  The patchset adds the Hyper-V specific code so that a TDX guest can run
on Hyper-V. Please review.

The v6 patchset is based on today's mainline (a1fd058b07d5).

The v6 patchset addressed Michael's comments on patch 5:
  Removed 2 unnecessary lines of messages from the commit log.
  Fixed the error handling path for hv_synic_alloc()/free().
  Printed the 'ret' in hv_synic_alloc()/free().

@Michael Kelley: Can you please review patch 5?

@x86 maintainers:
  If the patches look good to you, can you please take patch 1 and 2
into the tip tree?
  
@Wei Liu: I think patch 3, 4, 5, 6 should go through the Hyper-V tree
since they change the Hyper-V code.

If you want to view the patches on github, it is here:
