Subject[PATCH 0/6] kvm: Emulate MOVBE, v3
Date
From: Borislav Petkov <bp@suse.de>

Alriiight,

here's another version of the patchset, hopefully addressing all review
feedback from last time. 6/6 is the respective qemu patch to handle
emulated features query, etc.

It is still a lot of fun to generate fast! Atom 32-bit SMP guests like
this:

[ 0.022876] ..TIMER: vector=0x30 apic1=0 pin1=2 apic2=-1 pin2=-1
[ 0.033304] smpboot: CPU0: Intel(R) Atom(TM) CPU N270 @ 1.60GHz (fam: 06, model: 1c, stepping: 02)
[ 0.037000] APIC calibration not consistent with PM-Timer: 146ms instead of 100ms
[ 0.037000] APIC delta adjusted to PM-Timer: 6249937 (9125627)
[ 0.037066] Performance Events: unsupported p6 CPU model 28 no PMU driver, software events only.

LooL :-)

Comments and suggestions appreciated, as always!

Thanks.
