The patch crudely forces the NIC out of operating mode before the nve(4)
driver can initialize it; this is required to properly initialize the NIC.
It is XBox-specific, as this condition can only occur on XBoxes (Most loaders
will simply leave the NIC running, forcing us to use a crude workaround like
this to get it in a workable condition). Due to the XBox-only aspect, this has
been solved in XBox-specific initialization code and not within nve(4).

an incompatible conversion from a 64-bit pointer to a 32-bit integer on
64-bit platforms. We will investigate whether Solaris uses a 64-bit
token here, or a new record here, in order to avoid truncating user
pointers that are 64-bit. However, in the mean time, truncation is fine
as these are rarely/never used fields in audit records.

to sbus_mdvec.dv_clock as sbus_mdvec.dv_clock is meant to be specified
in MHz. While this was a bug it shouldn't have affected FreeBSD/sparc64
as sbus_mdvec.dv_clock is used to limit the clock rate of chips when
a machine isn't able to support them at maximum speed which isn't the
case for sun4u machines.
- Remove the code that checks whether the clock frequency returned by
sbus_get_clockfreq() is 0 and falls back to 25MHz if it is as that's
already done in sbus(4).

store some pipe pointers on stack. If user reconfigures dummynet
in the interlock gap, we can work with freed pipes after relock.
To fix this, we decided not to send packets in transmit_event(),
but fill a queue. At the end of dummynet() and dummynet_io(),
after the lock is dropped, if there is something in the queue
we run dummynet_send() to process the queue.

dedicated to storing pv entries, originally so that kva didn't have to be
allocated at inconvenient times. For amd64, we can get the same effect by
using the direct map area. Allocating pages is the same as with the object
backed method, but now we can just lookup the page in the direct map area.
Thus, no more pageable kva is reserved. This is the single largest
consumer of kva on our work machines and this change should help conserve
the fixed size 2GB pageable kva on the amd64 kernel.
There are a pair of sysctl nodes introduced, named the same as their
tunable counterparts. vm.pmap.shpgperproc and vm.pmap.pv_entry_max
They work just like the tunables of the same path, except the values are
linked. The pv entry cap is now dynamically changeable.
I didn't make them totally unlimited because we need some sort of safety
limit still. One could consume all physical memory without a cap.
the system when brelse() was called with B_RELBUF set on the buffer. This
could be a problem when the system was low on memory, had many buffers on
QUEUE_EMPTYKVA and started to traverse directories. For each getnewbuf(),
pages were allocated from the system, driving the free reserve downwards.
For each brelse(), the system put the buffer on QUEUE_CLEAN, with B_INVAL
set.
This commit changes the semantics of B_RELBUF to also free pages from
non-VMIO buffers.
