This series does some cleanup and precursor changes to the hyper-v clock source and introduces support for TSC page based clock in root partition.
Hyper-V root partition requires kernel to map the page, specified by the hypervisor (instead of provide the PFN to the hypervisor like it's done in guest partition).
v3: 1. Rebased on top of the fix to support arbitrary TSC page size by Anirudh 2. Fixed TSC physical page when remapping in root partition.
v2: 1. Addressed all the comments to the commit messages. 2. TSC page in root partition is now remapped based on size of the tsc_pg variable.
The following series implements...
