Tested this on 2 AMD platforms that were not affected by the crash here.
In addition to confirming that they boot fine without timer complaints
in the logs, I checked the calibrate_APIC_clock() result before and
after this patch. I repeated each test twice.

Asus E402YA (AMD E2-7015)
Before: 99811, 99811
After: 99812, 99812

Acer Aspire A315-21G (AMD A9-9420e)
Before: 99811, 99811
After: 99807, 99820

Those new numbers seem very close to the previous ones and I didn't
observe any problems.

Thanks
Daniel
