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.

The difference between this patch series and the previous version [1] is
minor. The email address used in 'From' and 'signed-off-by' are now the
same so checkpatch does not throw a FROM_SIGN_OFF_MISMATCH warning.

The patch also addresses a build warning that was caught by the kernel
test robot [2] and addressed in a standalone patch earlier [3].

Thanks,
Sahil
