Hi All,

Intel's Trust Domain Extensions (TDX) protect guest VMs from malicious
hosts and some physical attacks.

Following patches adds tracepoint support for TDX Guest TDCALL requests
and #VE exceptions. It also includes helper function to detect TD-DEBUG
mode which will be used by patches in other TDX series to add TD-DEBUG
mode specific features support.

This series is the continuation of the following TDX guest related patches.

[set 1] - https://lore.kernel.org/patchwork/project/lkml/list/?series=508773
[set 2] - https://lore.kernel.org/patchwork/project/lkml/list/?series=508792
[set 3] - https://lore.kernel.org/patchwork/project/lkml/list/?series=508794
[set 4] - https://lore.kernel.org/patchwork/project/lkml/list/?series=508795

Also please note that this series alone is not necessarily fully
functional. You need to apply all the above 4 patch series to get 
a fully functional TDX guest.

Changes since v1:
 * Rebased on top of v5.14-rc1.
