Alexander Graf c8a73f186b KVM: SVM: Add microcode patch level dummy
VMware ESX checks if the microcode level is correct when using a barcelona
CPU, in order to see if it actually can use SVM. Let's tell it we're on the
safe side...

After the rewrite of KVM's debug support, this code doesn't even build any
more.

Avi Kivity 8b3079a5c0 KVM: VMX: When emulating on invalid vmx state, don't return to userspace unnecessarily
If we aren't doing mmio there's no need to exit to userspace (which will
just be confused).

Avi Kivity 350f69dcd1 KVM: x86 emulator: Make emulate_pop() a little more generic
Allow emulate_pop() to read into arbitrary memory rather than just the
source operand.  Needed for complicated instructions like far returns.

Avi Kivity 10f32d84c7 KVM: VMX: Prevent exit handler from running if emulating due to invalid state
If we've just emulated an instruction, we won't have any valid exit
reason and associated information.

Fix by moving the clearing of the emulation_required flag to the exit handler.
This way the exit handler can notice that we've been emulating and abort
early.

So that the auto-load mechanism can work on E500 when write a tlb entry.

Hollis Blanchard d0c7dc0344 KVM: ppc: split out common Book E instruction emulation
The Book E code will be shared with e500.

I've left PID in kvmppc_core_emulate_op() just so that we don't need to move
kvmppc_set_pid() right now. Once we have the e500 implementation, we can
probably share that too.
