Initial import of binutils 2.22 on the new vendor branch

Future versions of binutils will also reside on this branch rather
than continuing to create new binutils branches for each new version.

resource: Per-CPU hardware resources support, step 4 of many

Add cpuid parameter to bus_alloc_resource DEVMETHOD, so cpuid
could be passed all the way to the nexus

it for quite a long time :P

Do a major clean-up of the BUSDMA architecture. A large number of
essentially machine-independant drivers use the structures and definitions
in machine-dependant directories that are really machine-independant in
nature.

Split <machine/bus_dma.h> into machine-depdendant and machine-independant parts
and make the primary access run through <sys/bus_dma.h>.

Remove <machine/bus.h>, <machine/bus_memio.h> and <machine/bus_pio.h>. The
optimizations related to bus_memio.h and bus_pio.h made a huge mess,
introduced machine-specific knowledge into essentially machine-independant
drivers, and required specific #include file orderings to do their job.
They may be reintroduced in some other form later on.

Move <machine/resource.h> to <sys/bus_resource.h>. The contents of the file
is machine-independant or can be made a superset across many platforms.

Make <sys/bus.h> include <sys/bus_dma.h> and <sys/bus_resource.h> and
include <sys/bus.h> where necessary. Remove all #include's of
<machine/resource.h> and <machine/bus.h>. That is, make the BUSDMA
infrastructure integral to I/O-mapped and memory-mapped accesses to devices
and remove a large chunk of machine-specific dependancies from drivers.
bus_if.h and device_if.h are now required to be present when using <sys/bus.h>.

Remove the now unused interlock argument to the lockmgr() procedure.
This argument has been abused over the years by kernel programmers
attempting to optimize certain locking and data modification sequences,
resulting in a virtually unreadable code in some cases. The interlock
also made porting between BSDs difficult as each BSD implemented their
interlock differently. DragonFly has slowly removed use of the interlock
argument and we can now finally be rid of it entirely.

Get rid of bus_{disable,enable}_intr(), it wasn't generic enough for
our needs.

Implement some generic atomic.h functions to aid in the implementation of
a low level mutex.

Implement a generic low level sleep-mutex serializer, kern/lwkt_serialize.c.
The serializer is designed to be a replacement for SPL calls but may also
be used for other very low level work (e.g. lockmgr interlocks).

Add a serializer argument to BUS_SETUP_INTR(). When non-NULL, the interrupt
handler will no longer be protected by an SPL so e.g. spl*() will no
longer protect against that device's interrupts.

The IF queueing and dequeueing mechanisms may no longer depend on outside
SPL state because network driver interrupt handlers are no longer required to
enter splnet(). Use critical sections for the moment. The IFQ and
IFF_OACTIVE interactions are not yet MP safe.

A kludge to always give the driver a second chance to attach the cbb device.

Similar to the following part of FreeBSD rev 1.66 by imp:
o Remove bogus checks when reallocating memory for the registers. They
weren't needed and turned out to be completely bogus.

This lets me load/unload pccard with a pccard in a slot and have the
child correctly detach/attach. This should help people that have wi
in their kernel, but that kldload cbb and pccard, for example.

Temporary switch the cardbus interrupt from INTR_TYPE_AV to

Fix some issues with the pccard shutdown path (during reboot and halt).
pccard was resetting the bridge controller and unmapping the device
without first detaching/shutting down the helper thread or disabling the
interrupt, and without calling the shutdown function for the children,
leading to several actual and potential lockups during a halt/reboot
sequence.

There was also a bug in the thread termination code that could deadlock
the system... the thread interlock was being improperly held while
looping waiting for thread termination. Finally, there was an instance
where sc->flags was being manipulated without holding the proper lock.

Rearrange the dev/pccard/pccbb shutdown code to (A) call the shutdown
vector for the children, (B) disable the associated interrupt, and
(C) properly terminate the helper thread, and fix the other bugs that
were found.

There are still known issues not addressed by this patch, including
interrupt storms from the cardbus system during halt/reboot (currently
mostly caught by our interrupt rate limiting code), and at least one
unknown deadlock can still occur during halt/reboot.

Newtoken commit. Change the token implementation as follows: (1) Obtaining
a token no longer enters a critical section. (2) tokens can be held through
schedular switches and blocking conditions and are effectively released and
reacquired on resume. Thus tokens serialize access only while the thread
is actually running. Serialization is not broken by preemptive interrupts.
That is, interrupt threads which preempt do no release the preempted thread's
tokens. (3) Unlike spl's, tokens will interlock w/ interrupt threads on
the same or on a different cpu.

The vnode interlock code has been rewritten and the API has changed. The
mountlist vnode scanning code has been consolidated and all known races have
been fixed. The vnode interlock is now a pool token.

The code that frees unreferenced vnodes whos last VM page has been freed has
been moved out of the low level vm_page_free() code and moved to the
periodic filesystem sycer code in vfs_msycn().

The SMP startup code and the IPI code has been cleaned up considerably.
Certain early token interactions on AP cpus have been moved to the BSP.

The LWKT rwlock API has been cleaned up and turned on.
