+Subject: tools headers arm64: Sync arm64's cputype.h with the kernel sources
+
+From: Arnaldo Carvalho de Melo <acme@redhat.com>
+
+commit dc6abbbde4b099e936cd5428e196d86a5e119aae upstream.
+
+To get the changes in:
+
+  0ce85db6c2141b7f ("arm64: cputype: Add Neoverse-V3 definitions")
+  02a0a04676fa7796 ("arm64: cputype: Add Cortex-X4 definitions")
+  f4d9d9dcc70b96b5 ("arm64: Add Neoverse-V2 part")
+
+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_NEOVERSE_V[23] and
+MIDR_NEOVERSE_V1 is used in arm-spe.c, so probably we need to add those
+and perhaps MIDR_CORTEX_X4 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:
+
+"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."
+
+That addresses this perf build warning:
+
+  Warning: Kernel ABI header differences:
+    diff -u tools/arch/arm64/include/asm/cputype.h arch/arm64/include/asm/cputype.h
