Current code serialize mtrr init with set_atomicity_lock.
Mtrr init is quite slow when we bootup on a hvm with large mem, vcpus
and pci passthroughed devices(eg. 24 vcpus + 90G mem).
It took about ~30 mins to bootup, after patch, it took ~2 min.
When you're saying "HVM" do you mean "Xen HVM"? How does it behave on
native hardware?

Yes, I mean Xen HVM. Bootup at same speed as before on baremetal.
