5ba0615c03 Optimize intr_execute_handlers() by combining the pic_disable_source() and
pic_eoi_source() into one call.  This halves the number of spinlock operations
and indirect function calls in the normal case of handling a normal (ithread)
interrupt.  Optimize the atpic and ioapic drivers to use inlines where
appropriate in supporting the intr_execute_handlers() change.

This knocks 900ns, or roughly 1350 cycles, off of the time spent servicing an
interrupt in the common case on my 1.5GHz P4 uniprocessor system.  SMP systems
likely won't see as much of a gain due to the ioapic being more efficient than
the atpic.  I'll investigate porting this to amd64 soon.

67dab3d6c9 When searching for a suitable block of memory on the free list,
skip blocks that are too big by a factor of two or greater. This
avoids some cases of extremely inefficient memory use that can occur
when large (e.g. 64k) blocks on the free list get used when allocating
a 4k chunk of 64-byte fragments. Because fragments have their own
free list, the 60k difference got lost forever every time.

da37d6ad41 Attempt to follow the correct procedure for synchronising with the
system BIOS to disable legacy device emulation as per the "EHCI
Extended Capability: Pre-OS to OS Handoff Synchronisation" section
of the EHCI spec. BIOSes that implement legacy emulation using SMIs
are supposed to disable the emulation when this procedure is performed.

969ff54d70 - Fix unloading by the same way it is done in my other classes:
set gp->softc to NULL and return ENXIO when it is NULL, so GEOM
  will not panic or hang, but unload one device on every 'unload'.
  This make 'unload' command usable, but it have to be executed
  <number of devices> + 1 times.
- Made use of 'pp' variable.

b23f72e98a * Add a "how" argument to uma_zone constructors and initialization functions
so that they know whether the allocation is supposed to be able to sleep
  or not.
* Allow uma_zone constructors and initialation functions to return either
  success or error.  Almost all of the ones in the tree currently return
  success unconditionally, but mbuf is a notable exception: the packet
  zone constructor wants to be able to fail if it cannot suballocate an
  mbuf cluster, and the mbuf allocators want to be able to fail in general
  in a MAC kernel if the MAC mbuf initializer fails.  This fixes the
  panics people are seeing when they run out of memory for mbuf clusters.
* Allow debug.nosleepwithlocks on WITNESS to be disabled, without changing
  the default.

Both bmilekic and jeff have reviewed the changes made to make failable
zone allocations work.

8ea534a9c0 The watchdog callout executes with the (non-sleepable) ifnet lock held
now, but it's possible for ndis_reset_nic() to sleep (sometimes the
MiniportReset() method returns NDIS_STATUS_PENDING and we have
to wait for completion). To get around this, execute the ndis_reset_nic()
routine in the NDIS_TASKQUEUE thread.

f13b900a9e Big mess 'o changes:
- Give ndiscvt(8) the ability to process a .SYS file directly into
  a .o file so that we don't have to emit big messy char arrays into
  the ndis_driver_data.h file. This behavior is currently optional, but
  may become the default some day.

- Give ndiscvt(8) the ability to turn arbitrary files into .ko files
  so that they can be pre-loaded or kldloaded. (Both this and the
  previous change involve using objcopy(1)).

- Give NdisOpenFile() the ability to 'read' files out of kernel memory
  that have been kldloaded or pre-loaded, and disallow the use of
  the normal vn_open() file opening method during bootstrap (when no
  filesystems have been mounted yet). Some people have reported that
  kldloading if_ndis.ko works fine when the system is running multiuser
  but causes a panic when the modile is pre-loaded by /boot/loader. This
  happens with drivers that need to use NdisOpenFile() to access
  external files (i.e. firmware images). NdisOpenFile() won't work
  during kernel bootstrapping because no filesystems have been mounted.
  To get around this, you can now do the following:

        o Say you have a firmware file called firmware.img
        o Do: ndiscvt -f firmware.img -- this creates firmware.img.ko
        o Put the firmware.img.ko in /boot/kernel
        o add firmware.img_load="YES" in /boot/loader.conf
        o add if_ndis_load="YES" and ndis_load="YES" as well

  Now the loader will suck the additional file into memory as a .ko. The
  phony .ko has two symbols in it: filename_start and filename_end, which
  are generated by objcopy(1). ndis_open_file() will traverse each module
  in the module list looking for these symbols and, if it finds them, it'll
  use them to generate the file mapping address and length values that
  the caller of NdisOpenFile() wants.

  As a bonus, this will even work if the file has been statically linked
  into the kernel itself, since the "kernel" module is searched too.
  (ndiscvt(8) will generate both filename.o and filename.ko for you).

- Modify the mechanism used to provide make-pretend FASTCALL support.
  Rather than using inline assembly to yank the first two arguments
  out of %ecx and %edx, we now use the __regparm__(3) attribute (and
  the __stdcall__ attribute) and use some macro magic to re-order
  the arguments and provide dummy arguments as needed so that the
  arguments passed in registers end up in the right place. Change
  taken from DragonflyBSD version of the NDISulator.

2dacb7cc04 Implement basic support for EHCI interrupt pipes. This is unlikely
to be particularly correct or optimal, but it seems to be enough
to allow the attachment of USB2 hubs and USB2 devices connected via
USB2 hubs. None of the split transaction support is implemented in
our USB stack, so USB1 peripherals will definitely not work when
connected via USB2 hubs.

8ab2f5ecc5 Break out the MI part of the /dev/[k]mem and /dev/io drivers into
their own directory and module, leaving the MD parts in the MD
area (the MD parts _are_ part of the modules). /dev/mem and /dev/io
are now loadable modules, thus taking us one step further towards
a kernel created entirely out of modules. Of course, there is nothing
preventing the kernel from having these statically compiled.

4b2e596e38 Handle spoil event in dedicated function: g_mirror_spoiled().
The different between the new function and g_mirror_orphan() (which was
used previously) is that syncid is bumped immediately, instead of on
first write, because when consumer was spoiled, it means, that its
provider was opened for writing, so we can't trust that its data
will be valid when it will be connected again.
