Sub-Numa Clustering (SNC) allows splitting CPU cores, caches and memory

SNC support was merged into the kernel [1]. With SNC enabled
and kernel support in place all the tests will function normally (aside
from effective cache size). There might be a problem when SNC is enabled
but the system is still using an older kernel version without SNC
support. Currently the only message displayed in that situation is a
guess that SNC might be enabled and is causing issues. That message also
is displayed whenever the test fails on an Intel platform.
Add a mechanism to discover kernel support for SNC which will add more
meaning and certainty to the error message.
Add runtime SNC mode detection and verify how reliable that information
is.
Series was tested on Ice Lake server platforms with SNC disabled, SNC-2
and SNC-4. The tests were also ran with and without kernel support for
SNC.
Series applies cleanly on kselftest/next.
Could you please consider this series for inclusion?
Thank you very much.

This series still applies cleanly to kselftest/next. Could you please
consider it for inclusion?
Thank you very much.

Thank you for bumping it up to top of my Inbox.
I will apply these for 6.14-rc1 now.
thanks,
