    Subject[PATCH v6 0/6] Support TDX guests on Hyper-V
    Date
    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.
