Hi all, This revision is based the following branch: https://git.kernel.org/pub/scm/linux/kernel/git/bp/bp.git/log/?h=tip-x86-misc The only major change from the branch is in patch 6. ("x86/amd_nb: Use topology info to get AMD node count") A check is added to verify that all nodes have a 'misc' device. This is to catch any unexpected system configurations including running inside a virtual guest where the node devices aren't exposed. The commit message is also updated. Thanks, Yazen Link: https://lore.kernel.org/r/20241206161210.163701-1-yazen.ghannam@xxxxxxx Major changes v2->v3: * Based on public branch from Boris. * Add check for not finding any 'misc' devices during init. v1->v2: * Rebase HSMP changes on latest upstream rework. * Keep Node and SMN code together.
