Logitech devices use a vendor protocol to communicate various
information with the device. This protocol is called HID++,
and an exerpt can be found here:
https://drive.google.com/folderview?id=0BxbRzx7vEV7eWmgwazJ3NUFfQ28&usp=shar

The main difficulty which is related to this protocol is that
it is a synchronous protocol using the input reports.
So when we want to get some information from the device, we need
to wait for a matching input report.

This driver introduce this capabilities to be able to support
the multitouch mode of the Logitech Wireless Touchpad T651
(the bluetooth one). The multitouch data is available directly
from the mouse input reports, and we just need to query the device
on connect about its caracteristics.

HID++ and the touchpad features has a specific reporting mode
which uses pure HID++ reports, but Logitech told us not to use
it for this specific device. During QA, they detected that
some bluetooth input reports where lost, and so the only supported
mode is the pointer mode.

Several benefits here:
- we can drop the macro is_dj_device: I never been really conviced by
  this macro as we could fall into a null pointer anytime. Anyway time
  showed that this never happened.
- we can simplify the hid driver logitech-djdevice, and make it aware
  of any new receiver VID/PID.
- we can use the Wireless PID of the DJ device as the product id of the
  hid device, this way the sysfs will differentiate between different
  DJ devices.

This allows the transport layer (I have in mind hid-logitech-dj and uhid)
to set the group before it is added to the hid bus. This way, it can
bypass the hid_scan_report() call, and choose in advance which driver
will handle the newly created hid device.

This patch fixes a bug on hotmod removing.

After ipmi interface is removed using hotmod, kernel panic occurs when
rmmod impi_si.  For example, try this:

 # echo "remove,"`cat /proc/ipmi/0/params` > \
 /sys/module/ipmi_si/parameters/hotmod
 # rmmod ipmi_si

Then, rmmod fails with the following messages.

list_del in cleanup_one_si() fails because the smi_info is already
removed when hotmod removing.

When ipmi interface is removed by hotmod, smi_info is removed by
cleanup_one_si(), but is is still set in drvdata.  Therefore when rmmod
ipmi_si, ipmi_pnp_remove tries to remove it again and fails.

By this patch, a pointer to smi_info in drvdata is cleared when hotmod
removing so that it will be not accessed when rmmod.

Building ipmi on arm with gcc-4.9 results in this warning for an

    struct timespec busy_until;
                    ^

The warning is bogus and this case can not occur.  Apparently this is a
false positive resulting from gcc getting a little smarter about
tracking assignments but not smart enough.

Marking the ipmi_thread_busy_wait function as inline gives the gcc
optimization logic enough information to figure out for itself that the
case cannot happen, which gets rid of the warning without adding any
fake initialization.

  init/Kconfig: Hide printk log config if CONFIG_PRINTK=n

commit 03b8c7b6 ("futex: Allow
architectures to skip futex_atomic_cmpxchg_inatomic() test") added the
HAVE_FUTEX_CMPXCHG symbol right below FUTEX.  This placed it right in
the middle of the options for the EXPERT menu.  However,
HAVE_FUTEX_CMPXCHG does not depend on EXPERT or FUTEX, so Kconfig stops
placing items in the EXPERT menu, and displays the remaining several
EXPERT items (starting with EPOLL) directly in the General Setup menu.

Since both users of HAVE_FUTEX_CMPXCHG only select it "if FUTEX", make
HAVE_FUTEX_CMPXCHG itself depend on FUTEX.  With this change, the
subsequent items display as part of the EXPERT menu again; the EMBEDDED
menu now appears as the next top-level item in the General Setup menu,
which makes General Setup much shorter and more usable.

  the bug was not very reproducible, and finally came up with the commit
  that I could reproduce easily within a few minutes, and without the
  change I could run the tests over an hour without issue.  The change
  fit the bug and I figured out a fix.  That bad commit was:

    Commit 651e22f2 "ring-buffer: Always reset iterator to reader page"

  This commit fixed a bug, but in the process created another one.  It
  used the wrong value as the cached value that is used to see if things
  changed while an iterator was in use.  This made it look like a change
  always happened, and could cause the iterator to go into an infinite
  loop"
