[parisc-linux] hwclock

[Alex deVries]

There's been some discussion on IRC about not always having to set the
clock when in userspace.  I had a quick look at it, and it shouldn't be
too hard.  We just need a parisc version of hwclock which calls the
PDC_TOD functions.

It should be reasonably easy to get this going, so if someone's looking
for an unintrusive and simple task, have a look at it.

hwclock is part of the ever-terrible utils-linux package, and you should
be able to use hwclock-ppc.c as a starting point.

CONFIG_GENRTC in fact does use PDC_TOD.
Randolph Chung had hwclock working for PXC-L/L2 machines and I tested it
on my c3k (32-bit) a few weeks back.
If it's broken, then it's a "recent" change.

Works for me on B180L (once I created /dev/rtc).  Kernel source as of
CVS 12 hours ago.
