ThinkPad 850 Patches for 2.2.16

[Olaf Hering]

Hi,

Linar Yusupov did some patches for the Thinkpad 850 to make sound work
on these machines. It fixes also some typos for /proc/cpuinfo.

I'm not sure if the CAROLINA_IRQ_EDGE_MASK_HI change breaks anything else.

The sound stuff should be moved out of arch/ppc into the driver cs4232, you
can't have it as a module right now. xmms works fine, but I have many
dropouts. Any ideas how to finetune that?
That sound-patch will proably break the other PReP machines, I will test
it on the 43p 133 later. We need proably a _PREP_IBM_portable or so.





Gruss Olaf
