Subject: [PATCH] cpu_map: Define and enable Snowridge model
7548c0
7548c0
Due to missing pdpe1gb support in the host CPU data, the CPU is still
7548c0
incorrectly detected as Westmere-IBRS for host capabilities because we
7548c0
don't have the option to disable features included in the base model
7548c0
there.
