Add a simplebus attachment for cfi(4)'s FDT support and move
cfi_bus_fdt.c to sys/conf/files so non-ppc architectures are supported.

Replace ln -fhs with ${INSTALL_SYMLINK} to the link is logged in the
METALOG.
- netmap_rx_irq()/netmap_tx_irq() can now be called by FreeBSD drivers
hiding the logic for handling NIC interrupts in netmap mode.
This also simplifies the case of NICs attached to VALE switches.
Individual drivers will be updated with separate commits.
- use the same refcount() API for FreeBSD and linux
- plus some comments, typos and formatting fixes

those of some non-architectural core events. This is not a problem in the
general case as long as there's an 1:1 mapping between the two, but there
are few exceptions. For example, 3CH_01H on Nehalem/Westmere represents
both unhalted-reference-cycles and CPU_CLK_UNHALTED.REF_P.
CPU_CLK_UNHALTED.REF_P on the aforementioned architectures does not measure
reference (i.e. bus) but TSC, so there's the need to disambiguate.
In order to avoid the namespace collision rename all the architectural
events in a way they cannot be ambigous and refactor the architectural
events handling function to reflect this change.
While here, per Jim Harris request, rename
iap_architectural_event_is_unsupported() to iap_event_is_architectural().

A blocking accept (and some other operations) waits on &so->so_timeo. Once
it wakes up, it will detect the SBS_CANTRCVMORE bit.
The error from accept() is [ECONNABORTED] which is not the nicest one -- the
thread calling accept() needs to know out-of-band what is happening.
A spurious wakeup on so->so_timeo appears harmless (sleep retried) except
when lingering on close (SO_LINGER, and in that case there is no descriptor
to call shutdown() on) so this should be fairly safe.
A shutdown() already woke up a blocked accept() for TCP sockets, but not for
Unix domain sockets. This fix is generic for all domains.
This patch was sent to -hackers@ and -net@ on April 5.

properly deallocate structures in case CPU claims that hw performance
monitoring counters are not supported.

The NTB allows you to connect two systems with this device using a PCI-e
link. The driver is made of two modules:
- ntb_hw which is a basic hardware abstraction layer for the device.
- if_ntb which implements the ntb network device and the communication
protocol.
The driver is limited at the moment to CPU memcpy instead of using DMA, and
only Back-to-Back mode is supported. Also the network device isn't full
featured yet. These changes will be coming soon. The DMA change will also
bring in the ioat driver from the project branch it is on now.
This is an initial port of the GPL/BSD Linux driver contributed by Jon Mason
from Intel. Any bugs are my contributions.
