| Subject: x86/platform/uv: Set section block size for hubless architectures |
| |
| From: Mike Travis <mike.travis@hpe.com> |

| [ Upstream commit 6840a150b9daf35e4d21ab9780d0a03b4ed74a5b ] |

| |
| 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. |
