[PULL 00/21] KVM/ARM Changes for v4.4-rc1

[Christoffer Dall]

Hi Paolo,

Here is the set of changes for v4.4.  Some of the commits listed here were
already merged as fixes for v4.3, but since they are not in kvm/next yet, they
show up here.  Let me know if you want me to handle this differently somehow.

As usual, there's a lot of churn in the vgic and timer code, and then there are
number of smaller tweaks and adjustments.  Nothing major this time around.  For
a detailed description, see below.

The following changes since commit 920552b213e3dc832a874b4e7ba29ecddbab31bc:

  KVM: disable halt_poll_ns as default for s390x (2015-09-25 10:31:30 +0200)

  KVM: arm/arm64: Merge vgic_set_lr() and vgic_sync_lr_elrsr() (2015-11-04 15:29:49 +0100)

KVM/ARM Changes for v4.4-rc1

Includes a number of fixes for the arch-timer, introducing proper
level-triggered semantics for the arch-timers, a series of patches to
synchronously halt a guest (prerequisite for IRQ forwarding), some tracepoint
improvements, a tweak for the EL2 panic handlers, some more VGIC cleanups
getting rid of redundant state, and finally a stylistic change that gets rid of
some ctags warnings.
