[PATCH 4.15 068/202] [Variant 2/Spectre-v2] arm64: cputype: Add missing MIDR values for Cortex-A72 and Cortex-A75

[Greg Kroah-Hartman]

4.15-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Will Deacon <will.deacon@xxxxxxx>


Commit a65d219fe5dc upstream.

Hook up MIDR values for the Cortex-A72 and Cortex-A75 CPUs, since they
will soon need MIDR matches for hardening the branch predictor.
