[PATCH 02/11] ARM: samsung: fix assembly syntax for new gas

[Arnd Bergmann]

Recent assembler versions complain about extraneous
whitespace inside [] brackets. This fixes all of
these instances for the samsung platforms. We should
backport this to all kernels that might need to
be built with new binutils.

I hope that's also been reported as a bug to the binutils people.

Which binutils version is this?

A.

No, I did not think of that. There were a lot of bug reports for
similar issues and I assumed that there was a good reason for
the change, but I agree that it sounds like a regression, especially
since the code that triggers the error should not be ambiguous and
there was never a warning about it.

I saw it first on the ubuntu binutils-arm-linux-gnueabihf-2.23.1-
0ubuntu6cross1.89 binaries but have now successfully bisected it to
the below commit that introduced the kernel build breakage in the
upstream binutils-2_23-branch.

The changelog comment is rather unhelpful for determining whether
it was intentional or not, and I can't make any sense out of the
source code.
