BAR could be allocated twice by different children of a vgapci0 device.
To fix this, change the vgapci0 device to track references on its associated
resources so that they are only allocated once from the parent PCI bus and
released when no children are using them. Previously this leaked a small
amount of KVA on at least some architectures.
into the advance_peer_ack point so we would incorrectly
send a wrong value in the FWD-TSN
- PR-SCTP bug, where an PR packet is used for a window
probe which could incorrectly get the packet moved
back into the send_queue, which will cause major issues and
should not happen.
- Fix a trace to use the proper macro.
Because of integer promotion, Clang doesn't allow ANSI prototypes to be
mixed with K&R declarations.

We now explicitly enable INTx during bus_setup_intr() if it is needed.
Several of the ata drivers were managing this bit internally. This is
better handled in pci and it should work for all drivers now.
We also mask INTx during bus_teardown_intr() by setting this bit.

We fail mapping for any udf_bmap_internal error and there can be
different reasons for it, so no need to (over-)emphasize files with
data in fentry.

and do not attempt to perform a group lookup.
This is a socket layer lock, and the bottom half of IP
really has no business taking it.
Use the value of the in_mcast_loop sysctl to determine
if we should loop back by default, in the absence of
any multicast socket options. Because the check on
group membership is now deferred to the input path,
an m_copym() is now required.
This should increase multicast send performance where the
source has not requested loopback, although this has not been
benchmarked or measured.
It is also a necessary change for IN_MULTI_LOCK to become
non-recursive, which is required in order to implement IGMPv3
in a thread-safe way.
IPv4 multicast sends are looped back to senders by default
on a stack-wide basis, rather than relying on the socket option.
Note that the sysctl only applies to newly created multicast sockets.
dprintf() is a simple wrapper around another function, so we may as
well implement it. But also like getline(), we can't prototype it by
default right now because it would break too many ports.
*at, and fexecve to the POSIX.1-2008 namespace.
- Remove getwd, ualarm, usleep, and vfork from the XSI namespace.
- Remove mkdtemp from the POSIX.1-2008 namespace (should be in stdlib.h).
- Added missing firmware for 5709 A1 controllers.
- Changed some debug statistic variable names to be more consistent.

while developing and compiling with kernel options that change the
size of at least one structure. The current kernel build framework
does not allow us to pass -Dxxx to module builds so we would possibly
need a kernel option to disable the checks and that might not work
for people just building modules alone.
For now they helped to identify possibly API problems and bring
those back into minds of developers seeking for better solutions.
