Add a facility to report on accesses to the local apic tpr even if the
local apic is emulated in the kernel. This is basically a hack that
allows userspace to patch Windows which tends to bang on the tpr a lot.

This adds a mechanism for exposing the virtual apic tpr to the guest, and a
protocol for letting the guest update the tpr without causing a vmexit if
conditions allow (e.g. there is no interrupt pending with a higher priority
than the new tpr).

When we emulate a guest pte write, we fail to apply the correct inherited
permissions from the parent ptes. Now that we store inherited permissions
in the shadow page, we can use that to update the pte permissions correctly.

With this patch KVM on SVM will exit to userspace if the guest writes to CR8
and the in-kernel APIC is disabled.

Unify the special instruction switch with the regular instruction switch,
and the two byte special instruction switch with the regular two byte
instruction switch. That makes it much easier to find an instruction or
the place an instruction needs to be added in.

As set_pte() no longer references either a gpte or the guest walker, we can
move it out of paging mode dependent code (which compiles twice and is
generally nasty).

Thanks, I merged your fix into the patch.

error compiling committee.c: too many arguments to function
Since gfn_to_page() is a sleeping function, and we want to make the core mmu
spinlocked, we need to pass the page from the walker context (which can sleep)
to the shadow context (which cannot).

Convert the synchronization of the shadow handling to a separate mmu_lock
spinlock.
Also guard fetch() by mmap_sem in read-mode to protect against alias
and memslot changes.
