[PULL 17/20] Revert "hw/i386: Update structures to save the number of nodes per package" |
Date: |
Wed, 2 Sep 2020 07:53:20 -0400 |
From: Babu Moger <babu.moger@amd.com>
This reverts commit c24a41bb53c0854d22c96b30d57cfcaa543c409d.
Remove the EPYC specific apicid decoding and use the generic
default decoding.
