Instead of having each architecture do it individually, we
do this in the arch-independent code (just x86 as of now).

This is a little more accurate (since it counts actual reloads, not potential
reloads), and reverses the sense of the statistic to measure a bad event like
most of the other stats (e.g. we want to minimize all counters).

We pass vcpu, vmx->fail, and vmx->launched to assembly code, but all three

This changes kvm_write_guest_page/kvm_read_guest_page to use
copy_to_user/read_from_user, as a result we get better speed
and better dirty bit tracking.

If vmx fails to inject a real-mode interrupt while fetching the interrupt
redirection table, it fails to record this in the vectoring information
field. So we detect this condition and do it ourselves.

We'll want to write to it in order to fix real-mode irq injection problems,
but it is a read-only field. Storing it in a variable solves that issue.
Signed-off-by: Avi Kivity <[email protected]>
Instead of injecting real-mode interrupts by writing the interrupt frame into
guest memory, abuse vmx by injecting a software interrupt. We need to
pretend the software interrupt instruction had a length > 0, so we have to
adjust rip backward.
This lets us not to mess with writing guest memory, which is complex and also
sleeps.
