Kumar Gala f50b153b19 [PATCH] ppc32: Support 36-bit physical addressing on e500
To add support for 36-bit physical addressing on e500 the following changes
have been made.  The changes are generalized to support any physical address
size larger than 32-bits:

* Allow FSL Book-E parts to use a 64-bit PTE, it is 44-bits of pfn, 20-bits
  of flags.

* Introduced new CPU feature (CPU_FTR_BIG_PHYS) to allow runtime handling of
  updating hardware register (SPRN_MAS7) which holds the upper 32-bits of
  physical address that will be written into the TLB.  This is useful since
  not all e500 cores support 36-bit physical addressing.

* Currently have a pass through implementation of fixup_bigphys_addr

* Moved _PAGE_DIRTY in the 64-bit PTE case to free room for three additional
  storage attributes that may exist in future FSL Book-E cores and updated
  fault handler to copy these bits into the hardware TLBs.
