[Xen-devel] [PATCH] xen svm: fix PAUSE instruction intercept

[Christoph Egger <Christoph.Egger@xxxxxxx>]

Hi!

Attached patch moves PAUSE instruction intercept handling
into svm_vmexit_do_pause() analogous to the other instruction
intercepts.

In svm_vmexit_do_pause() update the instruction pointer.
This fixes strange PAUSE intercepts on UP guests.

Signed-off-by: Christoph Egger <Christoph.Egger@xxxxxxx>

P.S.: This bug has been found with nested virtualization.
