- Rename pmc.mips to pmc.mips24k since it covers just one CPU,
no whole architecture
- Add documetnations for Octeon's PMC counters
- Remove CAVEATS section from pmc.mips24k page: PMC for MIPS supports
sampling now.
- Updates to various locations in Antarctica.
- Armenia will abolish DST this year.
- Not only Samoa has moved to UTC+14, also Fakaofo did.
- There will be a leap second in 30 June 2012.
- Historical updates of 1918 to Canada, Winn, Regina, Edm, Vanc, Creston.
- Chili stays on DST until 28 April 2012
- The Falkland islands will stay on DST this year.
- Add an examples file with many of the not accepted suggestions from the discussion

According to some private emails received, it apparently is not unpopular
to use at least Quad GigaSwift cards driven by cas(4) in x86 machines.

order to avoid otherwise harmless witness warnings when these are acquired
at the same time and due to both using MTX_NETWORK_LOCK as their type.
The right fix actually would be to use different, descriptive types for
these. However, the latter would require undesirable changes to the shared
code base. Another approach would be to just supply NULL as the type, which
was deemed as less desirable though as it would cause the unique but cryptic
name also to be used for the type and to diverge from the type used by other
network device drivers.

DMA tag with a 4 GB boundary as required by PCI-Express. With r232403 in
place this actually is redundant. However, the host-PCI-Express bridge
driver is the more appropriate place for implementing this restriction.

recent changes in sys/x86/include/endian.h:
sys/dev/dcons/dcons.c:190:15: error: implicit conversion from '__uint32_t' (aka 'unsigned int') to '__uint16_t' (aka 'unsigned short') changes value from 1684238190 to 28526 [-Werror,-Wconstant-conversion]
buf->magic = ntohl(DCONS_MAGIC);

#define ntohl(x) __ntohl(x)

./x86/endian.h:128:20: note: expanded from:

__bswap16_gen((__uint16_t)(x)) : __bswap16_var(x)))
~~~~~~~~~~~~~ ^
This is because the __bswapXX_gen() macros (for x86) call the regular
__bswapXX() macros. Since the __bswapXX_gen() variants are only called
when their arguments are constant, there is no need to do that constancy
check recursively. Also, it causes the above error with clang.
Fix it by calling __bswap16_gen() from __bswap32_gen(), and similarly,
__bswap32_gen() from __bswap64_gen().
While here, add extra parentheses around the __bswap16_gen() macro
expansion, to prevent unexpected side effects.
- header and stub .c file for fasttrap module. It's not supported on
MIPS yet, but there is no way to disable support completely
- Do as amd64 trying to limit allocated memory
CTF format is not cross-platform by design, e.g. it is not guaranteed
that data generated by ctfconvert/ctfmerge on one architecture will
be successfuly read on another. CTF structures are saved/restored
using naive approach. Roughly it looks like:
write(fd, &ctf_struct, sizeof(ctf_struct))
read(fd, &ctf_struct, sizeof(ctf_struct))
By sheer luck memory layout of all type-related CTF structures is the same
on amd64/i386/mips32/mips64. It's different on ARM though. sparc, ia64,
powerpc, and powerpc64 were not tested. So in order to get file compatible
with dtrace on ARM it should be compiled on ARM. Alternative solution would
be to have "signatures" for every platform and ctfmerge should convert host's
reperesentation of CTF structure to target's one using "signature" as template.
This patch checks byte order of ELF files used for generating CTF record
and makes sure that byte order of data written to resulting files is the same
as target's byte order.
Note that this driver additionally probes some device IDs for the most
part not know to other MPT drivers, if at all. So rename the macros not
present in mpi_cnfg.h to match the naming scheme in the latter and but
suffix them with a _FB in order to not cause conflicts.
- Like mpt_set_config_regs(), comment out mpt_read_config_regs() as the
content of the registers read isn't actually used and both functions
aren't exactly up to date regarding the possible layouts of the BARs
(these function might be helpful for debugging though, so don't remove
them completely).
- Use DEVMETHOD_END.
- Use NULL rather than 0 for pointers.
- Remove an unusual check for the softc being NULL.
- Remove redundant zeroing of the softc.
- Remove an overly banal and actually partly incorrect as well as partly
outdated comment regarding the allocation of the memory resource.

Unfortunately, the ABI was broken upstream for the 4.2 release, which we
imported. We then shipped the broken version for several years and certain
ports (e.g. libobjc2) depend on it, so we're stuck with it for now...
We should revisit this for 10.0, since we're allowed to break the ABI then, but
until then we should keep the ABI we shipped with 8.x and 9.x.
