SVN rev 191256 on 2009-04-19 00:34:34Z by alc
Allow valid pages to be mapped for read access when they have a non-zero
busy count. Only mappings that allow write access should be prevented by
a non-zero busy count.
(The prohibition on mapping pages for read access when they have a non-
zero busy count originated in revision 1.202 of i386/i386/pmap.c when
this code was a part of the pmap.)
