[PATCH v2 0/5] TDX host: Provide TDX module metadata reading APIs

[Kai Huang <kai.huang@intel.com>]

KVM will need to read bunch of TDX module metadata fields to create and
run TDX guests.  In the long term, other in-kernel TDX users, e.g., VT-d
also likely will need to read metadata.  This series provides common APIs
in the TDX host code so that KVM can use.

v1 -> v2:
  - Collect BinBin's tag.
  - Rebase to latest Linus's tree (but can also be cleanly applied to 
    latest tip/master and tip/x86/tdx).

(I dropped KVM list from the To list to stop dumping emails to people's
 mailbox, but keep maintainers Cc'ed.)

v1: https://lore.kernel.org/lkml/cover.1709288433.git.kai.huang@intel.com/T/

Kai Huang (5):
  x86/virt/tdx: Rename _offset to _member for TD_SYSINFO_MAP() macro
  x86/virt/tdx: Move TDMR metadata fields map table to local variable
  x86/virt/tdx: Unbind global metadata read with 'struct
    tdx_tdmr_sysinfo'
  x86/virt/tdx: Support global metadata read for all element sizes
  x86/virt/tdx: Export global metadata read infrastructure
