- In OF_init() if obtaining the memory or mmu handle fails just call
OF_exit() instead of panic() as the loader hasn't initialized the
console at these early stages yet and trying to print out something

OF_call_method() the formers should never have been in the MI part
of the loader as contrary to the OFW spec they use two-cell physical

These CPUs use an enhanced layout of the interrupt vector dispatch
and dispatch status registers in order to allow sending IPIs to
multiple targets simultaneously. Thus support for these CPUs was
put in a newly added cheetah_ipi_selected(). This is intended to
be pointed to by cpu_ipi_selected, which now is a function pointer,
in order to avoid cpu_impl checks once booted. Alternatively it
can point to spitfire_ipi_selected(), which was renamed from
cpu_ipi_selected(). Consequently cpu_ipi_send() was also renamed
to spitfire_ipi_send() (there's no need for a cheetah equivalent
of this so far). Initialization of the cpu_ipi_selected pointer
and other requirements is done in mp_init(), which was renamed
from mp_tramp_alloc(), as cpu_mp_start() isn't called on UP
systems while cpu_ipi_selected() is. As a side-effect this allows
to make mp_tramp static to sys/sparc64/sparc64/mp_machdep.c.
For the sake of avoiding #ifdef SMP and for keeping the history in
place cheetah_ipi_selected() and spitfire_ipi_{selected,send}()

- Add some CTASSERTs and KASSERTs ensuring that MAXCPU doesn't
exceed the data types we use to store the CPU bit fields or the
number of USIII and greater CPUs supported by the current
cheetah_ipi_selected() implementation (which for JBus-CPUs is
only 4; that should be fine though as according to OpenSolaris
there are no sun4u machines with more than 4 JBus-CPUs).
- In cpu_mp_start() don't enumerate and start more than MAXCPU CPUs
as we can't handle more than that.
- In cpu_mp_start() check for upa-portid vs. portid depending on
cpu_impl for consistency with nexus(4).
- In spitfire_ipi_selected() add KASSERTs ensuring that a CPU isn't
told to IPI itself as sun4u CPUs just can't do that.
- In spitfire_ipi_send() do a MEMBAR #Sync after writing the
interrupt vector data as we want to make sure the payload was
actually written before we trigger the dispatch.
- In spitfire_ipi_send() also verify IDR_BUSY when checking whether
the dispatch was successful as it has to be cleared for this to
be the case.
- Remove some redundant variables.

"static". The header file generated by "rpcgen -h" will always declare
it as extern, leading to a "static after extern" error being issued by
gcc-4.2. This caused only a warning in gcc-3.x, but it has been wrong
all the time.
This change does not modify the code generated by "rpcgen -m", it only
affects rpcgen used to generate server stubs with a local main function.
This is the minimal patch. It does not remove the now obsolete "storage"
parameter from write_program() and write_programs() in an attempt to keep
differences to other systems' versions of rpcgen as small as possible.

This allocator uses a binary buddy system with a twist. First and
foremost, this allocator is required to support the implementation of
superpages. As a side effect, it enables a more robust implementation
of contigmalloc(9). Moreover, this reimplementation of
contigmalloc(9) eliminates the acquisition of Giant by
contigmalloc(..., M_NOWAIT, ...).
The twist is that this allocator tries to reduce the number of TLB
misses incurred by accesses through a direct map to small, UMA-managed
objects and page table pages. Roughly speaking, the physical pages
that are allocated for such purposes are clustered together in the
physical address space. The performance benefits vary. In the most
extreme case, a uniprocessor kernel running on an Opteron, I measured
an 18% reduction in system time during a buildworld.
This allocator does not implement page coloring. The reason is that
superpages have much the same effect. The contiguous physical memory
allocation necessary for a superpage is inherently colored.
Finally, the one caveat is that this allocator does not effectively
support prezeroed pages. I hope this is temporary. On i386, this is
a slight pessimization. However, on amd64, the beneficial effects of
the direct-map optimization outweigh the ill effects. I speculate
that this is true in general of machines with a direct map.

- General sleep call through msleep(9) has been converted to condvar(9)

- Heavily guard every possible "slow path" entries (open(), close(),
few ioctl()s, sysctls), but once it entering "fast path" (io, interrupt
started), they are free to fly on their own.
- Rearrange locking sequences, resulting better concurrency and
serialization. Large part doesn't even need locking at all, and will be
removed in future. Less clutter, except in few places due to lock
ordering.

- Add few mix_[get|set|..] functions to avoid calling mixer_ioctl()
directly using cryptic arguments.
- Locking fixes to avoid possible deadlock with (still under Giant) USB.
- Better simplex/duplex device handling.
- Recover mmap() functionality for recording, which has been lost
since 2.2.x - 3.x (the introduction of newpcm). Full-duplex mmap still
doesn't work (due to VM/page design), but people still can mmap
both by opening each direction separately. mmaped playback is guarantee
to work either way.
- New sysctl: "hw.snd.compat_linux_mmap" to allow PROT_EXEC page
mapping, due to recent changes in linux compatibility layer which
require it. All linux applications that using sound + mmap() (mostly games)
require this to be enabled. Disabled by default.
- Other goodies.. too many, that will increase releng7 shareholder value
and make users of releng6 (and below) cry ;)
