[jkosina@suse.cz: fix ordering]

There are some Sony clone gamepads that are incompatible
with PS3 since firmware 3.50, as they decided to prevent those
devices to work, without any good technical reason. I was one of those
'blessed' people affected by their niceness with their customers.
Marcelo also has another device with a similar problem.
Perhaps due to Sony's way to block the device, damaging the device's
eeprom, or perhaps because they just have a different, broken Report
descriptor, there are 3 buttons that don't work on both devices
(the ones equivalent to square, round and X).
What it happens is that the descriptor generate weird EV_ABS events
to those buttons, instead of EV_MSC/EV_KEY.
A fix that seems to be enough for them is to return the original
sixaxis table instead of the broken one. That's what this patch
does.
Yet, there are some missing entries at the used keytable. On my
tests, all keys are now producing the right events, but the reported
keycodes look weird:
"square" key: (Button.0010 = 1)
1355524363.460835: event type EV_MSC(0x04): scancode = 0x90010
1355524363.460835: event type EV_KEY(0x01) key_up: BTN_DEAD(0x0001)
"round" key: (Button.000e = 1)
1355524410.908705: event type EV_MSC(0x04): scancode = 0x9000e
1355524410.908705: event type EV_KEY(0x01) key_down: (0x0001)
1355524410.971788: event type EV_MSC(0x04): scancode = 0x9000e
1355524410.971788: event type EV_KEY(0x01) key_up: (0x0001)
"X" key: (Button.000f = 1)
1355524384.880813: event type EV_MSC(0x04): scancode = 0x9000f
1355524384.880813: event type EV_KEY(0x01) key_down: (0x0001)
1355524384.979815: event type EV_MSC(0x04): scancode = 0x9000f
1355524384.979815: event type EV_KEY(0x01) key_up: (0x0001)
The rationale is likely due to those entries at rdesc table, where the
Kernel were not likely able to parse:
Button.000d ---> Key.?
Button.000e ---> Key.?
Button.000f ---> Key.?
Button.0010 ---> Key.BtnDead
Button.0011 ---> Key.?
Button.0012 ---> Key.?
Button.0013 ---> Key.?
As a reference, this is the rdisc used on my clone (a Mad Catz
model 8846):

This patch against kernel 3.7.0-rc8 fixes a kernel oops when turning on the
bluetooth mouse with id 0458:0058 [1].
The mouse in question supports both input and hid sessions, however it is
blacklisted in drivers/hid/hid-core.c so the input session is one that should
be used. Long ago (around kernel 3.0.0) some changes in the bluetooth
subsystem made the kernel do not fallback to input session when hid session is
not supported or blacklisted. This patch restore that behaviour by making the
kernel try the input session if hid_add_device returns ENODEV.
The patch exports hid_ignore() from hid-core.c so that it can be used in the
bluetooth subsystem.

Win 8 device specification changed the requirements for the hid usages
of the multitouch devices. Now InRange is optional and must be only
used when the device supports hovering.
This ensures that the quirk ALWAYS_VALID is taken into account and
also ensures its precedence over the other VALID* quirks.

Win8 devices are required to present the feature "Maximum Contact Number".
Fortunately all win7 devices I've seen presents this feature.
If the current value is 0, then, the driver can get the actual supported
contact count by refering to the logical_max.
This win8 specification ensures that logical_max may not be above 250.
This also allows us to detect when devices like irtouch or stantum reports
an obviously wrong value of 255.

On a device with a logical_max of 3008 and a physical_max of 255mm,

- after rmmod/modprobe cycle of bus driver, the input is not claimed any

- it causes memory corruption on hidraw_list

Button names for USB gamepads are currently assigned incorrectly, as the evdev
code assigned to buttons is "BTN_GAMEPAD + code", which on devices with more
then 16 buttons bleeds over into button names reserved for graphic tablets
(BTN_TOOL_PEN, etc.). This causes problems further down the line as the device
are now no longer detected as joystick. This patch fixes that by assigning
buttons outside the range to BTN_TRIGGER_HAPPY (as is already the case for USB
joysticks).
Furthermore this patch corrects the assignment to BTN_TRIGGER_HAPPY, as
currently the first button over 16 is assigned to BTN_TRIGGER_HAPPY17 (i.e.
BTN_TRIGGER_HAPPY+0x10) not BTN_TRIGGER_HAPPY.

For example, moving the stick to the left will generate the "A" key being

15 00 -- global; Logical Minimum -- 0
26 ff 00 -- global; Logical Maximum -- ff

I.e. it makes us think that there are all kinds of usages of system
control. That the keyboard is a not only a keyboard, but also a
joystick, mouse, gamepad, keypad, etc. The same as for the Wireless
Desktop Receiver, this should be Physical Min/Max. So fix that
appropriately.

Pull workqueue changes from Tejun Heo:
"This is workqueue updates for v3.7-rc1. A lot of activities this
round including considerable API and behavior cleanups.
* delayed_work combines a timer and a work item. The handling of the
timer part has always been a bit clunky leading to confusing
cancelation API with weird corner-case behaviors. delayed_work is
updated to use new IRQ safe timer and cancelation now works as
expected.
* Another deficiency of delayed_work was lack of the counterpart of
mod_timer() which led to cancel+queue combinations or open-coded
timer+work usages. mod_delayed_work[_on]() are added.
These two delayed_work changes make delayed_work provide interface
and behave like timer which is executed with process context.
* A work item could be executed concurrently on multiple CPUs, which
is rather unintuitive and made flush_work() behavior confusing and
half-broken under certain circumstances. This problem doesn't
exist for non-reentrant workqueues. While non-reentrancy check
isn't free, the overhead is incurred only when a work item bounces
across different CPUs and even in simulated pathological scenario
the overhead isn't too high.
All workqueues are made non-reentrant. This removes the
distinction between flush_[delayed_]work() and
flush_[delayed_]_work_sync(). The former is now as strong as the
latter and the specified work item is guaranteed to have finished
execution of any previous queueing on return.
* In addition to the various bug fixes, Lai redid and simplified CPU
hotplug handling significantly.
* Joonsoo introduced system_highpri_wq and used it during CPU
hotplug.
There are two merge commits - one to pull in IRQ safe timer from
tip/timers/core and the other to pull in CPU hotplug fixes from
wq/for-3.6-fixes as Lai's hotplug restructuring depended on them."
Fixed a number of trivial conflicts, but the more interesting conflicts
were silent ones where the deprecated interfaces had been used by new
code in the merge window, and thus didn't cause any real data conflicts.
