e47937d1b7 Add a new driver to support the Intel Non-Transparent Bridge(NTB).
The NTB allows you to connect two systems with this device using a PCI-e
link. The driver is made of two modules:
 - ntb_hw which is a basic hardware abstraction layer for the device.
 - if_ntb which implements the ntb network device and the communication
   protocol.

The driver is limited at the moment to CPU memcpy instead of using DMA, and
only Back-to-Back mode is supported. Also the network device isn't full
featured yet. These changes will be coming soon. The DMA change will also
bring in the ioat driver from the project branch it is on now.

This is an initial port of the GPL/BSD Linux driver contributed by Jon Mason
from Intel. Any bugs are my contributions.

6f2af3fcf3 Rework the handling of the tmpfs node backing swap object and tmpfs
vnode v_object to avoid double-buffering.  Use the same object both as
the backing store for tmpfs node and as the v_object.

Besides reducing memory use up to 2x times for situation of mapping
files from tmpfs, it also makes tmpfs read and write operations copy
twice bytes less.

VM subsystem was already slightly adapted to tolerate OBJT_SWAP object
as v_object. Now the vm_object_deallocate() is modified to not
reinstantiate OBJ_ONEMAPPING flag and help the VFS to correctly handle
VV_TEXT flag on the last dereference of the tmpfs backing object.

e5f299ff76 Make vm_object_page_clean() and vm_mmap_vnode() tolerate the vnode'
v_object of non OBJT_VNODE type.

For vm_object_page_clean(), simply do not assert that object type must
be OBJT_VNODE, and add a comment explaining how the check for
OBJ_MIGHTBEDIRTY prevents the rest of function from operating on such
objects.

For vm_mmap_vnode(), if the object type is not OBJT_VNODE, require it
to be for swap pager (or default), handle the bypass filesystems, and
correctly acquire the object reference in this case.

due to some filesystems, in particular, nfsiods from nfs clients, call
vnode_pager_setsize() with unlocked vnode.

3d31767952 Eliminate the layering violation in the kern_sendfile(). When quering
the file size, use VOP_GETATTR() instead of accessing vnode vm_object
un_pager.vnp.vnp_size.

Take the shared vnode lock earlier to cover the added VOP_GETATTR()
call and, as consequence, the whole internal sendfile loop.  Reduce vm
object lock scope to not protect the local calculations.

Note that this is the last misuse of the vnp_size in the tree, the
others were removed from the ELF image activator by r230246.
