Today's -next fails to build an ARM allmodconfig due to:

which appears to be caused by 535e20f083e6 ({net,IB}/mlx5: QP/XRCD
commands via mlx5 ifc).  outb() just isn't available as standard on ARM,
it's not something that's meaningful for the hardware.

Thanks Mark for catching it.

It puzzles me how it passed all other compilations (internals and
externals) without failures. On my machine (x86-64), old and new
versions compile without errors.

This failure isn't related to OUT assembly instruction, but to typo in
pointer name declaration. It was declared as "u32 *out", but "outb" was
used.
