1dfe405372 - Don't register the over-temperature and power-fail interrupt
handlers as filter/"fast" handlers so shutdown_nice() can
  acquire the process lock.
- Use bus_{read,write}_8() instead of bus_space_{read,write}_8()
  in order to get rid of sc_bushandle and sc_bustag in the softc.
- Remove the banal and outdated comment above sbus_filter_stub().

b42d5b0994 - Use the newly introduced pcib_mtx spin lock to lock psycho_ce(),
allowing it to be a filter/"fast" handler. Locking the interrupt
  handlers with a spin lock is mainly a requirement in schizo(4)
  but as we ought to register the spin lock anyway it should not
  hurt to take advantage of it in psycho(4).
- Pass both a driver_filter_t and a driver_intr_t argument to
  psycho_set_intr(), allowing to get rid of the FAST interrupt
  flag hack.
- Don't register the over-temperature interrupt handler as filter/
  "fast" handler so shutdown_nice() can acquire the process lock.
- Use bus_{read,write}_8() instead of bus_space_{read,write}_8()

- Correct the debug output for adjusting the subordinate bus number.
- Remove the banal and outdated above psycho_filter_stub().

7251b7863c Rather than passing SUSER_RUID into priv_check_cred() to specify when
a privilege is checked against the real uid rather than the effective
uid, instead decide which uid to use in priv_check_cred() based on the
privilege passed in.  We use the real uid for PRIV_MAXFILES,
PRIV_MAXPROC, and PRIV_PROC_LIMIT.  Remove the definition of
SUSER_RUID; there are now no flags defined for priv_check_cred().

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.
- Use a macro for the device description and take advantage of
  ISA_PNP_PROBE() setting the device description.
- Use the generated typedefs for the prototypes of the device
  interface functions.

a5a65afc6d Check for a NULL return from rpcclnt_buildheader- it can fail if
the passed in auth_type is unacceptable to rpcauth_buildheader-
this avoids a null pointer panic. Clean up allocations if this
happens. This also quiets a gcc 4.2 complaint about ussing mheadend
without it being initialized.

cb8bac4aee Correct state machine handling of AUTH -> AUTH transitions that pass
through wpa_supplcant.  If a sta is deauth'd (e.g. due to inactivity)
with roaming mode set to manual then a subsequent MLME assoc request
will be incorrectly handled and the station will never reauthenticate.
To fix this interpret a reason code of zero as sufficient to send an
auth request frame.

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.

Please note that, this is currently considered as an
experimental feature so there could be some rough
edges.  Consult http://wiki.freebsd.org/TMPFS for
more information.

For now, connect tmpfs to build on i386 and amd64
architectures only.  Please let us know if you have
success with other platforms.

This work was developed by Julio M. Merino Vidal
for NetBSD as a SoC project; Rohit Jalan ported it
from NetBSD to FreeBSD.  Howard Su and Glen Leeder

5915fb72fb Prototype (but functional) Linux-ish /dev/nvram interface to the extra
114 bytes of cmos ram in the PC clock chip.  The big difference between
this and the Linux version is that we do not recalculate the checksums
for bytes 16..31.

We use this at work when cloning identical machines - we can copy the
bios settings as well.  Reading /dev/nvram gives 114 bytes of data but
you can seek/read/write whichever bytes you like.

Yes, this is a "foot, gun, fire!" type of device.
