Flash/torch LEDs are controlled by other driver using LED camera trigger
APIs, ledtrig_flash_ctrl()/ledtrig_torch_ctrl().
Then, actual device control is activated by each LED driver such like
LM355x or LM3642.

Some LED devices support flash/torch functionality through the LED subsystem.
This patch enables direct LED trigger controls by the driver.
Flash on/off and torch on/off can be done simply by other driver space.
Two trigger APIs are added, ledtrig_flash_ctrl() and ledtrig_torch_ctrl().

Macros are used in case that an inline function doesn't work.
Otherwise, use an empty inline function.

(a) Case of !CONFIG_LEDS_TRIGGERS
Following macros are replaced with inline functions.
  led_trigger_register_simple()
  led_trigger_unregister_simple()
  led_trigger_event()
To make inline types, the structure, 'led_trigger' should be defined.
This structure has no member at all.

(b) Case of !CONFIG_LEDS_TRIGGER_IDE_DISK
ledtrig_ide_activity() macro is replaced with an inline function as well.

(c) DEFINE_LED_TRIGGER() and DEFINE_LED_TRIGGER_GLOBAL()
Struct 'led_trigger' is defined both cases, with CONFIG_LEDS_TRIGGERS and
without CONFIG_LEDS_TRIGGERS.
Those macros are moved out of CONFIG_LED_TRIGGERS because of no-dependency
on CONFIG_LEDS_TRIGGERS.

(d) Fix build errors in mmc-core driver
After replacing macros with inline functions, following build errors occur.
(condition: CONFIG_LEDS_TRIGGERS is not set)

  drivers/mmc/core/core.c: In function 'mmc_request_done':
  drivers/mmc/core/core.c:164:25: error: 'struct mmc_host' has no member named 'led'
  drivers/mmc/core/core.c: In function 'mmc_start_request':
  drivers/mmc/core/core.c:254:24: error: 'struct mmc_host' has no member named 'led'
  make[3]: *** [drivers/mmc/core/core.o] Error 1

The reason of these errors is non-existent member variable, 'led'.
It is only valid when CONFIG_LEDS_TRIGGERS is set.
But now, it can be used without this dependency.
To fix build errors, member 'led' is always used without its config option in
'include/linux/mmc/host.h'.

LP5562 can drive up to 4 channels, RGB and White.
LEDs can be controlled directly via the led class control interface.

 LP55xx common driver
  LP5562 is one of LP55xx family device, so LP55xx common code are used.
  On the other hand, chip specific configuration is defined in the structure
  'lp55xx_device_config'

 LED pattern data
  LP5562 has also internal program memory which is used for running various LED
  patterns. LP5562 driver supports the firmware interface and the predefined
  pattern data as well.

 LP5562 device attributes: 'led_pattern' and 'engine_mux'
  A 'led_pattern' is an index code which runs the predefined pattern data.
  And 'engine_mux' is updated with the firmware interface is activated.
  Detailed description has been updated in the documentation files,
  'leds-lp55xx.txt' and 'leds-lp5562.txt'.

 Changes on the header file
  LP5562 configurable definitions are added.
  Pattern RGB data is fixed as constant value.
  (No side effect on other devices, LP5521 or LP5523.)

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client:
  rbd: don't zero-fill non-image object requests

A result of ENOENT from a read request for an object that's part of
an rbd image indicates that there is a hole in that portion of the
image.  Similarly, a short read for such an object indicates that
the remainder of the read should be interpreted a full read with
zeros filling out the end of the request.

This behavior is not correct for objects that are not backing rbd
image data.  Currently rbd_img_obj_request_callback() assumes it
should be done for all objects.

Change rbd_img_obj_request_callback() so it only does this zeroing
for image objects.  Encapsulate that special handling in its own
function.  Add an assertion that the image object request is a bio
request, since we assume that (and we currently don't support any
other types).

This resolves a problem identified here:
    http://tracker.ceph.com/issues/4559

This patch fixes a regression introduced in v3.8-rc1 code where a failed
target_check_reservation() check in target_setup_cmd_from_cdb() was causing
an incorrect SAM_STAT_GOOD status to be returned during a WRITE operation
performed by an unregistered / unreserved iscsi initiator port.

This regression is only effecting iscsi-target due to a special case check
for TCM_RESERVATION_CONFLICT within iscsi_target_erl1.c:iscsit_execute_cmd(),
and was still correctly disallowing WRITE commands from backend submission
for unregistered / unreserved initiator ports, while returning the incorrect
SAM_STAT_GOOD status due to the missing SAM_STAT_RESERVATION_CONFLICT
assignment.

This regression was first introduced with:

commit de103c93
Author: Christoph Hellwig <hch@lst.de>
Date:   Tue Nov 6 12:24:09 2012 -0800

    target: pass sense_reason as a return value

Go ahead and re-add the missing SAM_STAT_RESERVATION_CONFLICT assignment
during a target_check_reservation() failure, so that iscsi-target code
sends the correct SCSI status.

All other fabrics using target_submit_cmd_*() with a RESERVATION_CONFLICT
call to transport_generic_request_failure() are not effected by this bug.

This reverts commit 18693050 ("mm: introduce VM_POPULATE flag to
better deal with racy userspace programs").

VM_POPULATE only has any effect when userspace plays racy games with
vmas by trying to unmap and remap memory regions that mmap or mlock are
operating on.

Also, the only effect of VM_POPULATE when userspace plays such games is
that it avoids populating new memory regions that get remapped into the
address range that was being operated on by the original mmap or mlock
calls.

Let's remove VM_POPULATE as there isn't any strong argument to mandate a

Pull crypto fixes from Herbert Xu:
 "This removes IPsec ESN support from the talitos/caam drivers since
  they were implemented incorrectly, causing interoperability problems
  if ESN is used with them."

  Revert "crypto: caam - add IPsec ESN support"

Pull fbdev fixes from Tomi Valkeinen:
 "Since Florian is still away/inactive, I volunteered to collect fbdev
  fixes for 3.9 and changes for 3.10.  I didn't receive any other fbdev
  fixes than OMAP yet, but I didn't want to delay this further as
  there's a compilation fix for OMAP1.  So there could be still some
  fbdev fixes on the way a bit later.

  This contains:

   - Fix OMAP1 compilation
   - OMAP display fixes"

* tag 'fbdev-fixes-3.9-rc4' of git://gitorious.org/linux-omap-dss2/linux:
  omapdss: features: fix supported outputs for OMAP4
  OMAPDSS: tpo-td043 panel: fix data passing between SPI/DSS parts
  omapfb: fix broken build on OMAP1

Pull userns fixes from Eric W Biederman:
 "The bulk of the changes are fixing the worst consequences of the user
  namespace design oversight in not considering what happens when one
  namespace starts off as a clone of another namespace, as happens with
  the mount namespace.

  The rest of the changes are just plain bug fixes.

  Many thanks to Andy Lutomirski for pointing out many of these issues."

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace:
  userns: Restrict when proc and sysfs can be mounted
  ipc: Restrict mounting the mqueue filesystem
  vfs: Carefully propogate mounts across user namespaces
  vfs: Add a mount flag to lock read only bind mounts
  userns:  Don't allow creation if the user is chrooted
  yama:  Better permission check for ptraceme
  pid: Handle the exit of a multi-threaded init.
  scm: Require CAP_SYS_ADMIN over the current pidns to spoof pids.
