Hi Arnd,

commit 8ab2ae655bf ("default exported asm symbols to zero") results
in the following build error when building alpha:allmodconfig.

arch/alpha/lib/callback_srm.S: Assembler messages:

I tried with the 4.6.3 toolchain from kernel.org (binutils 2.22)
and with a self-built toolchain based on gcc 5.1.0 and binutils 2.24.
