And the expression "oh bugger" comes to mind.  The breakage in linux-next
is because of 2e57d051160dd61776461637f767df19036b1186 and
ea35455e0dc17d732436a5b98bd511cab64eb10e.

During the last fortnight, I'd moved the "easy to move" ARM headers
from include/asm-arm to arch/arm/include/asm.  This means that, unknown
to me, the symlink was no longer being created.  That didn't get picked
up in my testing, because I always build using O= builds into already
existing object trees, which of course all have the symlink in place.

This doesn't affect kautobuild because that always builds trees without
using the O= facility.

The question is what to do about it.  Given the size of the task, I'm
currently of the opinion that we're moving things around in the wrong
order, and 4baa9922430662431231ac637adedddbb0cfb2d7 should be reverted
until we've moved all the other ARM headers (in asm/arch and asm/plat-*)
first.

Maybe even leaving this until the next merge window now that -rc2 is
out would be a good idea.
