Excellent, thanks. I'm just about to submit the next version, which relies
on that patch, and no longer checks ALIGNMENT_TRAP for anything.
Other changes:
- Code restructured a bit, from Jamie's comments. It did end up quite a bit
cleaner because of this.
- Comments added for memory barriers, as pointed out by Jamie.
- Added description in Documentation/arm/swp_emulation.
