Should I use this patch agains which tree?

Right now, I have Linus's tree, yours (cited above) and I am, up to now,
I had been compiling everything from Linus's v3.2 tag: both a vanilla
kernel, as asked by Bjorn and with the patch that I mentioned to Linus ("the
one that makes things boot").

If it applies (and newer kernels don't have things which your patch needs),
I will keep working with Linus's v3.2 tag.

When I compiled from your branch for-pci2 from linux-yinghai.git (without
any extra patches), it *did* boot, but noticed one thing weird: using htop
and in single user mode, it reported 100% of CPU in use. With regular top, a
more fine grained output revealed that no processes were using the CPU, but
that almost all of the time was spent in kernel mode.

Anyway, as you asked, I put the log of what I see at

http://www.ime.usp.br/~rbrito/linux/clevo/2012-01-13-0951-yanghai-for-pci2-branch/

Thanks for your (everybody else's) kindness/helpfulness with these multiple
issues.
