[PATCH] ppc32: support for e500 and 85xx 

Here is both a GNU style and BK patch for adding support for the e500 core and
85xx platform to 2.6.  This is pretty much a direct port from 2.4 with a bit
of cleanup around the edges.

---help---
This option enables kernel support for the Signal Processing
Extensions (SPE) to the PowerPC processor. The kernel currently
supports saving and restoring SPE registers, and turning on the
'spe enable' bit so user processes can execute SPE instructions.
This option is only usefully if you have a processor that supports
SPE (e500, otherwise known as 85xx series), but does not have any
affect on a non-spe cpu (it does, however add code to the kernel).
If in doubt, say Y here.
