Linus Torvalds 6e5772c8d9 Add an interface called cc_platform_has() which is supposed to be used 
by confidential computing solutions to query different aspects of the
 system. The intent behind it is to unify testing of such aspects instead
 of having each confidential computing solution add its own set of tests
 to code paths in the kernel, leading to an unwieldy mess.
