Well that's quite surprising....

I'm no chip head...but I was expecting the POWER/IBMi to be immune given
the protections in place for it's shared address space vs x86/windows
single process VM.

I wonder if it's PASE specific issue...that I could see...

And given the usage of PASE in the OS now (networking, Java, ect) you can't
have IBMi w/o PASE like you used to be able to have OS/400 without PASE.

Last time I read about the subject, POWER processors were in-order
processors. This flaw sounds like its around the speculative processing
used by x86, so I doubt the flaw affects POWER. Its also why there is
talk
of x86 processor performance being affected by a patch. If they disable
this speculative processing, it neuters a significant paradigm used by
these processors.
