Subject: [PATCH v1 1/1] EDAC, {skx,i10nm}: Use CPU stepping macro to pass configurations
Date: Sat,  9 May 2020 09:08:22 +0800	[thread overview]
Message-ID: <20200509010822.76331-1-qiuxu.zhuo@intel.com> (raw)

Use the X86_MATCH_INTEL_FAM6_MODEL_STEPPINGS() macro to pass CPU
stepping specific configurations to {skx,i10nm}_init(), so can delete
the CPU stepping check from 10nm_init().
