From: Bharat Bhushan <bharat.bhushan at 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"-Endiany TLB attributes respectively.

Rest of patches is about setting caching attributes (TLB.WIMGE) using
corresponding Linux pte.

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: booke: Add linux pte lookup like booke3s
  kvm: powerpc: use caching attributes as per linux pte
