Commit Message

Arnd Bergmann Oct. 24, 2016, 3:05 p.m. UTC 
This adds an asm/asm-prototypes.h header for ARM to fix the
broken symbol versioning for symbols exported from assembler
files.

In addition to the header, we have to do these other small
changes:

- move the exports from bitops.h to {change,clear,set,...}bit.S
- move the exports from csumpartialgeneric.S into the files
  including it

I couldn't find the correct prototypes for the compiler builtins,
so I went with the fake 'void f(void)' prototypes that we had
before.

This leaves the mmioset/mmiocpy function for now, as it's not
obvious how to best handle them.
