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.

Implement uma_small_alloc() and uma_small_free() for mips that allocates
pages from direct mapped memory. Uses the same mechanism as the page table
page allocator, so that we allocate from KSEG0 in 32 bit, and from XKPHYS
on 64 bit.

It is possible a lower priority thread lending priority to higher priority
thread, in old code, it is ignored, however the lending should always be
recorded, add field td_lend_user_pri to fix the problem, if a thread does
not have borrowed priority, its value is PRI_MAX.

The #define BUILTIN was for building as a csh (not tcsh) builtin.
Given that csh was replaced by tcsh years ago there is no point in keeping
this.
The #define SHELL is for building as an sh builtin and is in active use.
This commit does not change the /bin/sh and /usr/bin/printf binaries.
while on i386 we have MAX_BPAGES=512. Implement this difference via
'#ifdef __i386__'.
With this commit, the i386 and amd64 busdma_machdep.c files become
identical; they will soon be replaced by a single file under sys/x86.
no-op currently, since FreeBSD/amd64 doesn't have (paravirtualized) Xen
support, but if/when that support is ever added we'll want this, and
until then it's harmless.

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.
