[PATCH 1/3] x86/mce/amd: apply MC4_MISC thresholding to all models of family 15

From: S, Shirish
Date: Thu Jan 10 2019 - 02:54:46 EST


Its evident from various forums and logs that MC4_MISC thresholding is not
supported for the family 15 processors, hence skip the x86_model check
while applying quirk.

Changelog[v2]:
- reword commit message to adhere to coding standards
- remove check of model range
