-+ help
-+ How should we handle alignment errors in userspace by default? This is a bitfield where:
-+ 0 - silently ignore alignment errors (will lead to unexpected results)
-+ 1 - report alignment errors through printk (will lead to unexpected results, but you'll know about them)
-+ 2 - fix the alignment and make things work properly (performance degradation for un-aligned code)
-+ 4 - raise SIGBUS on alignment traps
-+ A good number to choose is probably either 3 (work slowly but log message) or 5 (log message and SIGBUS).
-+ You can change the behavior at runtime through /proc/cpu/alignment if you have PROC_FS enabled.
