2779db8d37 genirq: Fix can_request_irq() for IRQs without an action
Commit 02725e7471 ('genirq: Use irq_get/put functions'),
inadvertently changed can_request_irq() to return 0 for IRQs that have
no action.  This causes pcibios_lookup_irq() to select only IRQs that
already have an action with IRQF_SHARED set, or to fail if there are
none.  Change can_request_irq() to return 1 for IRQs that have no
action (if the first two conditions are met).

9b5c7a5a97 ACPI / PM: Fix possible NULL pointer deref in acpi_pm_device_sleep_state()
After commit fa1675b (ACPI / PM: Rework and clean up
acpi_dev_pm_get_state()) a NULL pointer dereference will take place
if NULL is passed to acpi_pm_device_sleep_state() as the second
argument.

Fix that by avoiding to use the pointer that may be NULL until
it's necessary to store a return value at the location pointed to
by it (if not NULL).

0c055b3413 ALSA: hda - Fix the max length of control name in generic parser
add_control_with_pfx() in hda_generic.c assumes a shorter name string
for the control element, and this resulted in the truncation of the
long but valid string like "Headphone Surround Switch" in the middle.

This patch aligns the max size to the actual limit of snd_ctl_elem_id,
44.

9cbce8d7e1dae0744ca4f68d62aa7de18196b6f4, "console/font: Refactor font

Hence move the fonts and their support logic from drivers/video/console/ to
its own library directory lib/fonts/.
This also allows to limit processing of drivers/video/console/Makefile to
CONFIG_VT=y again.

50285882fd cifs: fix SMB2 signing enablement in cifs_enable_signing
Commit 9ddec56131 (cifs: move handling of signed connections into
separate function) broke signing on SMB2/3 connections. While the code
to enable signing on the connections was very similar between the two,
the bits that get set in the sec_mode are different.

Declare a couple of new smb_version_values fields and set them
appropriately for SMB1 and SMB2/3. Then change cifs_enable_signing to
use those instead.

0ce6cba357 cgroup: CGRP_ROOT_SUBSYS_BOUND should be ignored when comparing mount options
1672d04070 ("cgroup: fix cgroupfs_root early destruction path")
introduced CGRP_ROOT_SUBSYS_BOUND which is used to mark completion of
subsys binding on a new root; however, this broke remounts.
cgroup_remount() doesn't allow changing root options via remount and
CGRP_ROOT_SUBSYS_BOUND, which is set on all fully initialized roots,
makes the function reject all remounts.

Fix it by putting the options part in the lower 16 bits of root->flags
and masking the comparions.  While at it, make cgroup_remount() emit
an error message explaining why it's rejecting a remount request, so
that it's less of a mystery.

1abd601864 powerpc/eeh: Add eeh_dev to the cache during boot
commit f8f7d63fd9 ("powerpc/eeh: Trace eeh
device from I/O cache") broke EEH on pseries for devices that were
present during boot and have not been hotplugged/DLPARed.

eeh_check_failure will get the eeh_dev from the cache, and will get
NULL. eeh_addr_cache_build adds the addresses to the cache, but eeh_dev
for the giving pci_device is not set yet. Just reordering the call to
eeh_addr_cache_insert_dev works fine. The ordering is similar to the one
in eeh_add_device_late.

8c3d913888 MSM clock updates for 3.11.
Per Stephen Boyd's coverletter:
 
 Resending to collect higher level maintainer acks per Olof's request.
 The plan is to push this patchset through MSM to the arm-soc tree.
 
 This patchset moves the existing MSM clock code and affected drivers
 to the common clock framework. A prerequisite of moving to the common
 clock framework is to use clk_prepare() and clk_enable() so the first
 few patches migrate drivers to that call (clk_prepare() is a no-op on
 MSM right now). It also removes some custom clock APIs that MSM
 provides and finally moves the proc_comm clock code to the common
 struct clk.
 
 This patch series will be used as the foundation of the MSM 8660/8960
 clock code that I plan to send out after this series.

9dceefe483 PM / Sleep: Warn about system time after resume with pm_trace
pm_trace uses the system's Real Time Clock (RTC) to save the magic
number.  The reason for this is that the RTC is the only reliably
available piece of hardware during resume operations where a value
can be set that will survive a reboot.

Consequence is that after a resume (even if it is successful) your
system clock will have a value corresponding to the magic number
instead of the correct date/time!  It is therefore advisable to use
a program like ntp-date or rdate to reset the correct date/time from
an external time source when using this trace option.

There is no run-time message to warn users of the consequences of
enabling pm_trace.  Adding a warning message to pm_trace_store()
will serve as a reminder to users to set the system date and time
after resume.

b7f33917bc ALSA: usb-audio: add quirks for Roland QUAD/OCTO-CAPTURE
The Roland Quad/Octo-Capture devices use some unknown vendor-specific
mechanism to switch sample rates (and to manage other controls).  To
prevent the driver from attempting to use any other than the default
44.1 kHz sample rate, use quirks to hide the other alternate settings.

b1ce7ba619 ALSA: usb-audio: claim autodetected PCM interfaces all at once
snd_card_register() registers all devices newly added since the last
call.  However, the playback/capture streams are handled as one ALSA
device, so the second /dev device will not be registered if the PCM
streams are added in two steps.

QUIRK_AUTODETECT caused the probe callback to be called once for each
interface, which triggered this problem.  Work around this by handling
this like the composite quirk, i.e., autodetecting all other interfaces
that might be used for PCM or MIDI.

to let the driver detect this.
