commit fb95090730360b6b7f5429c40937e8fc9dfe5c14
Author: Matt Turner <mattst88 at gmail.com>
Date: Mon Nov 9 03:33:45 2009 +0000
Use glibc's in/out routines
Let's let glibc do the right thing for dense/sparse selection.
The _alpha_iobase code has been unused since the switch to libpciaccess. It
really should have been killed by fba700f1f6a8976.
