[GIT PULL 00/51] KVM/ARM updates for 3.17

[Christoffer Dall]

Hi Paolo and Gleb,

The following changes since commit 9f6226a762c7ae02f6a23a3d4fc552dafa57ea23:

  arch: x86: kvm: x86.c: Cleaning up variable is set more than once (2014-06-30 16:52:04 +0200)

are available in the git repository at:

  git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm.git tags/kvm-arm-for-3.17

for you to fetch changes up to dedf97e8ff2c7513b1370e36b56e08b6bd0f0290:

  arm64: KVM: fix 64bit CP15 VM access for 32bit guests (2014-08-01 14:05:06 +0200)

Please note that there are two dependencies for this series:
  021f653 (deps-irqchip-gic-3.17) from Jason Cooper
  72c5839 (Allow GICv3 compilation with older binutils) from Catalin

These should both go in when the arm64 tree lands in Linus' tree.  We
will let you know.

Also note that merging these changes are likely to result in a somewhat
non-trivial merge conflict.  We have provided a conflict resolution
branch here with the correct merge result:
  git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm.git conflict-resolution-for-linus
  commit: 19690a1119a0 (the top one)

Can you pass this on to Linus?


Thanks,
Marc & Christoffer

----------------------------------------------------------------
KVM/ARM New features for 3.17 include:
 - Fixes and code refactoring for stage2 kvm MMU unmap_range
 - Support unmapping IPAs on deleting memslots for arm and arm64
 - Support MMIO mappings in stage2 faults
 - KVM VGIC v2 emulation on GICv3 hardware
 - Big-Endian support for arm/arm64 (guest and host)
 - Debug Architecture support for arm64 (arm32 is on Christoffer's todo list)
 - Detect non page-aligned GICV regions and bail out (plugs guest-can-crash host bug)
