This was triggered somehow by bca8f17f57bd7 (arm64: Get rid of
asm/opcodes.h) though I didn't figure out how.

Old and broken gas. I have a workaround stashed there:
http://git.kernel.org/cgit/linux/kernel/git/maz/arm-platforms.git/commit/?h=arm64/standalone.h&id=559f97365362ed9e96f594200020379df46630d8
At least binutils 2.24 and 2.25 are affected, while 2.27 is not.
Thanks,
M.

Not that old - this is the Linaro 2015.10 toolchain which wasn't super
new but not exactly from the mists of time either. Anyway, I updated to
2016.11 (GCC 6.2.1, GAS 2.27)... let's see what the fallout is like.

Made me realize that the Ubuntu 15.10 release I'm on is deprecated.
If I read the release notes for Ubuntu correctly the 14.04 LTS release
is supported until April 2019, with binutils 2.24. So I would be
surprised if this won't bite quite a bunch of people down the road.

Catalin has taken a slightly different set of fixes which do address
this problem:
https://git.kernel.org/cgit/linux/kernel/git/arm64/linux.git/commit/?h=for-next/core&id=bbb56c27228d4ad64aca858c5af49d0f2f11c645
https://git.kernel.org/cgit/linux/kernel/git/arm64/linux.git/commit/?h=for-next/core&id=cd9e1927a525f6ce7c0d99c6e038f0a0b9e85176
The build system will warn you that your binutils are broken, and enable
the workaround (which will only result in slightly painful disassembly
for some instructions).
Some of the most visible distros have also other "features", such as
compilers that do not implement basic capabilities on which the kernel
relies for performance (jump labels, for example)...
Thanks,
M.
