x86, asmlinkage: Make all interrupt handlers asmlinkage / __visible
These handlers are all referenced from assembler stubs, so need to be visible. The handlers without arguments become asmlinkage, the others __visible to not force regparms(0) on x86-32. I put it all into a single patch, please let me know if you want it it split up.
