This patch allows users to override both host and device side cable detection
with "ideX=ata66" kernel parameter. Thanks to this it should be now possible
to use UDMA > 2 modes on systems (laptops mainly) which use short 40-pin cable
instead of 80-pin one.
Next patches add automatic detection of some systems using short cables.
Changes:
* Rename hwif->udma_four to hwif->cbl and make it u8.
* Convert all existing users accordingly (use ATA_CBL_* defines while at it).
* Add ATA_CBL_PATA40_SHORT support to ide-iops.c:eighty_ninty_three().
* Use ATA_CBL_PATA40_SHORT for "ideX=ata66" kernel parameter.

the Linux scheduler is starving a number of workloads. So default
to more agressive idle-balancing. This hurts lmbench context-switching
numbers (which was the main reason we sucked at idle-balancing for
such a long time) but the lmbench numbers are fine once the system is
minimally utilized.

the SMP load-balancer uses the boot-time migration-cost estimation
code to attempt to improve the quality of balancing. The reason for
this code is that the discrete priority queues do not preserve
the order of scheduling accurately, so the load-balancer skips
tasks that were running on a CPU 'recently'.
this code is fundamental fragile: the boot-time migration cost detector
doesnt really work on systems that had large L3 caches, it caused boot
delays on large systems and the whole cache-hot concept made the
balancing code pretty undeterministic as well.
(and hey, i wrote most of it, so i can say it out loud that it sucks ;-)
under CFS the same purpose of cache affinity can be achieved without
any special cache-hot special-case: tasks are sorted in the 'timeline'
tree and the SMP balancer picks tasks from the left side of the
tree, thus the most cache-cold task is balanced automatically.

This keyboard has wireless mouse which has left, middle, right buttons and
2-dimensional scrolling wheel. Unfornetuly, this wheel reports side scrolling
events and 11 or 12 button events at the same time.
I've wrote a patch to fix this mapping. I'm not sure if this mapping is proper
for buttons, because , for example, there is no entry for "burn cd" in input.h.
The patch also supress 11 and 12 button events from mouse when you scroll the
wheel left and right. With this patch, only side scrolling events are
reported. (This mouse has only 4 buttons and 2D wheel. There is no such
buttons like 11 and 12.)

Lately there have been quite a lot of bug reports against broken devices
which require us to fix their report descriptor in the runtime, before it
is passed to the HID parser. Those devices have eaten quite an amount of
our quirks space, which isn't particularly necessary - the quirks are not
needed after the report descriptor is parsed, and they just consume bits.
Therefore this patch separates the quirks for report descriptor fixup, and
moves their handling into separate code. The quirks are then forgotten as
soon as the report descriptor has been parsed.
Module parameter 'rdesc_quirks' is introduced to be able to modify these
quirks in runtime in a similar way to 'quirks' parameter for ordinary HID
quirks.

Petalynx Maxter remote control [1] 0x18b1/0x0037 emits 0xfa and 0xfc from
consumer page (reserved in HUT 1.12) for back and more keys. It also emits
a few usages from LOGIVENDOR page, which need adding.
Also, this device has broken report descriptor - the reported maximum is too
low - it doesn't contain the range for 'back' and 'more' keys, so we need to
bump it up before the report descriptor is being parsed.
Besides all this, it also requires NOGET quirk.
This patch does so.

Microsoft SideWinder GameVoice driver is a trivial device with a few buttons
(0x09 HID usage) and an audio connector, which just forwards the audio input
into oridinary sound card present in the computer.
Despite this fact, the only interface of this device reports itself as a
Telephony/Headset type of HID device. This is apparently incorrect - the device
itself doesn't provide any audio/telephony functionality. This is achieved in
userland application which only needs to receive the button events from the HID
driver.
This patch establishes a new quirk which forces hid-input to claim a device it
will otherwise leave untouched.

The SiS966 has one additional PCI-ID 1180.
If the chipset is using this PCI-ID, the primary channel is connected to the
first PATA-port. The secondary channel is connected to SATA-ports in IDE
emulation mode. The legacy IO-ports are used.
The including of the PCI-ID into pata_sis is not sufficient, because the legacy
driver in drivers/ide is initialized before pata_sis.

Commit 52ade9b3b97fd3bea42842a056fe0786c28d0555 changed the suspend code
ordering to execute pm_ops->prepare() after the device model per-device
.suspend() calls in order to fix some ACPI-related issues. Unfortunately, it
broke the at91 platform which assumed that pm_ops->prepare() would be called
before suspending devices.
at91 used pm_ops->prepare() to get notified of the target system sleep state,
so that it could use this information while suspending devices. However, with
the current suspend code ordering pm_ops->prepare() is called too late for
this purpose. Thus, at91 needs an additional method in 'struct pm_ops' that
will be used for notifying the platform of the target system sleep state.
Moreover, in the future such a method will also be needed by ACPI.
This patch adds the .set_target() method to 'struct pm_ops' and makes the
suspend code call it, if implemented, before executing the device model
per-device .suspend() calls. It also modifies the at91 code to use
pm_ops->set_target() instead of pm_ops->prepare().

Many laptops have rf-kill physical switches that are not keys, but slider
or rocker switches. Often (like in all ThinkPads with a radio kill slider
switch), they have both a slider/rocker switch and a hot key.
Trying to kludge a real switch to act like a key is not a very smart thing
to do if you can help it, and it gets specially bad when you are going to
have both in the same machine. So, we do the right thing and add an input
EV_SW event for radio kill switches.
The EV_SW SW_RADIO event is defined with positive logic, i.e. when the
switch is active, the radios are to be enabled. When the switch is
inactive, the radios are to be disabled.

Not all the world is an i386. Many architectures need 64-bit arguments to be
aligned in suitable pairs of registers, and the original
sys_sync_file_range(int, loff_t, loff_t, int) was therefore wasting an
argument register for padding after the first integer. Since we don't
normally have more than 6 arguments for system calls, that left no room for
the final argument on some architectures.
Fix this by introducing sys_sync_file_range2(int, int, loff_t, loff_t) which
all fits nicely. In fact, ARM already had that, but called it
sys_arm_sync_file_range. Move it to fs/sync.c and rename it, then implement
the needed compatibility routine. And stop the missing syscall check from
bitching about the absence of sys_sync_file_range() if we've implemented
sys_sync_file_range2() instead.
Tested on PPC32 and with 32-bit and 64-bit userspace on PPC64.

The infamous abnormal status message triggers on not so abnormal cases
including empty port and even when it's being triggered on actual
errors the info it provides is redundant and out of context - higher
level functions will print the info in better safe later anyway.
Also, by being triggered all the time, it leads people to think that
the abnormality is somehow related to all ATA and system problems
they're experiencing and gives owners of healthy systems unfounded
doubts about the integrity of the universe. Make it a DPRINTK and
