2022-02-23	x86/coco: Explicitly declare type of confidential computing platform	Kirill A. Shutemov	1	-12/+17
	The kernel derives the confidential computing platform type it is running as from sme_me_mask on AMD or by using hv_is_isolation_supported() on HyperV isolation VMs. This detection process will be more complicated as more platforms get added. Declare a confidential computing vendor variable explicitly and set it via cc_set_vendor() on the respective platform. [ bp: Massage commit message, fixup HyperV check. ] Signed-off-by: Kirill A.

2022-02-23	x86/cc: Move arch/x86/{kernel/cc_platform.c => coco/core.c}	Kirill A. Shutemov	2	-0/+91
	Move cc_platform.c to arch/x86/coco/. The directory is going to be the home space for code related to confidential computing. Intel TDX code will land here. AMD SEV code will also eventually be moved there. No functional changes. Signed-off-by: Kirill A.
