Remove unnecessary <sys/malloc.h>.

Merge thorpej-cfargs2.

Adapt to CFARGS().

Merge thorpej-cfargs branch:

Simplify and make extensible the config_search() / config_found() /
config_attach() interfaces: rather than having different variants for
which arguments you want pass along, just have a single call that
takes a variadic list of tag-value arguments.

Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
  actually needed.
- Don't be explicit about what interface attribute is attaching if
  the device only has one.  (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
  situations, making is visibly easier to see when indirect config is
  in play, and allowing for future change in semantics.  (As of now,
  this is just a wrapper around config_match(), but that is an
  implementation detail.)

Remove unnecessary or redundant interface attributes where they're not
needed.

There are currently 5 "cfargs" defined:
- CFARG_SUBMATCH (submatch function for direct config)
- CFARG_SEARCH (search function for indirect config)
- CFARG_IATTR (interface attribte)
- CFARG_LOCATORS (locators array)
- CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles)

...and a sentinel value CFARG_EOL.

Add some extra sanity checking to ensure that interface attributes
aren't ambiguous.

Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark
ports to associate those device handles with device_t instance.  This
will trickle trough to more places over time (need back-end for pre-OFW
Sun OBP; any others?).

Convert config_found_ia() call sites where the device only carries
a single interface attribute to bare config_found() calls.

Overhaul the interface to pci_configure_bus():
- Don't expose how PCI bus configuration resource management is implemented.
  Provide a new resource provider API:

  ==> pciconf_resource_init() -- Initialize a PCI configuration resources
      container.
  ==> pciconf_resource_add() -- Add a PCI configuration resource to the
      container (I/O, MEM, or prefetchable MEM).  Multiple resources of
      each type may be added.
  ==> pciconf_resource_fini() -- Tear down the PCI configurtation resources
      container once the bus has been configured.

  This is much easier to use than the previous method of providing an
  extent map for each kind of resource, and works better for e.g. ACPI
  platforms that provide potentially multiple PCI resources in tables
  provided by firmware.

- Re-implement PCI configuration resource management using vmem arenas,
  rather than extent maps.

replace EX_NOWAIT with EX_WAITOK in device attach methods.
remove checks for failures that can no longer occur.

not the SYS_{START,END}.

This fixes mapping of the viaide DMA registers on my Qube2.

PCI_FLAGS_IO_ENABLED and PCI_FLAGS_MEM_ENABLED changed their functional
role in NetBSD (drivers are no longer supposed to write these to
pa_flags) without changing name.  Correct that.

Rename PCI_FLAGS_IO_ENABLED to PCI_FLAGS_IO_OKAY and
PCI_FLAGS_MEM_ENABLED to PCI_FLAGS_MEM_OKAY, thus making their names
consistent with the other PCI flags and poisoning 3rd-party driver
sources that use the flags in the old bad way.

This patch produces no binary changes in this set of PCI kernels when
they are compiled w/o 'options DIAGNOSTIC' and w/ -V MKREPRO=yes:

Adjust things to the new world order.

- Use uvm_lwp_setuarea() instead of directly setting address to lwp_t::l_addr.
- Replace most remaining uses of l_addr with uvm_lwp_getuarea() or lwp_getpcb().
- Amend assembly in ports where it accesses PCB via struct user.
- Rename L_ADDR to L_PCB in few places.  Reduce sys/user.h inclusions.

Phase out the use of a string as first "attach args" member to control
which bustype should be attached with a specific call to config_found()
(from a "mainbus" or a bus bridge).
Do it for isa/eisa/mca and pci/agp for now. These buses all attach to
an mi interface attribute "isabus", "eisabus" etc., and the autoconf
framework now allows to specify an interface attribute on config_found()
and config_search(), which limits the search of matching config data
to these which attach to that specific attribute.
So we basically have to call config_found_ia(..., "foobus", ...) where
such a bus is attached.
As a consequence, where a "mainbus" or alike also attaches other
devices (eg CPUs) which do not attach to a specific attribute yet,
we need at least pass an attribute name (different from "foobus") so
that the foo bus is not found at these places. This made some minor
changes necessary which are not obviously related to the mentioned buses.

- Use bus_space(9) to access PCI configuration registers on GT64111.
- Remove unused pci stuff from mainbus.c.

- Reset timer0 of GT64111 in gt_attach() and start it
  in cpu_initclocks(9) via a callback function.
  Fixes the "hardclock(9) is called before cpu_initclocks(9)" problem
  reported by KIYOHARA Takashi on port-cobalt.
- Use bus_space(9) functions to access GT64111 registers and
  add register definitions for GT64111 in gtreg.h.
  (XXX this could be in sys/dev/marvell?)
- Move microtime(9) from machdep.c to clock.c, and read timer0 register
  via a callback function. Also change microtime(9) like other ports
  to guarantee that the time will be greater than the value obtained
  by a previous call.

__KERNEL_RCSID()

Handle 64bit DMA addresses on PCI for platforms that can (currently only
enabled on amd64). Add a dmat64 field to various PCI attach structures,
and pass it down where needed. Implement a simple new function called
pci_dma64_available(pa) to test if 64bit DMA addresses may be used.
This returns 1 iff _PCI_HAVE_DMA64 is defined in <machine/pci_machdep.h>,
and there is more than 4G of memory.

* Add "pcitag_t *pba_bridgetag" to pci_attach_args.  This is set to
  NULL for root PCI busses.  For busses behind a bridge, it points to
  a persistent copy of the bridge's pcitag_t.  This can be very useful
  for machine-dependent PCI bus enumeration code.
* Implement a machine-dependent pci_enumerate_bus() for sparc64 which
  uses OFW device nodes to enumerate the bus.  When a PCI bus that is
  behind a bridge is attached, pci_attach_hook() allocates a new PCI
  chipset tag for the new bus and sets it's "curnode" to the OFW node
  of the bridge.  This is used as a starting point when enumerating
  that bus.  Root busses get the OFW node of the host bridge (psycho).
* Garbage-collect "ofpci" and "ofppb" from the sparc64 port.

Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.

Sync w/ netbsd-1-5-base.
