x86, hyperv: Get the local APIC timer frequency from the hypervisor
Hyper-V supports a mechanism for retrieving the local APIC frequency.
Use this and bypass the calibration code in the kernel . This would
allow us to boot the Linux kernel as a "modern VM" on Hyper-V where
many of the legacy devices (such as PIT) are not emulated.
I would like to thank Olaf Hering <[email protected]>, Jan Beulich <[email protected]> and
H. Peter Anvin <[email protected]> for their help in this effort.
In this version of the patch, I have addressed Jan's comments.
