acpi/pcib: Rework the _BBN handling for Host-PCI bridges.
Obtained-from: FreeBSD (Revision 193829 by jhb@freebsd.org)
Previously we only trusted a _BBN value of 0 if it was for the first
bridge encountered since some older systems returned _BBN of 0 for
all bridges. However, some newer systems enumerate bridges with
non-zero _BBN before bus 0 which is perfectly valid. Handle both
cases by trusting the first bridge that has a _BBN of 0 and falling
back to reading from non-standard config registers only for
subsequent bridges with a _BBN of 0. We also only perform this
check for segment (domain) 0. We assume that _BBN is always correct
for segments other than 0.

bus: Allow subclass to have the same name as the parent class.
Obtained-from: FreeBSD (Revision 154598 by jhb@freebsd.org)
When loading a driver that is a subclass of another driver don't set the
devclass's parent pointer if the two drivers share the same devclass. This
can happen if the drivers use the same new-bus name. For example, we
currently have 3 drivers that use the name "pci": the generic PCI bus
driver, the ACPI PCI bus driver, and the OpenFirmware PCI bus driver. If
the ACPI PCI bus driver was defined as a subclass of the generic PCI bus
driver, then without this check the "pci" devclass would point to itself
as its parent and device_probe_child() would spin forever when it
encountered the first PCI device that did have a matching driver.

binutils221: revisit start/stop label generation
In commit
b133d3fde203bbf8e2c359d2be9f09c20ce732b5 (3 April), ld's
lang_insert_orphan function was modified to include all symbols, which
matches the behavior of binutils 2.17 and allowed kernel modules
utilizing previously unreferenced __start_* and __stop_* sections to
load properly.
For at least 4 years, the ld developed by binutils has the policy to
discard all unreference symbols, considering them "clutter". This
commit will revert back ld back to its default behavior unless the
options -shared or -Bshareable are passed in the command line. In those
cases, the linked file will include all symbols, referenced or not.
In the future, we may consider modifying an .em file to define a flag
that will revert to 2.17 on a per-target basis rather than forcing all
shared objects to carry extraneous symbols. I'd have to identify all
kernel modules requiring this flag before implementing that change.

vm.swapcache.data_enable=1

* This allows swapcache to more efficiently cache file data without
vnode recycling from a limited kern.maxvnodes value getting in the way.
If you have a large dataset spread across many smaller files which would
normally overwhelm maxvnodes, and even on large systems handling very
large data sets where you wish to cache the file data for some of the
files (using use_chflags=1 mode), this makes it possible to cache ALL
the file data AND meta-data on the SSD even though the related vnodes
cached by the kernel get recycled.
* Whereas it may have been inefficient to turn on vm.swapcache.data_enable
before, due to filesystem scans and such, it may now be possible to this
feature on with double buffering also enabled.
Note that you must still be cognizant of the aggregate amount of file
data being accessed by your system if you have set use_chflags to 0, you
simply no longer need to worry about how many files that data belongs to.

root (typically the lowest path cost of all the target bridge's

for it instead of the assembly switch code. Adjust td->td_switch() to
return the previously running thread.
This allows lwkt_switch() to process thread migration between cpus after
the thread has been completely and utterly switched out, removing the
need to loop on TDF_RUNNING on the target cpu.
* Fixes lwkt_setcpu_remote livelock failure
* This required major surgery on the core thread switch assembly, testing
is needed. I tried to avoid doing this but the livelock problems persisted,
so the only solution was to remove the need for the loops that were causing
the livelocks.
* NOTE: The user process scheduler is still using the old giveaway/acquire
method. More work is needed here.
