Apparently, "while true; do cat </dev/null >/dev/input/mice; done" causes
an OOM in a short amount of time. Funny that nobody noticed, it actually
is very easy to trigger just by switching between VT1 and VT7...

This patch defines a new template to represent each type of
controllers (identified by the processor used). The template has
members that is set with appropriate values during driver
initialisation. This change is done to support new controllers with
minimal change to existing code. In future, for a new controller
support, a template will be declared and its members initialised
appropriately.

The MII registers read/write function blindly busy waits for an
amount of 1000 us (1 ms), then up to 200 ms. These functions are
called from irq disabled context. Depending on the clock management,
it triggers lost ticks events. Since the value is way above the
standard delay required for mii register access, it strangely looks
like a bandaid against posted writes.

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.

Added default handlers for various 802.11h DFS and TPC information
elements. Moved all information elements into single location (called
from two places). Added debug message with information on unparsed IEs
if debug_level set. Added code to reset network IBSS DFS information
when appropriate. Added code to invoke driver callback for 802.11h

To support IEEE 802.11h in IBSS, an ibss_dfs field is added to struct
ieee80211_network. In IBSS, if one STA sends a beacon with DFS info
(for radar detection), all the other STAs should receive and store
this DFS. All STAs should send the DFS as one of the information
element in the beacon they are scheduled to send (if possible) in
the future.
Since the ibss_dfs has variable length, it must be allocated
dynamically. ieee80211_network_reset() is added to clear the ibss_dfs
field. ieee80211_network_free() is also updated to free the ibss_dfs
field if it is not NULL.

On occasion, a user will submit a patch that enables the "mod15write"
quirk for their device. Enabling this quirk has the effect of clamping
all ATA commands to no more than 15 sectors. The intended use of this
quirk is to stop the controller from generating FIS's of unusual size
("but Wesley, what about the FOUS's?"), which in turn works around
problems in a <list> of hard drives.
One side effect of this quirk is greatly decreased performance. Users
often enable the mod15write quirk to fix various system, power, chip,
and/or driver problems. For a few rare problematic cases, enabling this
has cured lockups or data corruption.
Rather than add bogus listings to the mod15write quirk list (I get a
patch every month doing such), we add a 'slow_down' module parameter.
This allows users to employ a performance sledgehammer in the hopes
of curing a problem. It defaults to off (0), of course.
