Subject: [Variant 2/Spectre-v2] arm64: cputype: Add missing MIDR values for Cortex-A72 and Cortex-A75
From: Will Deacon <will.deacon@arm.com>
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.
