Using yout vmexit.flat, it can work with my patch smoothly. Is
this the one you see problems?

I was thinking about some of the issues that we are dealing with
w.r.t. signalling a sleeping userspace (eventfd, signals, etc). I was
wondering if perhaps we were looking at the problem the wrong way. Can we
perform halts in the kernel and therefore eliminate the need to signa

This patch is to avoid saving and restoring of msr_efer on
lightweight vmexit.
With this patch, the Kernel build get 10% increasement for
64bits on 64 bits,
and 5-8% increasement for 32bits on 64 bits.
Vmexit.flat can see ~1185 cycles save for 64 bits on 64 bi

Avi,
I assume you mean the "v4 & v5" acpi patches from Gregory Haskins,
sorry to ask a seemingly simple question, but I'm new to the list.
Also, I don't have these patches
