With EPT enabled it is not required to explicitly run invvpid to invalidate
tagged TLB entries, as
KVM does not force vm-exits for cr3 writes and invlpg. Run invvpid only when
these instructions
are emulated and shadow pages are used.

When running kvm_vcpu_block and it realizes that the CPU is actually good
to run, we get a request bit set for KVM_REQ_UNHALT. Right now, there's
nothing we can do with that bit, so let's unset it right after the call
again so we don't get confused in our later checks for pending work.

When running PR KVM on a p7 system in bare metal, we get HV exits instead
of normal supervisor traps. Semantically they are identical though and the
HSRR vs SRR difference is already taken care of in the exit code.
So all we need to do is handle them in addition to our normal exits.

Hi,
I'm a KVM user, using it for the first time and so far very happy
with it.
I wonder if someone can help me get my head round the issue of balloon
memory and overallocation.
Basically I have a Debian wheezy/sid KVM server, on which I have a
couple of Linux guests and several FreeBSD gue

As kvm_notify_acked_irq calls kvm_assigned_dev_ack_irq under
rcu_read_lock, we cannot use a mutex in the latter function. Switch to a
spin lock to address this.
