* Major refactoring of the CPU capability detection logic resulting in the removal of the cpus_have_const_cap() function and migrating the code to "alternative" branches where possible * Backtrace/kgdb: use IPIs and pseudo-NMI * Perf and PMU: - Add support for Ampere SoC PMUs - Multi-DTC improvements for larger CMN configurations with multiple Debug & Trace Controllers - Rework the Arm CoreSight PMU driver to allow separate registration of vendor backend modules - Fixes: add missing MODULE_DEVICE_TABLE to the amlogic perf driver; use device_get_match_data() in the xgene driver; fix NULL pointer dereference in the hisi driver caused by calling cpuhp_state_remove_instance(); use-after-free in the hisi driver * HWCAP updates: - FEAT_SVE_B16B16 (BFloat16) - FEAT_LRCPC3 (release consistency model) - FEAT_LSE128 (128-bit atomic instructions) * SVE: remove a couple of pseudo registers from the cpufeature code. There is logic in place already to detect mismatched SVE features * Miscellaneous: - Reduce the default swiotlb size (currently 64MB) if no ZONE_DMA bouncing is needed. The buffer is still required for small kmalloc() buffers - Fix module PLT counting with !RANDOMIZE_BASE - Restrict CPU_BIG_ENDIAN to LLVM IAS 15.x or newer move synchronisation code out of the set_ptes() loop - More compact cpufeature displaying enabled cores - Kselftest updates for the new CPU features -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE5RElWfyWxS+3PLO2a9axLQDIXvEFAmU7/QUACgkQa9axLQDI XvEx3xAAjICmHm+ryKJxS1IGXLYu2DXMcHUjeW6w1SxkK/vKhTMlHRx/CIWDze2l eENu7TcDLtTw+Gv9kqg30TSwzLfJhP9oFpX2T5TKkh5qlJlbz8fBtm+as14DTLCZ p2sra3J0w4B5JwTVqnj2RHOlEftMKvbyLGRkz3ve6wIUbsp5pXMkxAd/k3wOf0lC m6d9w1OMA2sOsw9YCgjcCNQGEzFMJk+13w7K+4w6A8Djn/Jxkt4fAFVn2ZlCiZzD NA2lTDWJqGmeGHo3iFdCTensWXmWTqjzxsNEf7PyBk5mBOdzDVxlTfEL7vnJg7gf BlTQ/nhIpra7rHQ9q2rwqEzbF+4Tn3uWlQfdDb7+/4goPjDh7tlBhEOYyOwTCEIT 0t9cCSvBmSCKeXC3lKWWtJ+QJKhZHSmXN84EotTs65KyyfIsi4RuSezvV/+aIL86 06sHYlYxETuujZP1cgOjf69Wsdsgizx0mqXJXf/xOjp22HFDcL4Bki6Rgi6t5OZj GEHG15kSE+eJ+RIpxpuAN8fdrlxYubsVLIksCqK7cZf9zXbQGIlifKAIrYiEx6kz FD+o+j/5niRWR6yJZCtCcGxqpSlwnYWPqc1Ds0GES8A/BphWMPozXUAZ0ll4Fnp1 yyR2/Due/eBsCNESn579kP8989rashubB8vxvdx2fcWVtLC7VgE= =QaEo -----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: "No major architecture features this time around, just some new HWCAP definitions, support for the Ampere SoC PMUs and a few fixes/cleanups.
