http://perforce.freebsd.org/chv.cgi?CH=159625 Change 159625 by nwhitehorn@nwhitehorn_comporellon on 2009/03/22 20:20:00 Change the UMA zone from which fictitious PVOs are allocated to the unmanaged PVO zone. This is the same as SVN revision 189675 to mmu_oea.c, and likewise prevents a panic when unmaping mmaped physical memory regions.
