This patch does the following:
- Remove un-necessary code that is not even compiling into the driver
under TW_OSL_NON_DMA_MEM_ALLOC_PER_REQUEST defines.
- Remove bundled firmware image and associated "files" entry for tw_cl_fwimg.c
- Remove bundled firmware flashing routines. We now have tw_update userspace
FreeBSD controller flash utility.
- Fix driver crash on load due to shared interrupt.
- Fix 2 lock leaks for Giant lock.
- Fix CCB leak.
- Add support for 9650SE controllers.
Many thanks to 3Ware/AMCC for continuing to support FreeBSD.
time workaround for problems with 82571 adapters and LAAs, one port
getting reset can cause the other to have its RAR[0] also reset,
thus overwriting an LAA. This fix works around it by also keeping
the address in the last array member.
The other bug is specific to the new 575 adapter, its transmit code
logic in handling hwassists was too crude, it broken when doing
bridges. I am much happier with the new logic,we may want to change
the legacy path at some point to something similar.

1) adding the thread to the sleepq via sleepq_add() before dropping the
lock, and 2) dropping the sleepq lock around calls to lc_unlock() for
sleepable locks (i.e. locks that use sleepq's in their implementation).
- Split the intr_table_lock into an sx lock used for most things, and a
spin lock to protect intrcnt_index. Originally I had this as a spin lock
so interrupt code could use it to lookup sources. However, we don't
actually do that because it would add a lot of overhead to interrupts,
and if we ever do support removing interrupt sources, we can use other
means to safely do so w/o locking in the interrupt handling code.
- Replace is_enabled (boolean) with is_handlers (a count of handlers) to
determine if a source is enabled or not. This allows us to notice when
a source is no longer in use. When that happens, we now invoke a new
PIC method (pic_disable_intr()) to inform the PIC driver that the
source is no longer in use. The I/O APIC driver frees the APIC IDT
vector when this happens. The MSI driver no longer needs to have a
hack to clear is_enabled during msi_alloc() and msix_alloc() as a result
of this change as well.
- Add an apic_disable_vector() to reset an IDT vector back to Xrsvd to
complement apic_enable_vector() and use it in the I/O APIC and MSI code
when freeing an IDT vector.
- Add a new nexus hook: nexus_add_irq() to ask the nexus driver to add an
IRQ to its irq_rman. The MSI code uses this when it creates new
interrupt sources to let the nexus know about newly valid IRQs.
Previously the msi_alloc() and msix_alloc() passed some extra stuff
back to the nexus methods which then added the IRQs. This approach is
a bit cleaner.
- Change the MSI sx lock to a mutex. If we need to create new sources,
drop the lock, create the required number of sources, then get the lock
and try the allocation again.

VM_PHYSSEG_SPARSE depending on whether the physical address space is
densely or sparsely populated with memory. The effect of this
definition is to determine which of two implementations of
vm_page_array and PHYS_TO_VM_PAGE() is used. The legacy
implementation is obtained by defining VM_PHYSSEG_DENSE, and a new
implementation that trades off time for space is obtained by defining
VM_PHYSSEG_SPARSE. For now, all architectures except for ia64 and
sparc64 define VM_PHYSSEG_DENSE. Defining VM_PHYSSEG_SPARSE on ia64
allows the entirety of my Itanium 2's memory to be used. Previously,
only the first 1 GB could be used. Defining VM_PHYSSEG_SPARSE on
sparc64 allows USIIIi-based systems to boot without crashing.

DIOCGFLUSH - Flush write cache (sends BIO_FLUSH).
DIOCGDELETE - Delete data (mark as unused) (sends BIO_DELETE).
DIOCGIDENT - Get provider's uniqe and fixed identifier (asks for
GEOM::ident attribute).
First two are self-explanatory, but the last one might not be. Here are
properties of provider's ident:
- ident value is preserved between reboots,
- provider can be detached/attached and ident is preserved,
- provider's name can change - ident can't,
- ident value should not be based on on-disk metadata; in other words
copying whole data from one disk to another should not yield the same
ident for the other disk,
- there could be more than one provider with the same ident, but only if
they point at exactly the same physical storage, this is the case for
multipathing for example,
- GEOM classes that consumes single providers and provide single providers,
like geli, gbde, should just attach class name to the ident of the
underlying provider,
- ident is an ASCII string (is printable),
- ident is optional and applications can't relay on its presence.
The main purpose for this is that application and remember provider's ident
and once it tries to open provider by its name again, it may compare idents
to be sure this is the right provider. If it is not (idents don't match),
then it can open provider by its ident.

AC97 Soft Audio and Soft Modem Master Abort Errata
Issue:
Use of either soft audio or soft modem on an Intel® 82443MX PCISet
based platform running a 100 MHz Processor System Bus and an AC97 codec
may result in failures. The system continues to function normally while
the AC97 hardware may not resume and may require a cold-boot to
recover. As a result of the failure, the Master Abort Status bit will
be set in the audio or modem function PCI header space.
Workaround:
Force uncacheable DMA on both BDL and pcm buffers.

- Remove explicit call to pmap_change_attr(), since we now have proper

- Codecs changes:
* Analag Device -> Analog Devices, AD1988.
* New codec: VIA VT1708 and VT1709, Realtek ALC262, ALC861-VD and
ALC885.
* Various fixups for Conexant Waikiki, fix recording (read: microphone)
on various Analog Devices codecs due to vendor BIOS mess, various
quirks for several ASUS laptops/boards.
- Fix connection list handling, closely following the specification to
handle range of nids.

on each socket buffer with the socket buffer's mutex. This sleep lock is
used to serialize I/O on sockets in order to prevent I/O interlacing.
This change replaces the custom sleep lock with an sx(9) lock, which
results in marginally better performance, better handling of contention
during simultaneous socket I/O across multiple threads, and a cleaner
separation between the different layers of locking in socket buffers.
Specifically, the socket buffer mutex is now solely responsible for
serializing simultaneous operation on the socket buffer data structure,
and not for I/O serialization.
While here, fix two historic bugs:
(1) a bug allowing I/O to be occasionally interlaced during long I/O
operations (discovere by Isilon).
(2) a bug in which failed non-blocking acquisition of the socket buffer
I/O serialization lock might be ignored (discovered by sam).
