Hi Geert,
Thanks for sending this out: I think this raises some good questions
about exactly how to handle long running tests (particularly on
older/slower hardware).

changes, even if there's more we can do to better scale to slow

Add cacheinfo support for OpenRISC.
Currently, a few CPU cache attributes pertaining to OpenRISC processors
are exposed along with other unrelated CPU attributes in the procfs file
system (/proc/cpuinfo). However, a few cache attributes remain unexposed.
Provide a mechanism that the generic cache

Hi,
The main purpose of this series is to expose CPU cache attributes for
OpenRISC in sysfs using the cacheinfo API. The core implementation
to achieve this is in patch #3. Patch #1 and #2 add certain enhancements
to simplify the implementation of cacheinfo support.
Patch #1 removes duplication o

other peer can be fast enough to accept the connection and close it
