The Sony PS3 Blue-ray Disc Remote Control used to be supported by the
BlueZ project's user space, but the code that handled it was recently
removed as its functionality conflicted with a real HSP implementation
and the mapping was thought to be better handled in the kernel. This is
a port of the mapping logic from the fakehid driver by Marcel Holtmann
to the in-kernel HID layer.

We also add support for the Logitech Harmony Adapter for PS3, which
emulates the BD Remote.

The dev_rdesc member of the hid_device structure is meant to store the original
report descriptor received from the device, but it is currently passed to any
report_fixup method before it is copied to the rdesc member. This patch uses a
temporary buffer to shield dev_rdesc from the side effects of many HID drivers'
report_fixup implementations.

usbhid's hid_post_reset checks the report descriptor currently returned by the
device against a descriptor that may have been modified by a driver's
report_fixup method. That leaves some devices nonfunctional after a resume, with
a "reset_resume error 1" reported. This patch checks the new descriptor against
the unmodified dev_rdesc instead and uses the original, instead of modified,
report size.

The lg4ff driver doesn't fill the "input_absinfo" struct so it is left
with default values. Applications with rely on information in this struct
therefore do not work correctly with the wheel.

Range limiting command for the Driving Force Pro wheel is only a FF_SPRING
effect so that the wheel creates resistance when the user tries to turn it past
the limit. It is however possible to overpower the FFB motors quite easily which
leads to the X axis value exceeding the expected limit. This confuses
games which dynamically adjust calibration using the highest/lowest min and max
values reported by the wheel. Joydev device driver also doesn't take in account
any changes in an axis range after the joystick device is created.

This patch recalculates received ABS_X axis value so it is always in
<0; 16383> range where 0 is the left limit and 16383 the right limit.
Logitech driver for Windows does the same thing.  As for any concerns about
possible loss of precision, I compared a large set of raw/adjusted values
generated by "mult_frac" to values returned by the Windows driver and I got
a 100% match.

Other Logitech wheels will probably need a similar fix, but I currently lack
the information needed to write one.

This patch fixes an issue introduced after commit 4ea54542
("HID: Fix race condition between driver core and ll-driver").

After that commit, hid-core discards any incoming packet that arrives while
hid driver's probe function is being executed.

This broke the enumeration process of hid-logitech-dj, that must receive
control packets in-band with the mouse and keyboard packets. Discarding mouse
or keyboard data at the very begining is usually fine, but it is not the case
for control packets.

This patch forces a re-enumeration of the paired devices when a packet arrives
that comes from an unknown device.

Based on a patch originally written by Benjamin Tissoires.

Pull networking updates from David Miller:
 "More bug fixes, nothing gets past these guys"

 1) More kernel info leaks found by Mathias Krause, this time in the
    IPSEC configuration layers.

 2) When IPSEC policies change, we do not properly make sure that cached
    routes (which could now be stale) throughout the system will be
    revalidated.  Fix this by generalizing the generation count
    invalidation scheme used by ipv4.  From Nicolas Dichtel.

 3) When repairing TCP sockets, we need to allow to restore not just the
    send window scale, but the receive one too.  Extend the existing
    interface to achieve this in a backwards compatible way.  From
    Andrey Vagin.

 4) A fix for FCOE scatter gather feature validation erroneously caused
    scatter gather to be disabled for things like AOE too.  From Ed L
    Cashin.

 5) Several cases of mishandling of error pointers, from Mathias Krause,
    Wei Yongjun, and Devendra Naga.

 6) Fix gianfar build, from Richard Cochran.

 7) CAP_NET_* failures should return -EPERM not -EACCES, from Zhao
    Hongjiang.

 8) Hardware reset fix in janz-ican3 CAN driver, from Ira W Snyder.

 9) Fix oops during rmmod in ti_hecc CAN driver, from Marc Kleine-Budde.

10) The removal of the conditional compilation of the clk support code
    in the stmmac driver broke things.  This is because the interfaces
    used are the ones that don't also perform the enable/disable of the
    clk.  Fix from Stefan Roese.

11) The QFQ packet scheduler can record out of range virtual start
    times, resulting later in misbehavior and even crashes.  Fix from
    Paolo Valente.

12) If MSG_WAITALL is used with IOAT DMA under TCP, we can wedge the
    receiver when the advertised receive window goes to zero.  Detect
    this case and force the processing of the IOAT DMA queue when it
    happens to avoid getting stuck.  Fix from Michal Kubecek.

13) batman-adv assumes that test_bit() returns only 0 or 1, but this is
    not true for x86 (which returns -1 or 0, via the 'sbb' instruction).
    Fix from Linus Lussing.

14) Fix small packet corruption in e1000, from Tushar Dave.

15) make_blackhole() in the IPSEC policy code can do one read unlock too
    many, fix from Li RongQing.

16) The new tcp_try_coalesce() code introduced a bug in TCP URG
    handling, fix from Eric Dumazet.

17) Fix memory leak in __netif_receive_skb() when doing zerocopy and
    when hit an OOM condition.  From Michael S Tsirkin.

18) netxen blindly deferences pdev->bus->self, which is not guarenteed
    to be non-NULL.  Fix from Nikolay Aleksandrov.

clk_{un}prepare is mandatory for platforms using common clock framework.

the clocks are not correctly en-/disabled and ethernet support doesn't

The format_array_alloc() function is fundamentally racy, in that it
prints the array twice: once to figure out how much space to allocate
for the buffer, and the second time to actually print out the data.

If any of the array contents changes in between, the allocation size may
be wrong, and the end result may be truncated in odd ways.

Just don't do it.  Allocate a maximum-sized array up-front, and just
format the array contents once.  The only user of the u32_array
interfaces is the Xen spinlock statistics code, and it has 31 entries in
the arrays, so the maximum size really isn't that big, and the end
result is much simpler code without the bug.
