5ca06024ea Add a .note.ABI-tag section to ia64 startup files by linking crtbrand.c
in crt1.o. On other architectures crtbrand.c is included from crt1.c,
but that's not a C source code file on ia64. Instead it is compiled
separately and included in crt1.o using incremental linking.

da2dde653e Fix a long standing (from the original 4.4BSD lite sources) race between
vmspace_fork and vm_map_wire that would lead to "vm_fault_copy_wired: page
missing" panics.  While faulting in pages for a map entry that is being
wired down, mark the containing map as busy.  In vmspace_fork wait until the
map is unbusy, before we try to copy the entries.

c3ffedd66b When reopening a stream backed by an open file descriptor, do not close
the existing file descriptor.  Instead, let dup2() atomically close the
old file descriptor when assigning the newly opened file to the same
descriptor.  This closes a race in a multithreaded application where a
concurrent open() could allocate the existing file descriptor in between
the calls to close() and dup2().

eca7cac32f When r207410 eliminated the acquisition and release of the page queues
lock from pmap_extract_and_hold(), it didn't take into account that
pmap_pte_quick() sometimes requires the page queues lock to be held.
This change reimplements pmap_extract_and_hold() such that it no
longer uses pmap_pte_quick(), and thus never requires the page queues
lock.

For consistency, adopt the same idiom as used by the new
implementation of pmap_extract_and_hold() in pmap_extract() and
pmap_mincore().  It also happens to make these functions shorter.

Fix a style error in pmap_pte().

0c8713f91e Disable attempts to establish a callback connection from the
experimental NFSv4 server to a NFSv4 client when delegations are not
being issued, even if the client advertises a callback path.
This avoids a problem where a Linux client advertises a
callback path that doesn't work, due to a firewall, and then
times out an Open attempt before the FreeBSD server gives up
its callback connection attempt. (Suggested by
drb at karlov.mff.cuni.cz to fix the Linux client problem that
he reported on the fs-stable mailing list.)
The server should probably have
a 1sec timeout on callback connection attempts when there are
no delegations issued to the client, but that patch will require
changes to the krpc and this serves as a work around until then.

1618e3b4d5 r184610 changed the way how TX frames are handled on AX88178 and
AX88772 controllers. ASIX added a new feature for AX88178/AX88772
controllers which allows combining multiple TX frames into a single
big frame. This was to overcome one of USB limitation where it
can't generate more than 8k interrupts/sec which in turn means USB
ethernet controllers can not send more than 8k packets per second.
Using ASIX's feature greatly enhanced TX performance(more than 3~4
times) compared to 7.x driver. However it seems r184610 removed
boundary checking for buffered frames which in turn caused
instability issues under certain conditions. In addition, using
ASIX's feature triggered another issue which made USB controller
hang under certain conditions. Restarting ethernet controller
didn't help under this hang condition and unplugging and replugging
the controller was the only solution. I believe there is a silicon
bug in TX frame combining feature on AX88178/AX88772 controllers.

To address these issues, reintroduce the boundary checking for both
AX88178 and AX88772 after copying a frame to USB buffer and do not
use ASIX's multiple frame combining feature. Instead, use USB
controller's multi-frame transmit capability to enhance TX
performance as suggested by Hans[1].
This should fix a long standing axe(4) instability issues reported
on AX88772 and AX88178 controllers. While I'm here remove
unnecessary TX frame length check since upper stack always
guarantee the size of a frame to be less than MCLBYTES.

Special thanks to Derrick Brashear who tried numerous patches
during last 4 months and waited real fix with patience. Without
this enthusiastic support, patience and H/W donation I couldn't fix
it since I was not able to trigger the issue on my box.
