kvm: Align kvm_arch_handle_exit to kvm_cpu_exec changes

Make the return code of kvm_arch_handle_exit directly usable for
kvm_cpu_exec. This is straightforward for x86 and ppc, just s390
would require more work. Avoid this for now by pushing the return code...

kvm: x86: Do not leave halt if interrupts are disabled

When an external interrupt is pending but IF is cleared, we must not
leave the halt state prematurely.

x86: Properly reset PAT MSR

Conforming to the Intel spec, set the power-on value of PAT also on
reset, but save it across INIT.

kvm: x86: Consolidate TCG and KVM MCE injection code

This switches KVM's MCE injection path to cpu_x86_inject_mce, both for
SIGBUS and monitor initiated events. This means we prepare the MCA MSRs
in the VCPUState also for KVM.

We have to drop the MSRs writeback restrictions for this purpose which...

kvm: x86: Clean up kvm_setup_mce

There is nothing to abstract here. Fold kvm_setup_mce into its caller
and fix up the error reporting (return code of kvm_vcpu_ioctl holds the
error value).

kvm: x86: Fail kvm_arch_init_vcpu if MCE initialization fails

There is no reason to continue if the kernel claims to support MCE but
then fails to process our request.

KVM, MCE, unpoison memory address across reboot

In Linux kernel HWPoison processing implementation, the virtual
address in processes mapping the error physical memory page is marked
as HWPoison. So that, the further accessing to the virtual
address will kill corresponding processes with SIGBUS....

x86: Run qemu_inject_x86_mce on target VCPU

We will use the current TCG-only MCE injection path for KVM as well, and
then this read-modify-write of the target VCPU state has to be performed
synchronously in the corresponding thread.
