Subject[PATCH 0/3] ARC: cache: allow to autodetect L1 cache line size
Date
Allow to autodetect L1 I/D caches line size in runtime instead of
relying on value provided via kconfig.

This patch series is inspired by https://gitsnps.internal.synopsys.com/
arc_oss/linux/commit/c229c6e2e7a62269e2929943ccda2b04149e5b27
however has the following improvements:
* we don't touch any generic code, so it's easier to upstream it.
* autodetection can be disabled via kconfig.
* changes are rebased on latest kernel version.
