kernel - SMP - "Fix AP #%d (PHY# %d) failed" issues
Ok, here's what is going on. If an SMI interrupt occurs while
an AP is going through the INIT/STARTUP IPI sequence the AP will
brick, and nothing you do will resurrect it.
BIOSes typically set up SMI interrupts when emulating (for example)
a PS/2 keyboard with a USB keyboard, or even if just implementing
BIOS support for a USB keyboard. Even worse, the BIOS may set up
the interrupt to poll at 1000hz. And, EVEN WORSE, it can totally
depend on which USB port you've plugged your keyboard in. And, on top
of all of that, the SMI interrupt is not consistent.
The INIT/STARTUP code contains a 10ms delay (as per Intel spec) between
the INIT IPI and the STARTUP IPI. Well, you can do the math.
In order to reliably boot a SMP system where the BIOS has set up
SMI interrupts this patch uses a nifty bit of code to detect when
the SMI interrupt has occurred and tries to shift the INIT/STARTUP
sequence into a gap between SMI interrupts. If it has to it will
reduce the 10ms spec delay all the way down to 150us. In many
cases we really have no choice for reliable operation. Even a 300uS
delay is too much in the tests I performed on a Shuttle Phenom and
Phenom II cube. I don't honestly know if this will break other SMP
configurations, we'll have to see.
On the particular shuttle I tested on, one of the four USB connections
on the backpanel (the upper left when looking at it from the back)
seemed to cause the BIOS to set up SMI interrupts at a high rate and
caused kernel boots to fail. With this commit those boots now succeed.

* Detect the case where B-Tree leafs are being laid down sequentially,

It should be noted that the HAMMER flush sorts by inode so directory

kernel - Improve cluster_read()
* The cluster_read() code was tripping over itself due to a findblk()
call which caused it to believe it had found a buffer hole when it
really found a busy buffer.
Redo the code to use the FINDBLK_TEST flag to locate the next buffer
hole. Also add a shortcut to support efficient coding for larger
read-ahead values.
* Change the single-read-ahead in cluster_read() to a multiple-read-ahead
based on the maxra parameter. Before we just did a single read-ahead
and even though this was a cluster read it still created a situation
where the next cluster_read(0 operation would stall on previous read-ahead
before issuing the next one. In otherwords, it wasn't pipelining requests
as well asit could.
This change tries to keep at least two read-aheads in progress so when
the next cluster_read() stalls on the first one the second one is still
in the pipeline after it unstalls, allowing it to issue the third one
to keep the pipeline hot.
* These changes improve SSD swapcache operation as well as normal HD
cluster_read() pipelining. In addition the read-ahead is now sufficient
to keep the pipeline hot across a 2 x Swap (interleaved) setup.

kernel - SWAP CACHE part 14/many - Add more features, man page
* Implement write clustering. Swapcache attempts to cluster writes
for optimal matching between swap and the buffer cache. This
also reduces the IOPS for writes by a factor 16. The SSD should
be able to do write combining and erasing more optimally as well.
* Add vm.swapcache.minburst
This ensures that curburst is allowed to recover sufficiently that
a nice good write burst can be done, once curburst hits 0. Otherwise
swapcache winds up doing tiny bursts which tend to fragment the cache.
* Add vm.swapcache.maxfilesize
If set to non-zero prevents swapcache from caching files larger than
the specified size. That is, swapcache will only cache smaller files.
This is experimental because there are issues caching small files
anyway (the vnodes get recycled too quickly).
* Allow vm.swapcache.curburst to be manually set larger than
vm.swapcache.maxburst, so the initial load-in can be different
from the maximum reburst.
* Adjust the code which deals with write errors on swap to ensure
that the backing store is destroyed (because it isn't a clean copy).
