Linus Torvalds 3cd86a58f7 arm64 updates for 5.7: ... - In-kernel Pointer Authentication support (previously only offered to user space). - ARM Activity Monitors (AMU) extension support allowing better CPU utilisation numbers for the scheduler (frequency invariance). - Memory hot-remove support for arm64. - Lots of asm annotations (SYM_*) in preparation for the in-kernel Branch Target Identification (BTI) support. - arm64 perf updates: ARMv8.5-PMU 64-bit counters, refactoring the PMU init callbacks, support for new DT compatibles. - IPv6 header checksum optimisation. - Fixes: SDEI (software delegated exception interface) double-lock on hibernate with shared events. - Minor clean-ups and refactoring: cpu_ops accessor, cpu_do_switch_mm() converted to C, cpufeature finalisation helper. - sys_mremap() comment explaining the asymmetric address untagging behaviour. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE5RElWfyWxS+3PLO2a9axLQDIXvEFAl6DVyIACgkQa9axLQDI XvHkqRAAiZA2EYKiQL4M1DJ1cNTADjT7xKX9+UtYBXj7GMVhgVWdunpHVE6qtfgk cT6avmKrS/6PDqizJgr+Z1yX8x3Kvs57G4BvmIUKIw97mkdewvFQ9JKv6VA1vb86 7Qrl1WzqsGg5Kj9uUfI4h+ZoT1H4C/9PQeFxJwgZRtF9DxRh8O7VeZI+JCu8Aub2 lIkjI8rh+EpTsGT9h/PMGWUcawnKQloZ1/F+GfMAuYBvIv2RNN2xVreJtTmm4NyJ VcpL0KCNyAI2lGdaJg5nBLRDyGuXDm5i+PLsCSXMquI4fie00txXeD8sjbeuO0ks YTJ0EhmUUhbSE17go+SxYiEFE0v09i+lD5ud+B4Vmojp0KTczTta9VSgURlbb2/9 n9biq5G3PPDNIrZqiTT2Tf4AMz1350nkbzL2gzKecM5aIzR/u3y5yII5CgfZtFnj 7bGbyFpFpcqI7UaISPsNCxmknbTt/7ff0WM3+7SbecxI3AD2mnxsOdN9JTLyhDp+ owjyiaWxl5zMWF9DhplLG/9BKpNWSxh3skazdOdELd8GTq2MbJlXrVG2XgXTAOh3 y1s6RQrfw8zXh8TSqdmmzauComXIRWTum/sbVB3U8Z3AUsIeq/NTSbN5X9JyIbOP HOabhlVhhkI6omN1grqPX4jwUiZLZoNfn7Ez4q71549KVK/uBtA= =LJVX -----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: "The bulk is in-kernel pointer authentication, activity monitors and lots of asm symbol annotations.
