c8d2ffd6a7 Merge all MD sf_buf allocators into one MI, residing in kern/subr_sfbuf.c
The MD allocators were very common, however there were some minor
differencies. These differencies were all consolidated in the MI allocator,
under ifdefs. The defines from machine/vmparam.h turn on features required
for a particular machine. For details look in the comment in sys/sf_buf.h.

As result no MD code left in sys/*/*/vm_machdep.c. Some arches still have
machine/sf_buf.h, which is usually quite small.

49588d0fac Move the PS3 framebuffer console to use vt instead of syscons and adjust
GENERIC64 for PowerPC to use vt with it.

Much to my chagrin, PS3 support seems to have bitrotted somewhat since the
last time I tried it. ehci panics on attach and interrupt handling seems
to be faulty. This should be fixed soon...

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

debe445512 Split the function of the PCB_FPU flags into two: PCB_FPU now indicates that
the actual FPU is enabled, while PCB_FPREGS indicates that the FPU state
structure in the PCB is valid. This separation reflects the situation on
FPU-less systems in which the FP state is used by the emulator but we don't
actually want to try to turn on the non-existant FPU.

Use this flag to save and restore FP regs properly on both AIM and Book-E.
As a side effect, this sets up hard-FP and Altivec on Book-E CPUs with such
abilities except for a trap handler to call enable_fpu()/enable_altivec().

817ba5c0b8 Following the approach with ACPI DMAR on x86, split IOMMU handling into
a variant PCI bus instead of trying to shoehorn it into the PCI host bridge
adapter. Besides matching better the architecture on other platforms, this
also allows systems with multiple partitionable endpoints per PCI host

bdac436008 Follow up r223485, which made AIM use the ABI thread pointer instead of
PCPU fields for curthread, by doing the same to Book-E. This closes
some potential races switching between CPUs. As a side effect, it turns out
the AIM and Book-E swtch.S implementations were the same to within a few
registers, so move that to powerpc/powerpc.

302acc2e5f Rename the "bare" platform "mpc85xx", which is what it actually is, and
add actual platform probing based on PVR. Still needs a little more work:
in particular, the CCRS setup should move here.

Also turn "bare" into a truly bare platform that doesn't pretend to know how
to do anything except get the memory map. This should also be enhanced to
process the FDT reserved memory list, but that is for another day.

exception of POWER3-based systems when run in 64-bit mode. The main
development target, however, has been the PAPR logical partition support
that is the default target in KVM on POWER and QEMU -- mileage may vary

cb34ed4434 Add basic support for FDT to i386 & amd64. This change includes:
1.  Common headers for fdt.h and ofw_machdep.h under x86/include
    with indirections under i386/include and amd64/include.
2.  New modinfo for loader provided FDT blob.
3.  Common x86_init_fdt() called from hammer_time() on amd64 and
    init386() on i386.
4.  Split-off FDT specific low-level console functions from FDT
    bus methods for the uart(4) driver. The low-level console
    logic has been moved to uart_cpu_fdt.c and is used for arm,
    mips & powerpc only. The FDT bus methods are shared across
    all architectures.
5.  Add dev/fdt/fdt_x86.c to hold the fdt_fixup_table[] and the
    fdt_pic_table[] arrays. Both are empty right now.

FDT addresses are I/O ports on x86. Since the core FDT code does
not handle different address spaces, adding support for both I/O
ports and memory addresses requires some thought and discussion.
It may be better to use a compile-time option that controls this.

In the while SMBFS regular users can use FUSE interface and smbnetfs
port to work with their SMBFS partitions.

Also, there are ongoing efforts by vendor to support in-kernel smbfs,
so there are good chances that it will get relinked once properly locked.

31ec0f7a83 Initial support for running FreeBSD on the Nintendo Wii. We're able to
reach single user mode using a memory disk device as the file system.

This port includes the framebuffer driver, the PIC driver, a platform
driver and the GPIO driver. The IPC driver (to talk to IOS kernels) is
not yet written but there's a placeholder for it.

There are still some MMU problems and to get a working system you need to
patch locore32.S. Since we haven't found the best way yet to address that
problem, we're not committing those changes yet. The problem is related to
the different BAT layout on the Wii and to the fact that the Homebrew
loader doesn't clean up the special registers (including the 8 BATs)
before passing control to us.

You'll need a Wii with Homebrew loader and a TV that can do NTSC (for now).

aea810386d Implement mechanism to export some kernel timekeeping data to
usermode, using shared page.  The structures and functions have vdso
prefix, to indicate the intended location of the code in some future.

The versioned per-algorithm data is exported in the format of struct
vdso_timehands, which mostly repeats the content of in-kernel struct
timehands. Usermode reading of the structure can be lockless.
Compatibility export for 32bit processes on 64bit host is also
provided. Kernel also provides usermode with indication about
currently used timecounter, so that libc can fall back to syscall if
configured timecounter is unknown to usermode code.

The shared data updates are initiated both from the tc_windup(), where
a fast task is queued to do the update, and from sysctl handlers which
change timecounter. A manual override switch
kern.timecounter.fast_gettime allows to turn off the mechanism.

Only x86 architectures export the real algorithm data, and there, only
for tsc timecounter. HPET counters page could be exported as well, but
I prefer to not further glue the kernel and libc ABI there until
proper vdso-based solution is developed.

Minimal stubs neccessary for non-x86 architectures to still compile
are provided.
