e42a0f5e72 - For sctp_input/sctp6_input add announcment when a packet arrives (debug)
- re-factor the packet drop in sctp_output a bit more, we don't need the
   trim after all, but the size calc is now corrected.
 - When a assoc is in the COOKIE-ECHO/COOKIE-WAIT state and the user
   closes, it should not matter if data is queued, the assoc should be

aa785996fd - Make better use of the global chosen, memory and mmu handles instead
of obtaining them over and over again and pretending we could do
  anything useful without them (for chosen this includes adding a
  declaration and initializing it in OF_init()).
- 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
  causes a hang. With OF_exit() one at least has a change to get back
  to the OFW boot monitor and debug the problem.
- Fix OF_call_method() on 64-bit machines (this is a merge of
  sys/dev/ofw/openfirm.c rev 1.6).
- Replace OF_alloc_phys(), OF_claim_virt(), OF_map_phys() and
  OF_release_phys() in the MI part of the loader with wrappers around
  OF_call_method() in the sparc64. Beside the fact that they duplicate
  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
  addresses.
- Remove unused functions which are also MD dupes of OF_call_method().
- In sys/boot/sparc64/loader/main.c add __func__ to panic strings as
  different functions use otherwise identical panic strings and make
  some of the panic strings a tad more user-friendly instead of just
  mentioning the name of the function that returned an unexpected
  result.

c6d76cdb21 - Add support for sending IPIs with USIII and greater sun4u CPUs.
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}()
  where not put into/moved to sys/sparc64/sparc64/{cheetah,spitfire}.c
- 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.

fdfba0e5ff - Flesh out the support for the EBus variant which actually is the
RTC function of a National Semiconductor PC87317/PC97317. This
  consists of using the century register the same way Solaris does
  for compatibility reasons. Once there is a MD power(4) we'd also
  want to interface the APC (Advanced Power Control) functionality
  of the same chip function with it.

2446e4f02c Enable the new physical memory allocator.
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.

e4e61333ff Last (again ?!?) major commit for RELENG_7, featuring total Giant
eradication in/from userland path, countless locking fixes, etc.

- General sleep call through msleep(9) has been converted to condvar(9)
  with better consistencies.
- 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.
- Anonymous mixer object creation/deletion to simplify mixer handling
  beyond typical mixer ioctls.
  Submitted by:		chibis (with modifications)
- 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 ;)

* This commit should be atomic. If anything goes wrong (not counting problem
  originated from elsewhere), I will not hesitate to revert everything back
  within 12 hours. This substantial changes itself not a rocket science
  and the process has begun for almost 2 years, and lots of incremental
  changes are already in place during that period of time.
* Some issues does occur in snd_emu10kx (note the 'x') due to various
  internal locking issues and it is currently being worked on by chibis.

458303da65 - Issue one, new stack reduction left packet_drop handling still
thinking it had the whole chunk. This could cause a crash if
  a large packet drop came in. Fixed by adjusting the trunc length
  down to the limit.
- Large sacks with lots of segments could also have same issue. Changed
  duplicate and segment handling to use proper get_m_ptr function to
  pull each block from mbuf chains.

5632c9822a - Conditionally pickup Giant around the network interface
ioctl routines if we are running with !mpsafenet
- Change un-conditional Giant acquisition around ifpromisc
  to occur only if we are running with !mpsafenet

With these locking bits in place, we can now remove the Giant
requirement from BPF, so drop the D_NEEDGIANT device flag.
This change removes Giant acquisitions around BPF device
handlers (read, write, ioctl etc).

7e273744a6 Remove the restriction that rtprio(2) cannot be used to set the realtime
or idle priority of another process owned by the same user.  This means
that privilege in rtprio(2) (and rtprio_thread(2)) is required indirectly
via p_cansched(9) or directly to set realtime/idle privilege, rather than
directly affecting target process authorization.

80fefe0a08 - Fix so ifn's are properly deleted when the ref count goes to 0.
- Fix so VRF's will clean themselves up when no references are around.
- Allow sctp_ifa to be passed into inpcb_bind, addr_mgmt_ep_sa to bypass
  normal validation checks.
- turn auto-asconf off for subset bound sockets
- Moves all logging to use KTR. This gets rid of most
  of the logging #ifdef's with a few exceptions reducing
  the number of config options for SCTP.

34a9edafbc Improve the ktrace locking somewhat to reduce overhead:
- Depessimize userret() in kernels where KTRACE is enabled by doing an
  unlocked check of the per-process queue of pending events before
  acquiring any locks.  Previously ktr_userret() unconditionally acquired
  the global ktrace_sx lock on every return to userland for every thread,
  even if ktrace wasn't enabled for the thread.
- Optimize the locking in exit() to first perform an unlocked read of
  p_traceflag to see if ktrace is enabled and only acquire locks and
  teardown ktrace if the test succeeds.  Also, explicitly disable tracing
  before draining any pending events so the pending events actually get
  written out.  The unlocked read is safe because proc lock is acquired
  earlier after single-threading so p_traceflag can't change between then
  and this check (well, it can currently due to a bug in ktrace I will fix
  next, but that race existed prior to this change as well).
