Paulus: please consider for your 2.6.27 tree.
Updated with comments from Kumar, Milton, Dave Woodhouse and Mark
'NKOTB' Nelson.
- Changed thread_struct array definition to be cleaner
- Updated CPU_FTRS_POSSIBLE
- Updated Kconfig typo and dupilicate
- Added comment to clarify ibm,vmx = 2 really means VSX.
One question I was wondering about is the "user space" view of VSX.
Is the intent to have it seem like there is a unique register set for
VSX separate from FP or AltiVec?
(This gets into what the ABI changes look like).
