I'll be running the tests this afternoon. But I'm somewhat confident that they will pass.

Tree is here: git://git.kernel.org/pub/scm/linux/kernel/git/aegl/linux.git branch "hopeful_snc"

Commits are:

793635f10aeb x86/resctrl: Update documentation with Sub-NUMA cluster changes
dca7ba785d6f x86/resctrl: Sub NUMA Cluster detection and enable

5699cd082e1f x86/resctrl: Remove hard-coded memory bandwidth limit
1b908debf53f x86/resctrl: Fix unused variable warning in cache_alloc_hsw_probe()

Only the last of these (1b908debf53f) had been accepted by Boris into TIP x86/cache
when I cut this tree yesterday.

Two more applied by Boris today without any changes from what is in my tree, but the
commit IDs in TIP are obviously different from in my tree.

54e35eb8611c x86/resctrl: Read supported bandwidth sources from CPUID
0976783bb123 x86/resctrl: Remove hard-coded memory bandwidth limit

All the others have the normal risk that Boris will find some way to make them better.
