"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.
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.

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.
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.

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.

Without bus_dma clean up and increment of number of Tx descriptors
it's hard to guarantee correct Tx operation in TSO case. The TSO
support would be enabled again when I get more feeback from re(4)
patch posted to current.
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.

'result' is still NULL and we do not need to free anything.
That allows us to gc the entire goto parts and a now unused variable.

I cannot see why we should always return 0 there. Neither does KAME

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.

- In tdq_choose() only assert that a thread does not have too high a
priority (low value) for the queue we removed it from. This will catch
bugs in priority elevation. It's not a serious error for the thread
to have too low a priority as we don't change queues in this case as
an optimization.
