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 :-)

=20
Second and third patch is to allow guest controlling "G"-Guarded and =

"E"-Endian TLB attributes respectively.

=20
Fourth patch is moving functions/logic in common code so they can be =

used on booke also.

Fifth and Sixth patch is actually setting caching attributes =

(TLB.WIMGE) using corresponding Linux pte.

Thanks, applied 1/6 - 3/6 to kvm-ppc-queue.

v3->v5
- Fix tlb-reference-flag clearing issue (patch 4/6)
- There was a patch (4/6 powerpc: move linux pte/hugepte search to =

more generic file)

  in the last series of this patchset which was moving pte/hugepte =

search functions to

  generic file. That patch is no more needed as some other patch is =

already applied to fix that :)

=20
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.
=20
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
 kvm: powerpc: keep only pte search logic in lookup_linux_pte
 kvm: booke: clear host tlb reference flag on guest tlb invalidation
 kvm: powerpc: use caching attributes as per linux pte
