tools headers arm64: Sync arm64's cputype.h with the kernel sources
To get the changes in:
924725707d80bc25 ("arm64: cputype: Add Neoverse-N3 definitions")
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_N3, that probably need
changes 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."
That addresses this perf build warning:
Warning: Kernel ABI header differences:
