Hi Dan,
In async_mult(...) of async_raid6_recov.c, the count 3 is used to request an

However the to_cnt and bidi_cnt are both set to 1 and from_cnt to 0.
Then while trying to do unmap, we are getting the wrong unmap from a

We have a function where the arch can be queried, syscall_get_arch().
So rather than have every single piece of arch specific code use and/or
duplicate syscall_get_arch(), just have the audit code use the
syscall_get_arch() code.
