Hi guys,
Just a query here, there was a patch for /chosen/initrd,start and initrd,end
variables gained from firmware or so, which allowed booting without getting
those values into r3/r4, does anyone know the maintainer/author of that
patch?
Also, what are the chances of pushing it for 2.6.23 or

Rework timebase handoff to play nice with configurations with more than
2 cores, as well as with CPU hotplug.
Previous scheme just pushed out the current timebase from the giving
core to all cores without caring if they wanted it or not, nor checking
if they'd taken it. The taking side didn't

It makes head_64.S a bit more readable and will allow us to move the

Hi,
I'm ignorant when it comes to IO access, so I hope this isn't rubbish (if
it is, I would appreciate being corrected).
It took me more than a glance to see what the difference is supposed to be
between wmb() and mmiowb(). I think especially because mmiowb isn't really
like a write barrier.
