I came up with the following patch on top of this series that seems to
compile without issue.

That seems to have an implicit dependency of sysreg.h on memory.h, doesn't it?
I had it the other way round initially. I also tried including memory.h in
sysreg.h. That creates a circular dependency mmdebug.h -> bug.h -> ... ->
sysreg.h -> memory.h -> mmdebug.h. Pretty annoying. I could try to fix that,
or create a new header file... :(

I don't think we need this. Any low-level source using MAIR_ELx_SET is bound
to require memory.h as well, one way or another. As this is all #defines,
it won't break anything unless actively used.

And given that this is used in exactly *two* places, I don't believe there
is a need for over-engineering this.

Thanks,
