This series support Cortex-X4 CPU in Perf Arm SPE.
The Arm64 and tools both include the header cputype.h for CPU part and
MIDR definitions, to de-couple between the tools and the kernel, the
tools doesn't directly use the kernel's header, alternatively, the tools
maintain a copy and sync with kernel's header.
To keep the exact same content between kernel and tools' headers, this
series firstly adds Cortex-X4 CPU part and MIDR definitions in the
kernel header; then the second patch syncs the change into the tools'
header. The first patch is to support the Cortex-X4 in perf Arm SPE
with the new CPU definitions.
I don't have Cortex-X4 machine in hand, so just verified with
compilation perf tool.
