Subject: MIPS: PNX8550: Sort out machine halt, restart and powerdown functions.
X-Git-Tag: v2.6.36-rc7~1^2~9
X-Git-Url: https://bbs.cooldavid.org/git/?p=net-next-2.6.git;a=commitdiff_plain;h=c1b47e9508f74c152407323260f9fbb980d2fde1

MIPS: PNX8550: Sort out machine halt, restart and powerdown functions.

No rubbish printks - those belong to userspace.  The halt function now
actually halts the system and the poweroff function was deleted because
it didn't actually power down the system.
