bcma: reject PCI cards in bcma.

bcma currently only supports PCIe cards and no PCI cards, reject them
if we find them. I have never heard of any PCI card using the AI bus
(bcma), all of them are using ssb instead.

rt2x00_pci: Fix interrupt handler name (visible at /proc/interrupts)

Currently driver name is wrong. PCI device address is visible at
/proc/interrupts instead of the name:

 43:    124      0      0      0   PCI-MSI-edge    rtsx_pci
 44:    384      0      0      0   PCI-MSI-edge    snd_hda_intel
 45:  25096      0      0      0   PCI-MSI-edge    0000:01:00.0
                                                   ^^^^^^^^^^^^

So, pass the right name. rt2x00_ops->name contains KBUILD_MODNAME
and good for that, so pass it.

Handler names will be "rt2500pci", "rt2500pci" etc.

Bluetooth: Refactor hci_dev_open to a separate hci_dev_do_open function

The requirements of an external call to hci_dev_open from hci_sock.c are
different to that from within hci_core.c. In the former case we want to
flush any pending work in hdev->req_workqueue whereas in the latter we
don't (since there we are already calling from within the workqueue
itself). This patch does the necessary refactoring to a separate
hci_dev_do_open function (analogous to hci_dev_do_close) but does not
yet introduce the synchronizations relating to the workqueue usage.

regulatory: enable channels 52-64 and 100-144 for world roaming

If allowed in a country, these channels typically require DFS

mac80211: support reporting A-MSDU subframes individually

Some devices may not be able to report A-MSDUs in
single buffers. Drivers for such devices were
forced to re-assemble A-MSDUs which would then
be eventually disassembled by mac80211. This could
lead to CPU cache thrashing and poor performance.

Since A-MSDU has a single sequence number all
subframes share it. This was in conflict with
retransmission/duplication recovery
(IEEE802.11-2012: 9.3.2.10).

Patch introduces a new flag that is meant to be
set for all individually reported A-MSDU subframes
except the last one. This ensures the
last_seq_ctrl is updated after the last subframe
is processed. If an A-MSDU is actually a duplicate
transmission all reported subframes will be
properly discarded.
