[GIT PULL] arch/microblaze patches for 7.4-rc1

[Michal Simek]

Hi Linus,

Some issues were found by AI but nothing dramatic.
The signal changes are related to upgrading the toolchains supported by AMD.
Hardened MicroBlaze cores are used in AMD/Xilinx chips, and they will be
supported for another 10+ years. New tests were run as part of this effort, and
that's how the signal stack issues were found.

The KUnit patches have been reviewed by David, and he agreed that they can go
through my tree.

Please pull these patches into your tree.

Thanks,
Michal
