From 6840a150b9daf35e4d21ab9780d0a03b4ed74a5b Mon Sep 17 00:00:00 2001 From: Mike Travis Date: Fri, 5 Mar 2021 10:28:53 -0600 Subject: [PATCH] x86/platform/uv: Set section block size for hubless architectures Commit bbbd2b51a2aa ("x86/platform/UV: Use new set memory block size function") added a call to set the block size value that is needed by the kernel to set the boundaries in the section list. This was done for UV Hubbed systems but missed in the UV Hubless setup. Fix that mistake by adding that same set call for hubless systems, which support the same NVRAMs and Intel BIOS, thus the same problem occurs.
