From: Mihai Caraman <mihai.caraman@freescale.com>

The patch 08c9a188d0d0fc0f0c5e17d89a06bb59c493110f
  	kvm: powerpc: use caching attributes as per linux pte
do not handle properly the error case, letting mmu_lock locked. The lock
will further generate a RCU stall from kvmppc_e500_emul_tlbwe() caller.

In case of an error go to out label.

[PULL 2/6] KVM: PPC: BOOK3S: HV: Use base page size when comparing against slb value

[Alexander Graf]

From: "Aneesh Kumar K.V" <aneesh.kumar@linux.vnet.ibm.com>

With guests supporting Multiple page size per segment (MPSS),
hpte_page_size returns the actual page size used. Add a new function to
return base page size and use that to compare against the the page size
calculated from SLB. Without this patch a hpte lookup can fail since
we are comparing wrong page size in kvmppc_hv_find_lock_hpte.

[PULL 3/6] PPC: Add _GLOBAL_TOC for 32bit

[Alexander Graf]

Commit ac5a8ee8 started using _GLOBAL_TOC on ppc32 code. Unfortunately it's only
defined for 64bit targets though. Define it for ppc32 as well, fixing the build
breakage that commit introduced.

[PULL 4/6] KVM: PPC: Assembly functions exported to modules need _GLOBAL_TOC()

[Alexander Graf]

From: Anton Blanchard <anton@samba.org>

Both kvmppc_hv_entry_trampoline and kvmppc_entry_trampoline are
assembly functions that are exported to modules and also require
a valid r2.

As such we need to use _GLOBAL_TOC so we provide a global entry
point that establishes the TOC (r2).

[PULL 5/6] KVM: PPC: Book3S PR: Fix ABIv2 on LE

[Alexander Graf]

We switched to ABIv2 on Little Endian systems now which gets rid of the
dotted function names. Branch to the actual functions when we see such
a system.

[PULL 6/6] KVM: PPC: RTAS: Do byte swaps explicitly

[Alexander Graf]

In commit b59d9d26b we introduced implicit byte swaps for RTAS calls.
Unfortunately we messed up and didn't swizzle return values properly.

Also the old approach wasn't "sparse" compatible - we were randomly
reading __be32 values on an LE system.

Let's just do all of the swizzling explicitly with byte swaps right
where values get used. That way we can at least catch bugs using sparse.

This patch fixes XICS RTAS emulation on little endian hosts for me.

Thanks, pulled.

Pushing to kvm.git will have to wait for Autotesting of Bandan's nested
