Can you break this patch into a few parts that are easier to review than
one giant patch. Start by adding the PPR ftr bits, then the extra space
in the paca, then the new macros, then use the new infrastructure. I'm
sure you can get 5 or so patches which will be much easier to

As we keep increasing PGTABLE_RANGE we need not increase the virual
map area for kernel.

Increase the number of valid VSID bits in slbmte instruction.
We will use the new bits when we increase valid VSID bits.

This patch makes the high psizes mask as an unsigned char array
so that we can have more than 16TB. Currently we support upto
64TB

This patch convert different functions to take virtual page number
instead of virtual address. Virtual page number is virtual address
shifted right by VPN_SHIFT (12) bits.

can't directly include pgtable.h in these header because there is

Hi Linus !
Here's the powerpc batch for 3.6 merge window. Notable highlights:
- iommu improvements from Anton removing the per-iommu global lock
in favor of dividing the DMA space into pools, each with its own lock,
and hashed on the CPU number. Along with making the locking more fine
