From db970bd231c2264a062e0de4dcf4ead5e6669e7a Mon Sep 17 00:00:00 2001 From: Yazen Ghannam Date: Mon, 9 Nov 2020 21:06:57 +0000 Subject: x86/CPU/AMD: Remove amd_get_nb_id() The Last Level Cache ID is returned by amd_get_nb_id(). In practice, this value is the same as the AMD NodeId for callers of this function. The NodeId is saved in struct cpuinfo_x86.cpu_die_id. Replace calls to amd_get_nb_id() with the logical CPU's cpu_die_id and remove the function.
