cff0a327b8 Stop describing an acquire operation as a read barrier and a release
operation as a write barrier.  That description has never been correct,
and it has caused confusion.  An acquire operation orders writes as well
as reads, and a release operation orders reads as well as writes.

Also, explicitly say that a thread doesn't see its own accesses being
reordered.  The reordering of a thread's accesses is only (potentially)
visible to another thread.  Thus, memory barriers need only be used to
control the ordering of accesses between threads, not within a thread.

43ea03d756 Improve the realtime properties of USB transfers for embedded systems
like RPI-B and RPI-2.

Description of problem:
USB transfers can process data in their callbacks sometimes causing
unacceptable latency for other USB transfers. Separate BULK completion
callbacks from CONTROL, INTERRUPT and ISOCHRONOUS callbacks, and give
BULK completion callbacks lesser execution priority than the
others. This way USB audio won't be interfered by heavy USB ethernet
usage for example.

Further serve USB transfer completion in a round robin fashion,
instead of only serving the most CPU hungry. This has been done by
adding a third flag to USB transfer queue structure which keeps track
of looping callbacks. The "command" callback function then decides
what to do when looping.

As a way to make it more difficult to introduce bugs into the ARC, and to
make it easier to diagnose issues when bugs do creep in, it would be
beneficial to change the type of the arc_state_t's arcs_size field to be
a refcount_t instead of a uint64_t. This would allow us to make stricter
checks when incrementing and decrementing the value with debugging enabled,
but still fallback to simple, fast atomic operations when debugging is
disabled.

illumos/illumos-gate@244781f10d

This patch attempts to reduce lock contention on the current arc_state_t
mutexes. These mutexes are used liberally to protect the number of LRU
lists within the ARC (e.g. ARC_mru, ARC_mfu, etc). The granularity at
which these locks are acquired has been shown to greatly affect the
performance of highly concurrent, cached workloads.

6280434f9a Fix text mode operation.
We first map 64KB at 0xA0000 and then determine whether to work
in text or graphics mode.  When graphics mode, the mapping is
precisely what we need and everything is fine.  But text mode,
has the frame buffer relocated to 0xB8000. We didn't map that
much to safely add 0x18000 bytes to the base address.

Now we first check whether to work in text or graphics mode and
then map the frame buffer at the right address and with the
right size (0xA0000+64KB for graphics, 0xB8000+32KB for text).
