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.

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.
The code for pulling the key to use for decrypt was correctly using

Userspace governor need not to hold it's own cpufreq_policy,
better make use of the global core policy.
Also fixes a bug in case of frequency changes via _PPC.
Old min/max values have wrongly been passed to __cpufreq_driver_target()
(kind of buffered) and when max freq was available again, only the old
max(normally lowest freq) was still active.

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.
