This patch fixes the iwlwifi rfkill. It removes the input device from iwl3945,
adds support for RFKILL_STATE_HARD_BLOCKED and calls rfkill_force_state() to
update the state rather than accessing it directly.
The calls to iwl|iwl3945_rfkill_set_hw_state() had to be moved because
rfkill_force_state() cannot be called from an atomic context.
Tested on iwl3945 and seems to work fine.

Especially in the case of duplicate packets this is interesting

This fixes a circular locking dependency in the workqueue handling.
The interface work task uses the mac80211 function
ieee80211_iterate_active_interfaces() which grabs the RTNL lock.
However when the interface is brough down, this happens under the RTNL
lock as well, this causes problems because mac80211 will flush the workqueue
during the ifdown event. This causes mac80211 to wait until the driver has
completed all work which can't finish because it is waiting on the RTNL lock.
This is fixed by moving rt2x00 workqueue tasks on a different workqueue,
this workqueue can be flushed when the ieee80211_hw structure is removed
by the driver (when the driver is unloaded) which does not happen under the
RTNL lock.

When rt2x00queue_alloc_rxskbs() fails rt2x00queue_unitialize()
will be called which will free all rxskb. So we don't need
to do this in the rt2x00queue_alloc_rxskb() function as well.
rt2x00queue_free_skb() unmaps the DMA but doesn't clear the
allocation flag. Since the code is copied from rt2x00queue_unmap_skb()
anyway (and that function does clear the flag) we might as well

This introduces an almost complete SSB-DMA-API that maps to the lowlevel
bus-API based on the bustype.

We don't need these two dump-files anymore, as we can easily do this
in userspace now.
Use b43-fwdump from the b43-tools repository to dump microcode registers.
Use "b43-fwdump -s" to dump SHM (or use -S to do a binary dump)

This adds an atomic mask/set capability to the debugfs MMIO interface.
This is needed to support mask and/or set operations from the userspace
debugging tools.

Without the preallocated DMA we can now safely increase

requirements of rt2x00.

Sparse produces warnings about nested contain_of() statements,
this means that lines like:
interface_to_usbdev(to_usb_interface(rt2x00dev->dev));
will upset sparse.
Add a new macro to rt2x00usb.h which will convert to device
structure to the usb_device pointer in 2 steps to prevent this
sparse warning.

With a bit of code moving to rt2x00lib within the
TX and RX paths we can now remove a lot of EXPORT_SYMBOL_GPL()
statements. This cleans up the interface between rt2x00lib
and the drivers and has the additional benefit that rt2x00pci
and rt2x00usb are trimmed down in size as well since they
have less to do.

The current PCI drivers require a lot of pre-allocated DMA buffers. Reduce this
by using dynamically mapped skb's (using pci_map_single) instead of the pre-
allocated DMA buffers that are allocated at device start-up time.
At the same time move common RX path code into rt2x00lib from rt2x00pci and
rt2x00usb, as the RX paths now are now almost the same.

In preparation of replacing the statically allocated DMA buffers with
dynamically mapped skbs, centralize the allocation of RX skbs to rt2x00queue.c
and let rt2x00pci already use them.

At the same time clean up the device administration a bit, by storing a pointer
to struct device instead of a void pointer that is dependent on the type of
device. The normal PCI and USB subsystem provided macros can be used to convert
the device pointer to the right type.
This makes the rt2x00 driver a bit more type-safe.

The latest trace about usage of this driver I found was an (unanswered)
request for help by a user trying to get it working reliably five years
ago with kernel 2.4 .
And even if it was still working the use cases of this driver (requiring
both the hardware and someone providing this kind of wireless network)
have become practically nonexisting.
This patch therefore removes the strip driver.
