[3/3] ARM: fix asm symbol exports

Commit Message

Nicolas Pitre Nov. 30, 2016, 8:50 a.m. UTC

This assumes a revert of commit 8478132a87 before being applied.

Annotate exported assembly symbols so they are properly checksummed
when modversion is selected.

Also, don't use \name with EXPORT_SYMBOL() in bitops.h. Here \name is
an assembler macro argument which is not subject to preprocessor
substitutions. And the assembler doesn't handle preprocessor macros
either. That has the effect of breaking CONFIG_TRIM_UNUSED_KSYMS=y.
