Use logic or, not binary or, when deciding whether or not a system call
exit requires entering the audit code. The result is much the same,
but they mean different things.

Factor out the v4-only vs. the v6-only inp_flags processing in
ip6_savecontrol in preparation for udp_append() to no longer
need an WLOCK as we will no longer be modifying socket options.
Move IFF_NEEDSGIANT warning from if_ethersubr.c to if.c so it is displayed
for all network interfaces, not just ethernet-like ones.
Upgrade it to a louder WARNING and be explicit that the flag is obsolete.
Support for IFF_NEEDSGIANT will be removed in a few months (see arch@ for
details) and will not appear in 8.0.
MFC r180738:
Do the pargs_hold() on the copy of the pointer to the p_args of the
child process immediately after bulk bcopy() without dropping the
process lock.
After the commit of SVN rev 180236, wilko@ noticed that the approach
doesn't work on the Alpha platform: machine/elf.h doesn't include
sys/elf32.h there.

MFC r179365 to stable/7:
- Increase the size of the salt in pw(8) from 8 to 32 (same as in pam_unix(8)).
This makes blowfish password hashes look normal when set using
pw(8)/adduser(8). [1]
- Make it possible to have a '/' in the salt.
Since we create a DMA tag "mtag" for TX map with bus_dmamap_create(),
we must synchronize such a map against "mtag" with bus_dmamap_sync(),
not the tag designated for RX map.
Don't let hacksync() call bus_dmamap_sync(9) on DMA maps which
are not initialized. This fixes a panic on sparc64 where calling
bus_dmamap_sync(9) on NULL DMA maps is fatal.
Refactor certain ARM bus space methods: instead of having multiple copies of
the same code introduce sys/arm/arm/bus_space_generic.c for a shared set of
routines.
Take the first baby step towards unifying and cleaning up arminit():
- Pull all the code to deal with the trampoline stuff into one
centeralized place and use it from everywhere.
- Some minor style tidiness
KERNBASE + 0x00200000 is the same thing as KERNVIRTADDR on this
platform, so use the latter in preference to the former. This makes
the fake_preload setup be the same between kb920x_machdep.c and
avila_machdep.c....
Improve mac+phy configuration so that hints can be used to describe
layouts different than the defaults:
o hint.npe.0.mac="A", "B", etc. specifies the window for MAC register accesses
o hint.npe.0.mii="A", "B", etc. specifies PHY registers
o hint.npe.1.phy=%d specifies the PHY to map to a port
Workaround design botch in usb: blindly mixing bus_dma with PIO does not
work on architectures with a write-back cache as the PIO writes end up
in the cache which the sync(BUS_DMASYNC_POSTREAD) in usb_transfer_complete
then discards; compensate in the xfer methods that do PIO by pushing the
writes out of the cache before usb_transfer_complete is called.
Correct cache handling for xfer requests marked URQ_REQUEST: many (if not
all uses) involve a read but usbd_start_transfer only does a PREWRITE; change
this to BUS_DMASYNC_PREREAD | BUS_DMASYNC_PREWRITE as I'm not sure if any
users do write+read.
Correct the logic : we can just invalidate the cache lines, and not
write-back them, only if PREWRITE is not set, and if the buffer is
cache-line aligned.
Merge r180610, r180616, r180673 from head to stable/7:
Add DDB "show conifhk" command, which lists hooks currently waiting
for completion in run_interrupt_driven_config_hooks(). This is
helpful when trying to figure out which device drivers have gone
into la-la land during boot-time autoconfiguration.
Rather than simply waiting silently and indefinitely for all
interrupt-driven configuration handlers to complete, print out a
diagnostic message every 60 second indicating which handlers are
still running. Do this at most 5 times per run so as to avoid
scrolling out any useful information from the kernel message
buffer.
The interval of 60 seconds was selected based on a best guess as
to the nature of "long enough" and may want to be tuned higher
or lower depending on real-world tolerances.
If run_interrupt_driven_config_hooks() waits 360 seconds and INVARIANTS
is compiled into the kernel, then panic.
Add -m option to cron(8), overriding default mail recipient for cron
mails, unless explicitly provided by MAILTO= line in crontab. This
feature can be useful in massive hosting environment, where most users
do not care about autogenerated mails.
Setting recipient to null string disables default mails at all.
Although being recorded as MFC of the r177369, this change was
introduced for the KSE case in the r177083. Both were done by jeff,
MFC is needed due to recent cpuset(2) commit to RELENG_7.
r177083:
KSE may free a thread that was never actually forked. This will leave
td_cpuset NULL. Check for this condition before dereferencing the
cpuset.
r177369:
Restore the NULL check for td_cpuset. This can happen if a partially
constructed thread was torn down as is the case when we fail to allocate
a kernel stack.
