60ad8150c7 Retire smp_active. It was racey and caused demonstrated problems with
the cpufreq code.  Replace its use with smp_started.  There's at least
one userland tool that still looks at the kern.smp.active sysctl, so
preserve it but point it to smp_started as well.

7b92a9bfc4 Fix the ATI backlight driver off/on handling. Now this driver works correctly
with the ATI Radeon 9700 in the PowerBook G4 1.67GHz.

Code shamelessly taken in spirit from the radeonkms driver, which I hope will
make this driver redundant in the future.

44f1c91610 Rename global cnt to vm_cnt to avoid shadowing.
To reduce the diff struct pcu.cnt field was not renamed, so
PCPU_OP(cnt.field) is still used. pc_cnt and pcpu are also used in
kvm(3) and vmstat(8). The goal was to not affect externally used KPI.

Bump __FreeBSD_version_ in case some out-of-tree module/code relies on the
the global cnt variable.

Exp-run revealed no ports using it directly.

196321d6b0 Mask out SRR1 bits that aren't exported to the MSR.
This appears to fix a strange condition with X on 32-bit PowerBooks I observed,
caused by one of these bits getting set in the mcontext, but not set in the
thread, which may be a symptom of another problem, more difficult to diagnose.
Since these bits aren't exported anyway, this change makes it more explicit that
the bits aren't MSR-related in SRR1.

65d08437ef Move Open Firmware device root on PowerPC, ARM, and MIPS systems to
a sub-node of nexus (ofwbus) rather than direct attach under nexus. This
fixes FDT on x86 and will make coexistence with ACPI on ARM systems easier.

8279efe54e Switch default Book-E scheduler to ULE, which works now, and enable
CAPABILITIES stuff required to make ssh work.

Hopefully, Book-E can eventually be added to GENERIC, which would avoid
this kind of issue with bitrot. That will require figuring out how to link
Book-E and AIM kernels at the same address, however...

bbc6da03ef Open Firmware interrupt specifiers can consist of arbitrary-length byte
strings and include arbitrary information (IRQ line/domain/sense). When the
ofw_bus_map_intr() API was introduced, it assumed that, as on most systems,
these were either 1 cell, containing an interrupt line, or 2, containing
a line number plus a sense code. It turns out a non-negligible number of
ARM systems use 3 (or even 4!) cells for interrupts, so make this more
general.

169dd953b0 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.

b65c25f54a Fix 32-bit signal handling on ppc64. This was broken when the PSL_USERSTATIC
macro was changed.  Since copying 64-bit srr1 into 32-bit srr1 drops the upper
32 bits, any bits set in the context were dropped, meaning the context check
fails.  Since 32-bit set_context can't change those bits anyway, copy the ones
from the current context (td->td_frame) before calling set_context().

d25b22e12b Fix the resource information for the i2s-a node on certain G5 PowerMacs.
This is the first step needed to get the snapper codec working on those
machines.
The second step is to enable the corresponding I2S device and its clock.

Tested on machines where the snapper codec was already working, a G4 PowerBook
and a PowerMac9,1 with a Shasta based macio.
The PowerMac7,2/7,3 with a K2 based macio can now also play sound.

dcd08302e5 Retire machine/fdt.h as a header used by MI code, as its function is now
obsolete. This involves the following pieces:
- Remove it entirely on PowerPC, where it is not used by MD code either
- Remove all references to machine/fdt.h in non-architecture-specific code
  (aside from uart_cpu_fdt.c, shared by ARM and MIPS, and so is somewhat
  non-arch-specific).
- Fix code relying on header pollution from machine/fdt.h includes
- Legacy fdtbus.c (still used on x86 FDT systems) now passes resource
  requests to its parent (nexus). This allows x86 FDT devices to allocate
  both memory and IO requests and removes the last notionally MI use of
  fdtbus_bs_tag.
- On those architectures that retain a machine/fdt.h, unused bits like
  FDT_MAP_IRQ and FDT_INTR_MAX have been removed.

05e1c598cc Increase PHYS_AVAIL_SZ because on pSeries machines we can have many logical
regions which represent the total amount of memory. The size of these regions
is not the physical size of the chip but it is a logical one and it is given
by the OpenFirmware, it is selectable at boot time and varies between 16MB and
256MB in my case. There is an 'automatic' option which would select the size as
64MB in case you have around 16GB of RAM.
To make sure we can allocate RAM with the automatic option bump this value
of PHYS_AVAIL_SZ to 256.
