Subject: [PATCH 0/3] ARC: cache: allow to autodetect L1 cache line size
Date:   Tue, 16 Apr 2019 20:10:18 +0300

Precedence: bulk

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.
