This patch creates two functions ieee80211_wx_set_auth and
ieee80211_wx_get_auth that can be used by drivers for the wireless
extension handlers instead of writing their own, if the implementation
should be software only.
These patches enable using bcm43xx devices with WPA and this seems (as
far as I can tell) to be the only difference between the stock ieee80211
and softmac's ieee80211 left.

Most low level drivers share supported reset/classify actions and
sequence. This patch implements ata_drive_probe_reset() which helps
constructing ->probe_reset from three component operations -
softreset, hardreset and postreset. This minimizes duplicate code and
yet allows flexibility if needed. The three component operations can
also be shared by EH later.

Add new ->probe_reset operation to ata_port_operations obsoleting
->phy_reset. The main difference from ->phy_reset is that the new
operation is not allowed to manipulate libata internals directly.
It's not allowed to configure or disable the port or devices. It can
only succeed or fail and classify attached devices into passed
@classes.
This change gives more control to higher level and eases sharing reset
methods with EH.

qc used to be freed automatically on command completion. However, as
a qc can carry information about its completion status, it can be
useful to its owner/issuer after command completion. This patch makes
freeing qc responsibility of its owner. This simplifies
ata_exec_internal() and makes command turn-around for atapi request
sensing less hackish.

On SN2, MMIO writes which are issued from separate processors are not
guaranteed to arrive in any particular order at the IO hardware. When
performing such writes from the kernel this is not a problem, as a
kernel thread will not migrate to another CPU during execution, and
mmiowb() calls can guarantee write ordering when control of the IO
resource is allowed to move between threads.
However, when MMIO writes can be performed from user space (e.g. DRM)
there are no such guarantees and mechanisms, as the process may
context-switch at any time, and may migrate to a different CPU as part
of the switch. For such programs/hardware to operate correctly, it is
required that the MMIO writes from the old CPU be accepted by the IO
hardware before subsequent writes from the new CPU can be issued.
The following patch implements this behavior on SN2 by waiting for a
Shub register to indicate that these writes have been accepted. This
is placed in the context switch-in path, and only performs the wait
when the newly scheduled task changes CPUs.

When the scsi_execute_async interface was added it ended up reducing
the flexibility of userspace to send arbitrary scsi commands through
sg using SG_IO. The SG_IO interface allows userspace to specify the
CDB length. This is now ignored in scsi_execute_async and it is
guessed using the COMMAND_SIZE macro, which is not always correct,
particularly for vendor specific commands. This patch adds a cmd_len
parameter to the scsi_execute_async interface to allow the caller
to specify the length of the CDB.

Same reasoning as commit 747c8a5594
but this time we're making uart_port flags a bitwise type - not
