The following changes since commit ad81f0545ef01ea651886dddac4bef6cec930092:

Merge tag 'kvm-arm-for-3.12' of git://git.linaro.org/people/cdall/linux-kvm-arm into queue (2013-09-01 10:48:18 +0300)

The highlights of the release are nested EPT and pv-ticketlocks support
(hypervisor part, guest part, which is most of the code, goes through tip tree).
Apart of that there are many fixes for all arches.

This pull request adds tlb_gather_mmu() caller in S390 code, but 2b047252
in your tree added another parameter to the function, so the patch bellow
have to be applied during merge to resolve the conflicts. The patch was
used in linux-next for awhile.

Subject: [PATCH] s390: fix tlb_gather_mmu fallout

With commit 2b047252 "Fix TLB gather virtual address range invalidation
corner cases" tlb_gather_mmu() got a new argument.
There is however a patch in the kvm/linux-next tree "KVM: s390: allow sie
enablement for multi-threaded programs" which now causes breakage in
linux-next:

arch/s390/mm/pgtable.c: In function ‘s390_enable_sie’:
arch/s390/mm/pgtable.c:1175:2: error: too few arguments to function ‘tlb_gather_mmu’

So let's fix just this.
