[BK PATCH] i386 timer changes for 2.5.41

[Greg KH <greg@kroah.com>]

Hi Linus,

I've taken the i386 timer.c patches that John Stultz has been working on
for a while, made some minor tweaks, added them to a bk tree, and tested
them on all the boxes that I have access too.  Here's the resulting
changesets:

Please pull from bk://lsm.bkbits.net/timer-2.5

These split up the time.c code to handle different interrupt time
sources, moving the code into a new arck/i386/kernel/timers directory.
This is going to get more important as new timer sources become
available (like IBM's Summit chipset), and removes a lot of #ifdefs from
the existing code.

The differences from John's last patches are:
	- use bk to show the history of the time.c file moves
	- added proper documentation for struct timer_opts
	- init() in timer_opts now returns 0 for success
	- timer array is now static, and NULL terminated to make
	  adding new sources an easier patch.

thanks,

greg k-h
