[PULL 00/13] KVM/ARM Fixes for v4.12-rc2

[cdall@linaro.org (Christoffer Dall)]

Hi Radim and Paolo,

Here is a fairly large set of fixes post -rc1 for KVM/ARM.

The fixes include:
 - A fix for a build failure introduced in -rc1 when tracepoints are
   enabled on 32-bit ARM.
 - Disabling use of stack pointer protection in the hyp code which can
   cause panics.
 - A handful of VGIC fixes.
 - A fix to the init of the redistributors on GICv3 systems that
   prevented boot with kvmtool on GICv3 systems introduced in -rc1.
 - A number of race conditions fixed in our MMU handling code.
 - A fix for the guest being able to program the debug extensions for
   the host on the 32-bit side.

The following changes since commit 2ea659a9ef488125eb46da6eb571de5eae5c43f6:
