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. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEzv7L6UO9uDPlPSfHEsHwGGHeVUoFAmF/uLUACgkQEsHwGGHe VUqGbQ/+LOmz8hmL5vtbXw/lVonCSBRKI2KVefnN2VtQ3rjtCq8HlNoq/hAdi15O WntABFV8u4daNAcssp+H/p+c8Mt/NzQa60TRooC5ZIynSOCj4oZQxTWjcnR4Qxrf oABy4sp09zNW31qExtTVTwPC/Ejzv4hA0Vqt9TLQOSxp7oYVYKeDJNp79VJK64Yz Ky7epgg8Pauk0tAT76ATR4kyy9PLGe4/Ry0bOtAptO4NShL1RyRgI0ywUmptJHSw FV/MnoexdAs4V8+4zPwyOkf8YMDnhbJcvFcr7Yd9AEz2q9Z1wKCgi1M3aZIoW8lV YMXECMGe9DfxmEJbnP5zbnL6eF32x+tbq+fK8Ye4V2fBucpWd27zkcTXjoP+Y+zH NLg+9QykR9QCH75YCOXcAg1Q5hSmc4DaWuJymKjT+W7MKs89ywjq+ybIBpLBHbQe uN9FM/CEKXx8nQwpNQc7mdUE5sZeCQ875028RaLbLx3/b6uwT6rBlNJfxl/uxmcZ iF1kG7Cx4uO+7G1a9EWgxtWiJQ8GiZO7PMCqEdwIymLIrlNksAk7nX2SXTuH5jIZ YDuBj/Xz2UUVWYFm88fV5c4ogiFlm9Jeo140Zua/BPdDJd2VOP013rYxzFE/rVSF SM2riJxCxkva8Fb+8TNiH42AMhPMSpUt1Nmd1H2rcEABRiT83Ow= =Na0U -----END PGP SIGNATURE----- Merge tag 'x86_cc_for_v5.16_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull generic confidential computing updates from Borislav Petkov: "Add an interface called cc_platform_has() which is supposed to be used by confidential computing solutions to query different aspects of the system.
