Description LeoLiu-oc zhaoxin_group 2024-06-25 18:28:08 UTC 
通过该补丁，使得内核默认可以通过BIOS设置CMCI threahold值。

In the Linux kernel, the CMCI threshold is set to 1 by default. This patch
prevents Linux from overwriting the CMCI threshold set by the bios. With
this patch, the CMCI threshold can be set through the BIOS, which can also
avoid CMCI storms, on Zhaoxin/Centaur CPUs.
