The kernel provides infrastructure to set or clear the encryption mask from the pages for AMD SEV, but TDX requires few tweaks. - TDX and SEV have different requirements to the cache and TLB flushing. - TDX has own routine to notify VMM about page encryption status change. Modify __set_memory_enc_pgtable() and make it flexible enough to cover both AMD SEV and Intel TDX. The AMD-specific behavior is isolated in the callbacks under x86_platform.guest. TDX will provide own version of said callbacks. [ bp: Beat into submission. ] Signed-off-by: Brijesh Singh <brijesh.singh@amd.com> Signed-off-by: Borislav Petkov <bp@suse.de> Acked-by: Kirill A.
