Right now sregs is unused on PPC, so we can use it for initialization

KVM on BookE always virtualizes the host CPU. On Book3s we go a

Following S390's good example we should use hrtimers for the decrementer too!
This patch converts the timer from the old mechanism to hrtimers.

For KVM we need to allocate a new context id, but don't really care about
all the mm context around it.
So let's split the alloc and destroy functions for the context id, so we can
grab one without allocating an mm context.

There are generic parts of PowerPC that can be shared across all
implementations and specific parts that only apply to BookE or desktop PPCs.
This patch adds emulation for desktop specific opcodes that don't apply

v3 - v4:
- use context_id instead of mm_context
v4 - v5:
- always include pvr in vcpu struct
of the guest's SLB in the PACA, switch to that on
entry and only restore bolted entries on exit, leaving the rest to the
Linux SLB fault handler.
That way we get a really clean way of switching the SLB.

KVM for PowerPC only supports embedded cores at the moment.
While it makes sense to virtualize on small machines, it's even more
fun
to do so on big boxes. So I figured we need KVM for PowerPC64 as well.

It looks like the variable pc is defined. At least the current code always
failed on me stating that pc is already defined somewhere else.
Let's use _pc instead, because that doesn't collide.
Is this the right approach? Does it break on 440 too? If not, why not?
