devd.conf execution of third-party software, that needs libraries
from /usr/local. Since devd is launched before ldconfig script, if
the hardware that has associated software is attached on boot, then
execution would fail.

The old comment in zfs_rezget explains what situation the code handles,
the new comment also describes how the situation can arise.
Also, re-join a line that became sufficiently shorti some time ago.

/dev/zfs always has per-open data, so when it is missing the file
descriptor is for some other file. Returning ENOENT in this case
is confusing as a variety of other conditions (like a missing dataset)
may result in the same error. It's better to consistently return
EBADF for any problems with the file descriptor.
Note that zfs_onexit_fd_hold() is used with 'automatic cleanup fd'
- when that fd is closed, typically because a process is terminated,
some cleanup action is taken by ZFS driver. E.g. a temporary
snapshot hold is released.
Perhaps, it would even be worthwhile changing devfs_get_cdevpriv()
to return EBADF if there is no associated data.

1) Advertise the actual min / max speeds the hardware is capable
of supporting given the reference clock used by the board.
2) Rather than attempting to extend the hardware's timeout register
in software (the hardware doesn't have sufficient bits to directly
support long timeouts), simply implement the same timeout approach
used in the SDXC driver.
3) Set the timeout for a linked command (e.g. STOP TRANSMISSION) based
on the previous multiblock read / write.
The changes have been smoke tested on both the ODROID-C1 and the VSATV102-M6
using the following cards:
* PQI 2GB microSD
* SanDisk 2GB microSD
* PQI 8GB SDHC (not a microSD so only tested on the ATV-102)
* PNY 8GB microSDHC
* SanDisk Ultra 32GB microSDHC

pages which pass a NULL virtual address. If the BUS_DMA_KEEP_PG_OFFSET
flag is set, use the physical address to compute the page offset
instead. The physical address should always be valid when adding
bounce pages and should contain the same page offset like the virtual
address.

This is not likely to make it into a release and is basically disabled

ACPI C3 ends up doing a lot more work before entering sleep, some of which
requires grabbing a global ACPI hardware serialising mutex.
Because of this, the more CPU cores you have, the more that lock contends
under load, reaching close to the #1 lock contention (after VM, which is being
worked on.)
Tested:
* Sandy bridge Xeon, 2 socket * 8 core
* Ivy bridge Xeon v2, 2 socket * 8 core
* Westmere-EX, 4 socket * 10 core
* Ivybridge desktop
* Sandybridge mobile

According to standard, the presence of the flags only means that the
object path must be resolved at the time object loading, instead of my
reading that the flag is required to enable token substitution at all.
The consequence is that -z origin linker flag is no longer required
for the token substitution in the run/rpath or the needed library
soname. It is only recommended if token substition is needed at
dlopen(3) time, since namecache might drop the required entries at the
time of resolution.

All architectures on FreeBSD have the necessary support though, so the

Run configure for drill (I forgot to do it when I imported 1.6.17, but the
omission was harmless). Note that running configure --with-drill at the
top level doesn't quite work for us since it is geared toward the slightly
weird upstream Makefiles, which we don't use.

bufdaemon in getnewbuf(), do use buf_flush(). The difference is that
bufdaemon uses TRYLOCK to get buffer locks, which allows calls to
getnewbuf() while another buffer is locked.
