). Stack usage was noted using checkstack.pl. Specifically
Before patch ------------ sys_reboot - 256
After patch ----------- sys_reboot - none (register usage only)
Along the way, wrap code to 80 column width and cleanup lock usage.
Your "cleanup lock usage" increases the number of lock_kernel() calls quite a bit, which is not really a cleanup but simply bloat.
Seperate out your patches; don't sneak these supposed-cleanups into stack uage patches.
