kvm: x86: Align kvm_arch_put_registers code with comment

The ordering doesn't matter in this case, but better keep it consistent.

kvm: x86: Prepare kvm_get_mp_state for in-kernel irqchip

This code path will not yet be taken as we still lack in-kernel irqchip
support. But qemu-kvm can already make use of it and drop its own
mp_state access services.

kvm: x86: Remove redundant mp_state initialization

kvm_arch_reset_vcpu initializes mp_state, and that function is invoked
right after kvm_arch_init_vcpu.

kvm: x86: Fix xcr0 reset mismerge

For unknown reasons, xcr0 reset ended up in kvm_arch_update_guest_debug
on upstream merge. Fix this and also remove the misleading comment (1 is
THE reset value).

kvm: x86: Swallow KVM_EXIT_SET_TPR

This exit only triggers activity in the common exit path, but we should
accept it in order to be able to detect unknown exit types.

kvm: Stop on all fatal exit reasons

Ensure that we stop the guest whenever we face a fatal or unknown exit
reason. If we stop, we also have to enforce a cpu loop exit.

kvm: Improve reporting of fatal errors

Report KVM_EXIT_UNKNOWN, KVM_EXIT_FAIL_ENTRY, and KVM_EXIT_EXCEPTION
with more details to stderr. The latter two are so far x86-only, so move
them into the arch-specific handler. Integrate the Intel real mode
warning on KVM_EXIT_FAIL_ENTRY that qemu-kvm carries, but actually...

x86: Optionally dump code bytes on cpu_dump_state

Introduce the cpu_dump_state flag CPU_DUMP_CODE and implement it for
x86. This writes out the code bytes around the current instruction
pointer. Make use of this feature in KVM to help debugging fatal vm
exits....

kvm: x86: Prevent sign extension of DR7 in guest debugging mode

This unbreaks guest debugging when the 4th hardware breakpoint used for
guest debugging is a watchpoint of 4 or 8 byte lenght. The 31st bit of
DR7 is set in that case and used to cause a sign extension to the high...
