GCC produces invalid code for microblaze atomics.
The fix is unfortunately not upstream, so fetch it from an external
location and apply it locally.

Queued to testing/next, thanks.
However I didn't see any tests failing so I'm curious where you saw the
problem? Would it be worth adding an atomics test (microblaze or
generic) to catch this?
Also for the Microblaze guys is there any push to upstream the patches
you have into GCC or have an easily distributively binary build we could
convert our dockerfiles to?

I saw you had posted a big gdbstub series. I shall try and get to it once I've finished travelling. -- Alex Bennée Virtualisation Tech Lead @ Linaro
