keep old userspace from breaking. Adjust the corresponding iopl selftest to that. - Improve stack overflow warnings to say which stack got overflowed and raise the exception stack sizes to 2 pages since overflowing the single page of exception stack is very easy to do nowadays with all the tracing machinery enabled. With that, rip out the custom mapping of AMD SEV's too. - A bunch of changes in preparation for FGKASLR like supporting more than 64K section headers in the relocs tool, correct ORC lookup table size to cover the whole kernel .text and other adjustments. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEzv7L6UO9uDPlPSfHEsHwGGHeVUoFAmF/uugACgkQEsHwGGHe VUroKw//e8BJ3Aun8bg00FHxfiMGbPYcozjLGDkaoMtMDZ8WlfCUrvtqYICEr8eB UU0eRyygAPI167dre1O9JvAcbilkNTKntaU6qbu/ZVyUwS3+Jkjwsotbqn3xKtkd QDDTDNiCU+beCJ2ZbspbrPgEh13+H0MwMHUfRxZB9Scpmo6aGSEaU3g295f6GX57 VFGJ/LNov5MV1dTD7Pp/h6/Nb+R6WmflKcBzJmQxYuKyKX+g1xsSv0VSga+t+uf3 M9pUkizqTiUxzC2eLgtcEZTqqBHu810E8M76FmhKBUMilsFJT5YAJTiqyahwHXds HYarOFRgcnFuJPd29vn8UHjqeeoi6ru8GtcZYzccEc7U3ku/gXPaDJ9ffmvhs7vU pJX5Um3GiiFm0w/ZZOKDqh78wRAsCKLN+jIoyszuhkkNchZSj/jKfOgdd3EmcZst 6L6rxBA4oRHwNOgM7uVMp+jFeRe1/prR280OWWH0D4QmmuqybThOdO23Iuh/Deth W3qPUH3UQtfSWxGy2yODzJ1ciuGAr/AzJZ9zjg04e3Vl0DkEpyWtLKJiG3ClXZag Nj+3xc4xYH2Aw+M0HRaONk5XVKLpqVjuAfgU5iLQa0YSUbtrR+wCWvY8KgQNbAqK xZmzYzQ89stwVCuGKx10gPsL3jSJ3VCylMfqdHD2Ajmld1yApr0= =DOZU -----END PGP SIGNATURE----- Merge tag 'x86_core_for_v5.16_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull x86 core updates from Borislav Petkov: - Do not #GP on userspace use of CLI/STI but pretend it was a NOP to keep old userspace from breaking.
