Have you measured the performance impact of this ? The second part of

Rearrange 64K PTE bits to free up bits 3, 4, 5 and 6
in the 64K backed HPTE pages. This along with the earlier
patch will entirely free up the four bits from 64K PTE.
The bit numbers are big-endian as defined in the ISA3.0
This patch does the following change to 64K PTE backed
by 64K H
