21cf0e3907 MFp4: fix two locking problems:
- Hold TMPFS_LOCK while updating tm_pages_used.
 - Hold vm page while doing uiomove.

This will hopefully fix all known panics.

7faa61e65d Track whether the current read stream supports seek(). For now, we
assume yes unless seek has previously failed, but I fear I'll have to
avoid seeks under other circumstances.  (For instance, tape drives on
FreeBSD seem to return garbage from lseek().)  Also, optimize away
zero-byte skips.

7e990b09e2 Apply a vendor patch that fixes very annoying bug
which caused the cursor not to return to the place
it should when -w is used with -e.

Note that this is a commit against -HEAD because
we already have the file off the vendor branch.

0081f96ecd Have gpart synthesize a disk geometry if the underlying provider
don't have it. Some partitioning schemes, as well as file systems,
operate on the geometry and without it such schemes (e.g. MBR)
and file systems (e.g. FAT) can't be created. This is useful for
memory disks.

d83e603ac7 Silence some gcc 4 warnings. It is expected that the bpf_movein() routine
will intialize the the header length and re-initialize the mbuf pointer
to reference the mbuf that is allocated after moving user supplied packet
data in.

d933824786 Fix a (very) longstanding bug in moused(8) affecting high-resolution rodents
when linear acceleration (-a) was enabled with a <1 value to slow them down.

Previously, rounding errors would eat small movements so the mouse had to be
moved a certain distance to get any movement at all.  We now calculate the
rounding errors and take them into account when reporting movement.

75298de2a0 Back out last change to inpcb_free. Turns out we need
to hold off freeing if there is data pending ... someone
might do send/close. Which means we want the data to
go and then close it after startup. Added comments to
the code as well to note that this is done for a reason.

997c6eefd8 Add PAM support to cron(8). Now cron(8) will skip commands scheduled
by unavailable accounts, e.g., those locked, expired, not allowed in at
the moment by nologin(5), or whatever, depending on cron's pam.conf(5).
This applies to personal crontabs only, /etc/crontab is unaffected.

In other words, now the account management policy will apply to
commands scheduled by users via crontab(1) so that a user can no
longer use cron(8) to set up a delayed backdoor and run commands
during periods when the admin doesn't want him to.

The PAM check is done just before running a command, not when loading
a crontab, because accounts can get locked, expired, and re-enabled
any time with no changes to their crontabs.  E.g., imagine that you
provide a system with payed access, or better a cluster of such
systems with centralized account management via PAM.  When a user
pays for some days of access, you set his expire field respectively.
If the account expires before its owner pays more, its crontab
commands won't run until the next payment is made.  Then it'll be
enough to set the expire field in future for the commands to run
again.  And so on.

Document this change in the cron(8) manpage, which includes adding
a FILES section and touching the document date.

X-Security: should benefit as users have access to cron(8) by default

eb988b9d42 Use bus_dma to get a page in the first 4 GB. Since the physical address
of the magic string is passed in a 32-bit register, we can't use high
memory in the PAE case.  This also eliminates a use of vtophys().

b50569b71d Prepare for future integration between CAM and newbus. xpt_bus_register
now takes a device_t to be the parent of the bus that is being created.
Most SIMs have been updated with a reasonable argument, but a few exceptions
just pass NULL for now.  This argument isn't used yet and the newbus
integration likely won't be ready until after 7.0-RELEASE.

bb38cd2fbc - switch adapter and port lock over to using sx so that resources
can be allocated atomically
- add debug macros for printing lock initialization / teardown
- add buffers to port_info and adapter to allow each lock to have a
  unique name
- destroy mutexes initialized by cxgb_offload_init
- remove recursive calls to ADAPTER_LOCK
- move callout_drain calls so that they don't occur with the lock held
- ensure that only as many qsets as are needed are initialized and
  destroyed

9ba2645aa7 Fix build on arm: time_t on arm is 64 bits while long is
32 bits, so subsequent compile time assertion:

	sizeof inf->stat.st_mtime <= sizeof sec

Would fail because of that.  This change is suitable for
general consumption as well, but fix it in our local
patchset as we are near a code freeze.

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.

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/
