- In copy_highpage(), only reset the tag of the destination pointer if KASAN_HW_TAGS is enabled so that user-space MTE does not interfere with KASAN_SW_TAGS (which relies on top-byte-ignore). - Remove warning if SME is detected without SVE, the kernel can cope with such configuration (though none in the field currently). - In cfi_handler(), pass the ESR_EL1 value to die() for consistency with other die() callers. - Disable HUGETLB_PAGE_OPTIMIZE_VMEMMAP on arm64 since the pte manipulation from the generic vmemmap_remap_pte() does not follow the required ARM break-before-make sequence (clear the pte, flush the TLBs, set the new pte). It may be re-enabled once this sequence is sorted. - Fix possible memory leak in the arm64 ACPI code if the SMCCC version and conduit checks fail. - Forbid CALL_OPS with CC_OPTIMIZE_FOR_SIZE since gcc ignores -falign-functions=N with -Os. - Don't pretend KASLR is enabled if offset < MIN_KIMG_ALIGN as no randomisation would actually take place. -----BEGIN PGP SIGNATURE----- iQIyBAABCgAdFiEE5RElWfyWxS+3PLO2a9axLQDIXvEFAmQBHFEACgkQa9axLQDI XvHf9Q/3Zg8o/8HchnWSvzgV//9ljGrrDfAjbfZHrE2W4PCniSd0op0uXYsVK3IH Nk6ZDiRe5uIXKgHuSq5caOoL4aRk0hk1TpQ3RKCuh8E3ybhQe9gwYm8xEWXDSSWh QzcfENsKlZLpuMoSMILJ2NlMPMbMLprXNCUlgENBbRT7KUToHZKTwE6BL2AUI3tg RdMntccorybxk1hiXV1YKT8482i+x2gAnylYXFsq3eI+G54rdfiks+tft0CQV3ng 1/i1PfbnGC45sBoxXPqYXzBSUDNHpAqb5dwvtlVinGo3J6STxIvbM6Zi5Ma5hl3u QrhwyduwCTZ6wVOqzd4KAH9gmhJSzRG75OzCek2dTwU9KXVMOPEvp1ZfTwUXDx7J 5j8UkjGgrbtj6IioGqBAO/HiFfoty8EBtmlSZIj0thwxkM73ZBG6efQOJaVWh85m ioUzMC2Y5yfKLfHEcy9yKIQVizMYoz6fl+QHOEbVSoFhJKNRc4wt5CCJCvsbMHsu K8rvD/CI9jFMP9GEK7ObTaC7ICjUz/+8wbIrRrm5ObRQ65Tm2zv3OLqGnK8O5O4W gcDEraTnSPHDUtgG6dAEPFN5Wi9hT3zYC0xAcNhc3aZC5ofS5RD6YXIWJvqjWrvL 5k8G1gfa57C/hfxO6pPw7bg/nY8vvYpxUkZ9erRWD430g7y0Sg== =jfPa -----END PGP SIGNATURE----- Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull arm64 fixes from Catalin Marinas: - In copy_highpage(), only reset the tag of the destination pointer if KASAN_HW_TAGS is enabled so that user-space MTE does not interfere with KASAN_SW_TAGS (which relies on top-byte-ignore). - Remove warning if SME is detected without SVE, the kernel can cope with such configuration (though none in the field currently). - In cfi_handler(), pass the ESR_EL1 value to die() for consistency with other die() callers. - Disable HUGETLB_PAGE_OPTIMIZE_VMEMMAP on arm64 since the pte manipulation from the generic vmemmap_remap_pte() does not follow the required ARM break-before-make sequence (clear the pte, flush the TLBs, set the new pte).
