Subject: [PATCH] x86-64: Remove code to resume machine check state of other CPUs.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=413588c7cb8113c03d0044f1d41b832ad7201c29;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[PATCH] x86-64: Remove code to resume machine check state of other CPUs.

The resume code uses CPU hotplug now so at resume time
we only ever see one CPU.

Pointed out by Yu Luming.
