Applied to powerpc next, thanks.

I reworded one comment a little, from:
/* 2^11 PTEGS / 2^18 bytes is the minimum htab size permitted * by the architecture */
to: /* * 2^11 PTEGS of 128 bytes each, ie. 2^18 bytes is the minimum htab * size permitted by the architecture. */
To avoid any confusion about the "/" referring to division.
cheers
