Hi Vladmir,

Thanks for your guidence to the better fix. I built your patch with
attach patch on top of yours to fix the errors found in our build
service and also some other affected platforms which might also need the
similar fix.

In the attatched patch, for i386-pc the acpi module was not built into
kernel because from your patch seems not use pmtimer on it. That would
be help in saving up the kernel image size.

I have tested on x86_64-efi and i386-pc and so far it works as expected.
Please note I also manually tweaked the patch to run pmtimer calibration
in efi and it also worked.

Thanks,
Michael
