[PATCH 0/6 v3] kvm: powerpc: use cache attributes from linux pte

[Bharat Bhushan <r65777@freescale.com>]

From: Bharat Bhushan <bharat.bhushan@freescale.com>

First patch is a typo fix where book3e define _PAGE_LENDIAN while it should be
defined as _PAGE_ENDIAN. This seems to show that this is never exercised :-)

Second and third patch is to allow guest controlling "G"-Guarded and
"E"-Endian TLB attributes respectively.

Fourth and fifth patch is moving functions/logic in common code
so they can be used on booke also.

Sixth patch is actually setting caching attributes (TLB.WIMGE) using
corresponding Linux pte.

v2->v3
 - now lookup_linux_pte() only have pte search logic and it does not
   set any access flags in pte. There is already a function for setting
   access flag which will be called explicitly where needed.
   On booke we only need to search for pte to get WIMG.

v1->v2
 - Earlier caching attributes (WIMGE) were set based of page is RAM or not
   But now we get these attributes from corresponding Linux PTE.

Bharat Bhushan (6):
  powerpc: book3e: _PAGE_LENDIAN must be _PAGE_ENDIAN
  kvm: powerpc: allow guest control "E" attribute in mas2
  kvm: powerpc: allow guest control "G" attribute in mas2
  powerpc: move linux pte/hugepte search to more generic file
  kvm: powerpc: keep only pte search logic in lookup_linux_pte
  kvm: powerpc: use caching attributes as per linux pte
