Subject: [PATCH 00/14] ARM: randconfig build fixes

From: Arnd Bergmann <arnd@...db.de>

Hi Russell,

This is a set of patches that address various problems building random
configurations. Most of these are older and have been sitting in my
collection of random fixes that I need to get back to. After the -Werror
changes for v5.15, I did that and collected all the patches that fix
something I actually run into. These are the arm32 specific ones that
I think we could merge right away, either for v5.15 as a bugfix or
for v5.16.

Let me know if you have any objections. As the patches are mostly
trivial, I would otherwise send them to your patch tracker once you've
had time to take a look.

There are a few more patches that I'm currently using, but those
are the ones that that are not ready to be merged, either because
they have been rejected before or because they are known to break
something.

      Arnd
