[vbox-dev] [PATCH] Fix FreeBSD panic: mutex vm page queue free mutex not owned and PG_UNMANAGED compile problem

[Bernhard Froehlich]

The first hunk of the patch fixes a compile problem on FreeBSD 
10-CURRENT:

Remove explicit initialization of m->flags and m->oflags because per
default vm_phys_alloc_contig() already initializes the page as 
unmanaged.
Chase move of PG_UNMANAGED flag from m->flags to m->oflags and renaming
to VPO_UNMANAGED for an additional assert.


The following hunks fix the following panic on FreeBSD 10-CURRENT 
hosts:

panic: mutex vm page queue free mutex not owned at 
/root/deviant2/sys/vm/vm_phys.c:882
