Kirill A. Shutemov 41394e33f3 x86/tdx: Extend the confidential computing API to support TDX guests ... Confidential Computing (CC) features (like string I/O unroll support, memory encryption/decryption support, etc) are conditionally enabled in the kernel using cc_platform_has() API. Since TDX guests also need to use these CC features, extend cc_platform_has() API and add TDX guest-specific CC attributes support. CC API also provides an interface to deal with encryption mask. Extend it to cover TDX. Details about which bit in the page table entry to be used to indicate shared/private state is determined by using the TDINFO TDCALL. Signed-off-by: Kirill A.
