not ACPI-specific at all, but deal with PCI power states. Also,
pci_set_powerstate() fails with EOPNOTSUPP if a request is made that the
underlying device does not support rather than falling back to somehow
setting D0.
pci_cfg_save() and pci_cfg_restore() for device drivers to use when
saving and restoring state (e.g. to handle device-specific resets).

installs clang as /usr/bin/cc, /usr/bin/c++ and /usr/bin/cpp.
Note this does *not* disable building and installing gcc, which will
still be available as /usr/bin/gcc, /usr/bin/g++ and /usr/bin/gcpp. If
you want to disable gcc completely, you must use WITHOUT_GCC.

get rid of testing explicitly for clang (using ${CC:T:Mclang}) in
individual Makefiles.
Instead, use the following extra macros, for use with clang:
- NO_WERROR.clang (disables -Werror)
- NO_WCAST_ALIGN.clang (disables -Wcast-align)
- NO_WFORMAT.clang (disables -Wformat and friends)
- CLANG_NO_IAS (disables integrated assembler)
- CLANG_OPT_SMALL (adds flags for extra small size optimizations)
As a side effect, this enables setting CC/CXX/CPP in src.conf instead of
make.conf! For clang, use the following:
CC=clang
CXX=clang++
CPP=clang-cpp

USERSPACE:
1. add support for devices with different number of rx and tx queues;
2. add better support for zero-copy operation, adding an extra field
to the netmap ring to indicate how many buffers we have already processed
but not yet released (with help from Eddie Kohler);
3. The two changes above unfortunately require an API change, so while
at it add a version field and some spares to the ioctl() argument
to help detect mismatches.
4. update the manual page for the two changes above;
5. update sample applications in tools/tools/netmap
KERNEL:
1. simplify the internal structures moving the global wait queues
to the 'struct netmap_adapter';
2. simplify the functions that map kring<->nic ring indexes
3. normalize device-specific code, helps mainteinance;
4. start exploring the impact of micro-optimizations (prefetch etc.)
in the ixgbe driver.
Use 'legacy' descriptors on the tx ring and prefetch slots gives
about 20% speedup at 900 MHz. Another 7-10% would come from removing
the explict calls to bus_dmamap* in the core (they are effectively
NOPs in this case, but it takes expensive load of the per-buffer
dma maps to figure out that they are all NULL.
Rx performance not investigated.
I am postponing the MFC so i can import a few more improvements
before merging.
- Remove all attempts to guess physical temperature using DiodeOffset.
There are too many reports that it varies wildly depending on motherboard.
Instead, if it is known to scale well and its offset is known from other
temperature sensors on board, the user may set "dev.amdtemp.0.sensor_offset"
tunable to compensate the difference. Document the caveats in amdtemp(4).
- Add a quirk for Socket AM2 Revision G processors. These processors are
known to have a different offset according to Linux k8temp driver.
- Warn about Family 10h Erratum 319. These processors have broken sensors.
- Report temperature in more logical orders under dev.amdtemp node. For
example, "dev.amdtemp.0.sensor0.core0" is now "dev.amdtemp.0.core0.sensor0".
- Replace K8, K10 and K11 with official processor names in amdtemp(4).
- Convert to our standard SYNOPSIS language
- Consistently use "The .Nm driver"
- Rewrite .nf .fi block with mdoc
- Add pci dependency to SYNOPSIS
- Start .Bl list with new paragraph

Extend the so far IPv4-only support for multiple routing tables (FIBs)
introduced in r178888 to IPv6 providing feature parity.
This includes an extended rtalloc(9) KPI for IPv6, the necessary
adjustments to the network stack, and user land support as in netstat.

1. Add new functionality to the force_depend method to incorporate the
tests for whether the service is enabled and/or already running.
2. Add a new option to bypass checking only that the service is enabled
at boot time, and always check if it is running.
3. Use this new functionality to greatly simplify the rc.d scripts that
use force_depend.
4. Add a force_depend for statd in lockd
5. Remove the check that either nfs_server or nfs_client is _enable'd
from statd and lockd. This was always overkill, and prevented using
the {one|force}start options, as well as stop'ing on the command line.
6. The yp* scripts had some of their arguments in various weird orders.
Bring them into line with the model.
7. If mountd fails to create /var/db/mountdtab, err out.
Ideas, suggestions, and/or review from delphij and jilles.
Pointy hats are completely my responsibility however.
The reasoning behind this, is that if we are consistent in our
documentation about the uint*_t stuff, people will be less tempted to
write new code that uses the non-standard types.
I am not going to bump the man page dates, as these changes can be
considered style nits. The meaning of the man pages is unaffected.
