ACPI: * Improve error reporting when failing to manage SDEI on AGDI device removal Assembly routines: * Improve register constraints so that the compiler can make use of the zero register instead of moving an immediate #0 into a GPR * Allow the compiler to allocate the registers used for CAS instructions CPU features and system registers: * Cleanups to the way in which CPU features are identified from the ID register fields * Extend system register definition generation to handle Enum types when defining shared register fields * Generate definitions for new _EL2 registers and add new fields for ID_AA64PFR1_EL1 * Allow SVE to be disabled separately from SME on the kernel command-line Tracing: * Support for "direct calls" in ftrace, which enables BPF tracing for arm64 Kdump: * Don't bother unmapping the crashkernel from the linear mapping, which then allows us to use huge (block) mappings and reduce TLB pressure when a crashkernel is loaded. Memory management: * Try again to remove data cache invalidation from the coherent DMA allocation path * Simplify the fixmap code by mapping at page granularity * Allow the kfence pool to be allocated early, preventing the rest of the linear mapping from being forced to page granularity Perf and PMU: * Move CPU PMU code out to drivers/perf/ where it can be reused by the 32-bit ARM architecture when running on ARMv8 CPUs * Fix race between CPU PMU probing and pKVM host de-privilege * Add support for Apple M2 CPU PMU * Adjust the generic PERF_COUNT_HW_BRANCH_INSTRUCTIONS event dynamically, depending on what the CPU actually supports * Minor fixes and cleanups to system PMU drivers Stack tracing: * Use the XPACLRI instruction to strip PAC from pointers, rather than rolling our own function in C * Remove redundant PAC removal for toolchains that handle this in their builtins * Make backtracing more resilient in the face of instrumentation Miscellaneous: * Fix single-step with KGDB * Remove harmless warning when 'nokaslr' is passed on the kernel command-line * Minor fixes and cleanups across the board -----BEGIN PGP SIGNATURE----- iQFEBAABCgAuFiEEPxTL6PPUbjXGY88ct6xw3ITBYzQFAmRChcwQHHdpbGxAa2Vy bmVsLm9yZwAKCRC3rHDchMFjNCgBCADFvkYY9ESztSnd3EpiMbbAzgRCQBiA5H7U F2Wc+hIWgeAeUEttSH22+F16r6Jb0gbaDvsuhtN2W/rwQhKNbCU0MaUME05MPmg2 AOp+RZb2vdT5i5S5dC6ZM6G3T6u9O78LBWv2JWBdd6RIybamEn+RL00ep2WAduH7 n1FgTbsKgnbScD2qd4K1ejZ1W/BQMwYulkNpyTsmCIijXM12lkzFlxWnMtky3uhR POpawcIZzXvWI02QAX+SIdynGChQV3VP+dh9GuFbt7ASigDEhgunvfUYhZNSaqf4 +/q0O8toCtmQJBUhF0DEDSB5T8SOz5v9CKxKuwfaX6Trq0ixFQpZ =78L9 -----END PGP SIGNATURE----- Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull arm64 updates from Will Deacon: "ACPI: - Improve error reporting when failing to manage SDEI on AGDI device removal Assembly routines: - Improve register constraints so that the compiler can make use of the zero register instead of moving an immediate #0 into a GPR - Allow the compiler to allocate the registers used for CAS instructions CPU features and system registers: - Cleanups to the way in which CPU features are identified from the ID register fields - Extend system register definition generation to handle Enum types when defining shared register fields - Generate definitions for new _EL2 registers and add new fields for ID_AA64PFR1_EL1 - Allow SVE to be disabled separately from SME on the kernel command-line Tracing: - Support for "direct calls" in ftrace, which enables BPF tracing for arm64 Kdump: - Don't bother unmapping the crashkernel from the linear mapping, which then allows us to use huge (block) mappings and reduce TLB pressure when a crashkernel is loaded.
