tools headers arm64: Sync arm64's cputype.h with the kernel sources
To get the changes in: db0d8a84348b876d ("arm64: errata: Enable the AC03_CPU_38 workaround for ampere1a") That makes this perf source code to be rebuilt: CC /tmp/build/perf-tools/util/arm-spe.o The changes in the above patch add MIDR_AMPERE1A, used in arm-spe.c, so probably we need to add it to that array? Or maybe we need to leave this for later when this is all tested on those machines? static const struct midr_range neoverse_spe[] = { MIDR_ALL_VERSIONS(MIDR_NEOVERSE_N1), MIDR_ALL_VERSIONS(MIDR_NEOVERSE_N2), MIDR_ALL_VERSIONS(MIDR_NEOVERSE_V1), {}, }; Mark Rutland recommended about arm-spe.c in a previous update to this file: "I would not touch this for now -- someone would have to go audit the TRMs to check that those other cores have the same encoding, and I think it'd be better to do that as a follow-up."
