Subject: byteorder: use generic C version for value byteswapping
From: Harvey Harrison <harvey.harrison@xxxxxxxxx>
This makes the new implementation of the byteorder helpers match the old
in how it degraded when an arch-defined version was not available:
1) swab()
- look for arch defined
- if not, use generic c version
2) swabp()
- look for arch-defined
- if not, deref pointer and use swab()
3) swabs()
- look for arch defined
- if not, use swabp
