dc6dc1f573 Merge r221614,221696,221737,221840 from largeSMP project branch:
Rewrite atomic operations for powerpc in order to achieve the following:
- Produce a type-clean implementation (in terms of functions arguments
  and returned values) for the primitives.
- Fix errors with _long() atomics where they ended up with the wrong
  arguments to be accepted.
- Follow the sys/type.h specifics that define the numbered types starting
  from standard C types.
- Let _ptr() version to not auto-magically cast arguments, but leave
  the burden on callers, as _ptr() atomic is intended to be used
  relatively rarely.

Fix cfi in order to support the latest point.

cfb00e5aa7 Move the ZERO_REGION_SIZE to a machine-dependent file, as on many
architectures (i386, for example) the virtual memory space may be
constrained enough that 2MB is a large chunk.  Use 64K for arches
other than amd64 and ia64, with special handling for sparc64 due to
differing hardware.

Also commit the comment changes to kmem_init_zero_region() that I
missed due to not saving the file.  (Darn the unfamiliar development
environment).

Arch maintainers, please feel free to adjust ZERO_REGION_SIZE as you
see fit.

9137d17cd9 All architectures define the size-bounded types (uint32_t, uint64_t, etc.)
starting from base C types (int, long, etc).
That is also reflected when building atomic operations, as the
size-bounded types are built from the base C types.

However, powerpc does the inverse thing, leading to a serie of nasty
bugs.
Cleanup the atomic implementation by defining as base the base C type
version and depending on them, appropriately.

2be767e069 Add the watchdogs patting during the (shutdown time) disk syncing and
disk dumping.
With the option SW_WATCHDOG on, these operations are doomed to let
watchdog fire, fi they take too long.

I implemented the stubs this way because I really want wdog_kern_*
KPI to not be dependant by SW_WATCHDOG being on (and really, the option
only enables watchdog activation in hardclock) and also avoid to
call them when not necessary (avoiding not-volountary watchdog
activations).

4309e17add This patch changes head so that the default NFS client is now the new
NFS client (which I guess is no longer experimental). The fstype "newnfs"
is now "nfs" and the regular/old NFS client is now fstype "oldnfs".
Although mounts via fstype "nfs" will usually work without userland
changes, an updated mount_nfs(8) binary is needed for kernels built with
"options NFSCL" but not "options NFSCLIENT". Updated mount_nfs(8) and
mount(8) binaries are needed to do mounts for fstype "oldnfs".
The GENERIC kernel configs have been changed to use options
NFSCL and NFSD (the new client and server) instead of NFSCLIENT and NFSSERVER.
For kernels being used on diskless NFS root systems, "options NFSCL"
must be in the kernel config.
Discussed on freebsd-fs@.

97b53e3634 Switch the GENERIC kernels for all architectures to the new CAM-based ATA
stack. It means that all legacy ATA drivers are disabled and replaced by
respective CAM drivers. If you are using ATA device names in /etc/fstab or
other places, make sure to update them respectively (adX -> adaY,
acdX -> cdY, afdX -> daY, astX -> saY, where 'Y's are the sequential
numbers for each type in order of detection, unless configured otherwise
with tunables, see cam(4)).

ataraid(4) functionality is now supported by the RAID GEOM class.
To use it you can load geom_raid kernel module and use graid(8) tool
for management. Instead of /dev/arX device names, use /dev/raid/rX.

6d2d7b8c0d Fix the interrupt code, broken 7 months ago. The interrupt framework
already supported nested PICs, but was limited to having a nested
AT-PIC only. With G5 support the need for nested OpenPIC controllers
needed to be added. This was done the wrong way and broke the MPC8555
eval system in the process.

OFW, as well as FDT, describe the interrupt routing in terms of a
controller and an interrupt pin on it. This needs to be mapped to a
flat and global resource: the IRQ. The IRQ is the same as the PCI
intline and as such needs to be representable in 8 bits. Secondly,
ISA support pretty much dictates that IRQ 0-15 should be reserved
for ISA interrupts, because of the internal workins of south bridges.
Both were broken.

This change reverts revision 209298 for a big part and re-implements
it simpler. In particular:
o   The id() method of the PIC I/F is removed again. It's not needed.
o   The openpic_attach() function has been changed to take the OFW
    or FDT phandle of the controller as a second argument. All bus
    attachments that previously used openpic_attach() as the attach
    method of the device I/F now implement as bus-specific method
    and pass the phandle_t to the renamed openpic_attach().
o   Change powerpc_register_pic() to take a few more arguments. In
    particular:
    -   Pass the number of IPIs specificly. The number of IRQs carved
	out for a PIC is the sum of the number of int. pins and IPIs.
    -   Pass a flag indicating whether the PIC is an AT-PIC or not.
	This tells the interrupt framework whether to assign IRQ 0-15
	or some other range.
o   Until we implement proper multi-pass bus enumeration, we have to
    handle the case where we need to map from PIC+pin to IRQ *before*
    the PIC gets registered. This is done in a similar way as before,
    but rather than carving out 256 IRQs per PIC, we carve out 128
    IRQs (124 pins + 4 IPIs). This is supposed to handle the G5 case,
    but should really be fixed properly using multiple passes.
o   Have the interrupt framework set root_pic in most cases and not
    put that burden in PIC drivers (for the most part).
o   Remove powerpc_ign_lookup() and replace it with powerpc_get_irq().
    Remove IGN_SHIFT, INTR_INTLINE and INTR_IGN.

Related to the above, fix the Freescale PCI controller driver, broken
by the FDT code. Besides not attaching properly, bus numbers were
assigned improperly and enumeration was broken in general. This
prevented the AT PIC from being discovered and interrupt routing to
work properly. Consequently, the ata(4) controller stopped functioning.

Fix the driver, and FDT PCI support, enough to get the MPC8555CDS
going again. The FDT PCI code needs a whole lot more work.

No breakages are expected, but lackiong G5 hardware, it's possible
that there are unpleasant side-effects. At least MPC85xx support is
back to where it was 7 months ago -- it's amazing how badly support
can be broken in just 7 months...
