Subject: [PATCH v1 0/3] arm64: Support Cortex-X4 CPU for Perf Arm SPE
Date:   Mon, 17 Jul 2023 13:43:24 +0800

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.
