New Revision: 264179
URL: http://svnweb.freebsd.org/changeset/base/264179
Log:
Make the vmm code compile with gcc too. Not entirely sure things are
correct for the pirbase test (since I'd have thought we'd need to do
something even when the offset is 0 and that test looks like a
misguided attempt to not use an uninitialized variable), but it is at
least the same as today.
