o When detaching all children, try really hard to get all the children
list before giving up. This is based on an observation by hans petter
selasky in his usb p4 branch.
o When rescanning devices after a driver is added, abort if we can't get
the child list with a message.
o when rescanning devices, if the reprobe/attach is successful, save the
device for cardbus/pccard.
Unlike other GigEs Yukon II always set VLAN bit when it detects VLAN
tagged packet regardless of H/W VLAN processing configuration state.
So it need to check IFCAP_VLAN_HWTAGGING bit to know whether driver
is configured to take advantage of H/W VLAN processing. If H/W VLAN
processing was disabled don't adjust received packet length such that
subsequent validation logic works for software VLAN processing.

vm_page_free_toq() to account for recent changes that allow
vm_page_free_toq() to be called on some pages without the page queues lock
being held, specifically, pages that are not contained in a vm object and
not a member of a page queue. (Examples of such pages include page table
pages, pv entry pages, and uma small alloc pages.)
- PROT_READ, PROT_WRITE, or PROT_EXEC implies PROT_READ and PROT_EXEC.
Linux/ia64's i386 emulation layer does this and it complies with Linux
header files. This fixes mmap05 LTP test case on amd64.
- Do not adjust stack size when failure has occurred.
- Synchronize i386 mmap/mprotect with amd64.
blacklist a bunch of old chipsets. If a system contains a PCI-PCI bridge
that supports PCI-X, assume the chipset supports PCI-X. If a system
contains a PCI-express root port, assume the chipset supports PCI-express.
If the chipset doesn't support either PCI-X or PCI-express, then blacklist
it by default. We should now only need to explicitly blacklist PCI-X or
PCI-express chipsets that don't properly handle MSI.
broke the method as all the MSI-X table indices were off by one in
the backend MD code.
- Fix a cosmetic nit in the bootverbose printf in pci_alloc_msix_method().
Without -n, we now only print a "network name" without the prefix length
under the following conditions:
1) the network address and mask matches a classful network prefix;
2) getnetbyaddr(3) returns a network name for this network address.
With -n, we unconditionally print the full unabbreviated CIDR network
prefix in the form "a.b.c.d/p". 0.0.0.0/0 is still printed as "default".
This change is in preparation for changes such as equal-cost multipath, and
to more generally assist operational deployment of FreeBSD as a modern IPv4
router. There are currently no plans to backport this change.

sonewconn() in unp_connect(). This avoids a race that occurs due to
v_socket being an uncounted reference, as the lock was being released in
order to call sonewconn(), which otherwise recurses into the UNIX domain
socket code via pru_attach, as well as holding the lock over a sleeping
memory allocation in uipc_attach(). Switch to a non-sleeping memory
allocation during UNIX domain socket attach.
This fix non-ideal in that it requires enabling recursion, but is a much
smaller change than moving to using true references for v_socket. The
reported panic occurs in unp_connect() following the return of
sonewconn().

Libarchive recently changed to correctly return the amount

bug in bsdtar.
is actually being added to the hold queue, not the free queue. At the same
time, avoid unnecessary tests to wake up threads waiting for free memory
and the idle thread that zeroes free pages. (These tests will be performed
later when the page finally moves from the hold queue to the free queue.)
observation here is that it doesn't matter what garbage accumulates in
bits which we're going to end up masking away anyway, as long as the
garbage doesn't overflow into bits which we care about.
This improved version may not be the fastest possible on all systems,
but it's certainly going to be better than what was here before.
- Add sigacts locking.
- Add a mutex to struct sigacts that protects all the members of the struct.
- Create and log events via the CTRx macros.
