After some consideration I decided to submit only Hyper-V reference
counters support this time. I will submit iTSC support as a separate
patch as soon as it is ready.
v1 -> v2
1. mark TSC page dirty as suggested by
Eric Northup <digitaleric@google.com> and Gleb
2. disable local irq when calling get_kernel_ns,
as it was done by Peter Lieven <pl@amp.de>
3. move check for TSC page enable from second patch
to this one.
v3 -> v4
Get rid of ref counter offset.
v4 -> v5
replace __copy_to_user with kvm_write_guest
when updateing iTSC page.

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 <olaf@aepfle.de>, Jan Beulich <JBeulich@suse.com> and
H. Peter Anvin <h.peter.anvin@intel.com> for their help in this effort.
In this version of the patch, I have addressed Jan's comments.
