Add hwpmc(4) support for the PowerPC 970 class processors, direct events.
This also fixes asserts on removal of the module for the mpc74xx.

The PowerPC 970 processors have two different types of events: direct events
and indirect events. Thus far only direct events are supported. I included
some documentation in the driver on how indirect events work, but support is
for the future.

Let us manage differences of Book-E PowerPC variations i.e. vendor /
implementation specific vs. the common architecture definition.

Bring PPC4XX defines (PSL, SPR, TLB). Note the new definitions under
BOOKE_PPC4XX are not used in the code yet.

This change set is not supposed to affect existing E500 support, it's just
another reorg step before bringing support for E500mc, E5500 and PPC465.

Provide SPR definitions for newer Book-E (E500mc, E5500, PPC465).

Obtained from: Freescale, Semihalf.

Unify SPR defines formatting, no funtional changes.

Implement hwpmc counting PMC support for PowerPC G4+ (MPC745x/MPC744x).
Sampling is in progress.

o Add system versions for the P4040(E) and P4080(E).
o In bare_probe(), change the logic that determines the maximum
number of processors/cores into a switch statement and take
advantage of the fact that bit 3 of the SVR value indicates
whether we're running on a security enabled version. Since we
don't care about that here, mask the bit. All -E versions
are taken care of automatically.

o Swap the SVR numbers for MPC8533 & MPC8533E
o Add SVR defines for P1011(E), P1020(E), P2010(E) & P2020(E)

Fix handling of NX pages on capable CPUs. Thanks to kib for prodding me

Add CPU support code for the IBM Cell Broadband Engine.

Kernel sources for 64-bit PowerPC, along with build-system changes to keep
32-bit kernels compiling (build system changes for 64-bit kernels are
coming later). Existing 32-bit PowerPC kernel configurations must be
updated after this change to specify their architecture.

The NetBSD Foundation has granted permission to remove clause 3 and 4 from
their software.

Add SMP support on U3-based G5 systems. This does not yet work perfectly:
at least on my Xserve, getting the decrementer and timebase on APs to tick
requires setting up a clock chip over I2C, which is not yet done.

While here, correct the 64-bit tlbie function to set the CPU to 64-bit
mode correctly.

Fix copy/paste typo in last revision. PMC0 control should be shifted 8
bits, not 6, on the PPC 970.

Teach cpu_est_clockrate() about the G5's slightly different PMC. This
allows the boot messages to include the CPU speed and makes possible
the forthcoming cpufreq support for the PPC 970.

Initial support for SMP on PowerPC MPC85xx.

PowerPC common SMP startup and time base rework.

- make mftb() shared, rewrite in C, provide complementary mttb()
- adjust SMP startup per the above, additional comments, minor naming
changes
- eliminate redundant TB defines, other minor cosmetics

Factor out platform dependent things unrelated to device drivers into a
new platform module. These are probed in early boot, and have the
responsibility of determining the layout of physical memory, determining
the CPU timebase frequency, and handling the zoo of SMP mechanisms
found on PowerPC.

Rework the way we get the cacheline size. Instead of having a table of
CPUs known to use 128 byte cache lines and defaulting to 32, use the dcbz
instruction to measure it. Also make dcbz behave the way you would
expect on PPC 970.

Add support for 64-bit PowerPC CPUs operating in the 64-bit bridge mode
provided, for example, on the PowerPC 970 (G5), as well as on related CPUs
like the POWER3 and POWER4.

This also adds support for various built-in hardware found on Apple G5
hardware (e.g. the IBM CPC925 northbridge).

NOTE: This undoes some changes I'd made to prefix the processor name defines
with PVR_. This was due to my original decision to use MPC750 as a cpu name.
With this changed, the PVR_ change is no longer required.

Rename the constants for the contents of the PVR register so as not to
conflict with cpu names used in config files..

Commit of stuff that's been sitting in my tree for a while.

Highlights include:
- New low-level trap code from NetBSD. The high level code still needs a lot
of work.
- Fixes for some pmap handling in thread switching.
- The kernel will now get to attempting to jump into init in user mode. There
are some pmap/trap issues which prevent it from actually getting there though.
