Linus Torvalds 9b9e211360 arm64 updates for 5.17: ... - KCSAN enabled for arm64. - Additional kselftests to exercise the syscall ABI w.r.t. SVE/FPSIMD. - Some more SVE clean-ups and refactoring in preparation for SME support (scalable matrix extensions). - BTI clean-ups (SYM_FUNC macros etc.) - arm64 atomics clean-up and codegen improvements. - HWCAPs for FEAT_AFP (alternate floating point behaviour) and FEAT_RPRESS (increased precision of reciprocal estimate and reciprocal square root estimate). - Use SHA3 instructions to speed-up XOR. - arm64 unwind code refactoring/unification. - Avoid DC (data cache maintenance) instructions when DCZID_EL0.DZP == 1 (potentially set by a hypervisor; user-space already does this). - Perf updates for arm64: support for CI-700, HiSilicon PCIe PMU, Marvell CN10K LLC-TAD PMU, miscellaneous clean-ups. - Other fixes and clean-ups; highlights: fix the handling of erratum 1418040, correct the calculation of the nomap region boundaries, introduce io_stop_wc() mapped to the new DGH instruction (data gathering hint). -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE5RElWfyWxS+3PLO2a9axLQDIXvEFAmHXNtYACgkQa9axLQDI XvHBGw/+OVGdbORxwrU+uRb7N6qIJkrW/mmM4x1KLo1i+REZLb8/VlXm0xC60FG+ 39x6FSVkRr+lLDfTqpQsOez5FpdsvOe9Fc4L3bwniDg+EPo7x65VmP2dw/Ae2q0i 87xyWCczx5hFEPF/1sb1R1pm3bTXjeklBkdv+OXhwflLOwpCp1J8z8WJK8qJVFX6 CmuE6Q4fDQr0ghl9Nf8DiAr20mHDh8wMKNUJOg4waaQOOCta6q1oJ3qfz6E9z1eW zEE3dfZgBCx7HCRc3KGgzT7H4Ces3BYvhBYP6bJRliVI88XdPiM4MfdGL4UIb27Q NLAdr+FVzk/YLzMHtxSfkT10nBqoOPWUTckLu9jIIl5cpBX73Wiz7jfzBvqFmC/y opSFMZ3lwQPM5WAPtAlZptA3GPPySeInVmvUgB7IQ+1Q1T1n8ri1y5hzTYC4Sc/g amJI1rXf1Al8+2zFBggr6Up+EOnfV9nAwrzLXkRlASsfmvY4dnVWg3NWfBqtEHAq VuZCecSgawxuSlpmJ4VGbLrBFaz18bn9EzujR5fFvi5Qcg1CMFOROi2+6IynopNV IS0R8j6fwgQPA5lcnNIPeJRRkQoqO4l8bPDzeXEny0BSw313EgBSo9aQtnjyIJbp BTuDHARKs+/NvDPvd8GQkxNPgwJnVOL9pdgNAolEu1/k7JtnIS0= =ecyi -----END PGP SIGNATURE----- Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull arm64 updates from Catalin Marinas: - KCSAN enabled for arm64. - Additional kselftests to exercise the syscall ABI w.r.t.
