only supports a single adapter rather than the various PCI adapters listed.
The list of EISA adapters listed somewhat overlaps with the device IDs in
dpt_eisa.c. It's not clear which devices are ISA-only devices.

kern_openat().
This removes one (sometimes two) levels of indirection and
consolidates arguments checks.

leave a port permanently disabled when a copper cable is unplugged and
then plugged right back in.
lacp_linkstate goes looking for the current ifmedia on a link state
change and it could get stale information from cxgbe(4) on a module
unplug followed by replug. The fix is to process module events before
link-state events within the driver, and to always rebuild the ifmedia
list on a module change event (instead of rebuilding it lazily).
Thanks to asomers@ for the problem report and detailed analysis to go
with it.

Instead of waiting for empty TX FIFO it is more reasonable to
block on full FIFO. As soon as FIFO slot is free the character
can be transmitted.
In case of TX FIFO disabled, TXFF bit indicates that transmit
register is not empty.

Totally forget deallocated SDNodes in SDDbgInfo.
What would happen before that commit is that the SDDbgValues associated with
a deallocated SDNode would be marked Invalidated, but SDDbgInfo would keep
a map entry keyed by the SDNode pointer pointing to this list of invalidated
SDDbgNodes. As the memory gets reused, the list might get wrongly associated
with another new SDNode. As the SDDbgValues are cloned when they are transfered,
this can lead to an exponential number of SDDbgValues being produced during
DAGCombine like in http://llvm.org/bugs/show_bug.cgi?id=20893
Note that the previous behavior wasn't really buggy as the invalidation made
sure that the SDDbgValues won't be used. This commit can be considered a
memory optimization and as such is really hard to validate in a unit-test.
This should fix abnormally large memory usage and resulting OOM crashes
when compiling certain ports with debug information.

I originally overlooked a couple flag bits defined in the fdt binding docs.
One flag suppresses the pad configuration (pullup/pulldown/etc). The other
one requires that the SION (set input on) flag be set in the mux register.
Also, it appears from the data involved that if the input register
address in the config tuple is zero, there is no input configuration. The
old code was writing to register zero, which contains a collection of misc
control bits (having nothing to do with input configuration) that probably
shouldn't get overwritten arbitrarily. The bindings doc doesn't explictly
mention this.
with 128K of random data and truncated to 800K can have SEEK_DATA return -1
when given an offset of 128K. On UFS, the SEEK_DATA returns 800K (the size
of the file). SEEK_HOLE on ZFS seems to behave the same as UFS.
To handle this, map -1 to the size of the file (`end') when lseek returns
this for either SEEK_HOLE or SEEK_DATA. When sparse files are not supported
by the file system both `hole' and `data' will now be equal to `end' and we
will treat the entire file as data. This way, the -1 return for SEEK_DATA
on ZFS will end up doing the right thing.

that expose new bugs with HS mode.
When the old code could not do the proper card detection it would boot with
lower defaults (and no HS mode) and this makes some HS cards boots.
Now, with the card always identified as HS capable, the sdhci controller
tries to run the card at HS speeds and makes the boot always fail.
Disable the HS mode for now (which still can be enabled with the tunable)
until it is properly fixed.

The various structures in the mod_metadata set of a FreeBSD kernel and
modules contain pointers. The FreeBSD loader correctly deals with a
mismatch in loader and kernel pointer size (e.g. 32-bit i386/ppc
loader, loading 64-bit amd64/ppc64 kernels), but wasn't dealing with
the inverse case where a 64-bit loader was loading a 32-bit kernel.
