fa68e0025d ASoC: S3C lrsync function made to work with IRQs disabled.
s3c2412_snd_lrsync() maybe reached with IRQs disabled and if LRCLK
is dead due to improper initialization of CPU or CODEC, the system
gets stuck in the loop because jiffies may never get updated.
Implemented counter based wait mechanism for atleast the same
timeout period.

Remove unnecessary (and buggy) init sequences left for IDT92HD83*
codecs in the previous fixes.  The DACs are now dynamically connected,
thus shouldn't be set statically in init verbs.  Also, the mono_nid

926e61b7c4 pkt_sched: Fix tx queue selection in tc_modify_qdisc
After the recent mq change there is the new select_queue qdisc class
method used in tc_modify_qdisc, but it works OK only for direct child
qdiscs of mq qdisc. Grandchildren always get the first tx queue, which
would give wrong qdisc_root etc. results (e.g. for sch_htb as child of
sch_prio). This patch fixes it by using parent's dev_queue for such
grandchildren qdiscs. The select_queue method's return type is changed
BTW.

75c78500dd bonding: remap muticast addresses without using dev_close() and dev_open()
This patch fixes commit e36b9d16c6. The approach
there is to call dev_close()/dev_open() whenever the device type is changed in
order to remap the device IP multicast addresses to HW multicast addresses.
This approach suffers from 2 drawbacks:

*. It assumes tha the device is UP when calling dev_close(), or otherwise
   dev_close() has no affect. It is worth to mention that initscripts (Redhat)
   and sysconfig (Suse) doesn't act the same in this matter. 
*. dev_close() has other side affects, like deleting entries from the routing
   table, which might be unnecessary.

The fix here is to directly remap the IP multicast addresses to HW multicast
addresses for a bonding device that changes its type, and nothing else.

481a819914 can: fix NOHZ local_softirq_pending 08 warning
When using nanosleep() in an userspace application we get a ratelimit warning

NOHZ: local_softirq_pending 08

for 10 times.

The echo of CAN frames is done from process context and softirq context only.
Therefore the usage of netif_rx() was wrong (for years).

This patch replaces netif_rx() with netif_rx_ni() which has to be used from
process/softirq context. It also adds a missing comment that can_send() must
no be used from hardirq context.

12e09337fe time: Prevent 32 bit overflow with set_normalized_timespec()
set_normalized_timespec() nsec argument is of type long. The recent
timekeeping changes of ktime_get_ts() feed 

	ts->tv_nsec + tomono.tv_nsec + nsecs

to set_normalized_timespec(). On 32 bit machines that sum can be
larger than (1 << 31) and therefor result in a negative value which
screws up the result completely.

Make the nsec argument of set_normalized_timespec() s64 to fix the
problem at hand. This also prevents similar problems for future users
of set_normalized_timespec().

3661d28615 ext4: Fix include/trace/events/ext4.h to work with Systemtap
Using relative pathnames in #include statements interacts badly with
SystemTap, since the fs/ext4/*.h header files are not packaged up as
part of a distribution kernel's header files.  Since systemtap doesn't
use TP_fast_assign(), we can use a blind structure definition and then
make sure the needed header files are defined before the ext4 source
files #include the trace/events/ext4.h header file.

2195d2818c fix undefined reference to user_shm_unlock
My 353d5c30c6 "mm: fix hugetlb bug due to
user_shm_unlock call" broke the CONFIG_SYSVIPC !CONFIG_MMU build of both
2.6.31 and 2.6.30.6: "undefined reference to `user_shm_unlock'".

gcc didn't understand my comment! so couldn't figure out to optimize
away user_shm_unlock() from the error path in the hugetlb-less case, as
it does elsewhere.  Help it to do so, in a language it understands.

5e3573db2b PCI hotplug: clean up acpi_run_hpp()
This patch cleans up acpi_run_hpp() and follows the style of acpi_run_hpx():
    - remove unnecessary METHOD_NAME__HPP #define
    - use ACPI_ALLOCATE_BUFFER rather than evaluating _HPP twice
    - validate _HPP package length (defined as 4 by the spec)
    - avoid ref to undefined data if FW provides < 4 elements
    - remove temporary nui[] array

Use the generic pci_configure_slot() rather than the PCIe-specific
program_fw_provided_values().

Unlike the previous pciehp-specific code, we now walk through subordinate
devices even if there are no settings for the parent.  This should be
harmless because we won't change anything unless we discover firmware
settings farther down.

8838400db5 PCI hotplug: add pci_configure_slot()
This patch adds a new pci_configure_slot() function that programs the
PCI bus characteristics for a newly-added device.  This is based on
code in pciehp_pci.c, but should be generic enough to be used by pciehp,
shpchp, and acpiphp.

The hotplug_params struct and the program_hpp_typeX() functions are based
on the ACPI definitions, but they aren't really ACPI-specific, and there's
no alternate implementation, so I don't see the need to abstract them yet.
