Yes, right. In the mean time, I discovered the discussion you had with
Hauke on the v2 of his patch series, and started looking at your
for-next branch. I wanted to give a test before reporting back, and
it's now done: with "ARM: l2c: write auxiliary control register first"
+ Hauke's patch, it works fine for me.
Thanks!
