This adds a loop through the elements in the linked list, recv_msgs using
list_for_entry_safe in order to free messages in this list. In addition
we are using the safe version of this marco in order to prevent use after
bugs related to deleting the element we are on currently by holding a
pointer to the next element after the current one we are on and freeing
with the function, ipmi_free_recv_msg internally in this loop.

A new harmless warning has come up on ARM builds with gcc-4.9:
drivers/char/ipmi/ipmi_msghandler.c: In function 'smi_send.isra.11':
include/linux/spinlock.h:372:95: warning: 'flags' may be used uninitialized in this function [-Wmaybe-uninitialized]
raw_spin_unlock_irqrestore(&lock->rlock, flags);
^
drivers/char/ipmi/ipmi_msghandler.c:1490:16: note: 'flags' was declared here
unsigned long flags;
^
This could be worked around by initializing the 'flags' variable, but it
seems better to rework the code to avoid this.

The driver uses #ifdef DEBUG_TIMING in order to conditionally print out
timestamped debug messages. Unfortunately it adds the ifdefs all over the
usage sites.
This patch cleans it up by adding a debug_timestamp() function which
is compiled out if DEBUG_TIMING isn't present. This cleans up all
the ugly ifdefs in the function logic.

Removes a no longer needed FIXME comment in the function,acpi_gpe_irq_setup
for the file,ipmi_si_intf.c. This comment is no longer needed as clearly we
are passing the correct level of ACPI_GPE_LEVEL_TRIGGERED to the installer
function,acpi_install_gpe_handler due to no breakage after years of using
this ACPI level in the function,acpi_install_gpe_handler.

There can't be more than a few IPMI messages allocated at any one time,
so converting the messages to slabs would be a waste. So just remove

Pull Ceph changes from Sage Weil:
"On the RBD side, there is a conversion to blk-mq from Christoph,
several long-standing bug fixes from Ilya, and some cleanup from
Rickard Strandqvist.
On the CephFS side there is a long list of fixes from Zheng, including
improved session handling, a few IO path fixes, some dcache management
correctness fixes, and several blocking while !TASK_RUNNING fixes.
The core code gets a few cleanups and Chaitanya has added support for
TCP_NODELAY (which has been used on the server side for ages but we
somehow missed on the kernel client).
There is also an update to MAINTAINERS to fix up some email addresses
and reflect that Ilya and Zheng are doing most of the maintenance for
RBD and CephFS these days. Do not be surprised to see a pull request
come from one of them in the future if I am unavailable for some

This converts the rbd driver to use the blk-mq infrastructure. Except
for switching to a per-request work item this is almost mechanical.

him 120000 iops, although the only comparism available was an old
3.10 kernel which gave 80000iops.

If the clone is resized down to 0, it becomes standalone. If such
resize is carried over while an image is mapped we would detect this
and call rbd_dev_parent_put() which means "let go of all parent state,
including the spec(s) of parent images(s)". This leads to a mismatch
between "rbd info" and sysfs parent fields, so a fix is in order.
# rbd create --image-format 2 --size 1 foo

# rbd clone foo@snap bar

Commit a7854487cd7128a30a7f4f5259de9f67d5efb95f:
md: When RAID5 is dirty, force reconstruct-write instead of read-modify-write.
Causes an RCW cycle to be forced even when the array is degraded.
A degraded array cannot support RCW as that requires reading all data
blocks, and one may be missing.
Forcing an RCW when it is not possible causes a live-lock and the code
spins, repeatedly deciding to do something that cannot succeed.
So change the condition to only force RCW on non-degraded arrays.

to be transparently automounted on given directory in debugfs.
New primitive in there is debugfs_create_automount(name, parent, func,

open-coded in quite a few places. Dave's patch adds it and converts

Pull suspend-to-idle updates from Rafael Wysocki:
"Suspend-to-idle timer quiescing support for v3.20-rc1
Until now suspend-to-idle has not been able to save much more energy
than runtime PM because of timer interrupts that periodically bring
CPUs out of idle while they are waiting for a wakeup interrupt. Of
course, the timer interrupts are not wakeup ones, so the handling of
them can be deferred until a real wakeup interrupt happens, but at the
same time we don't want to mass-expire timers at that point.
The solution is to suspend the entire timekeeping when the last CPU is
entering an idle state and resume it when the first CPU goes out of
idle. That has to be done with care, though, so as to avoid accessing
suspended clocksources etc. end we need extra support from idle
drivers for that.
This series of commits adds support for quiescing timers during
suspend-to-idle and adds the requisite callbacks to intel_idle and the
ACPI cpuidle driver"

The dw_wdt_set_top() function takes in a value in seconds. In
dw_wdt_open() we were calling it with a value that's supposed to
represent the maximum value programmed into the "top" register with a
comment saying that we were trying to set the watchdog to its maximum
value. Instead we ended up setting the watchdog to ~15 seconds.
Let's fix this. However, setting things to the "max" gives me an 86
second watchdog in the system I'm looking at. 86 seconds feels a
little too long. We'll explicitly choose 30 seconds as a more
reasonable value.
NOTE: Ideally this driver should be transitioned to be a real watchdog
driver. Then we could use "watchdog_init_timeout" and let the timeout
be specified in a number of ways (device tree, module parameter, etc).
This patch should be considered a bit of a stopgap solution.

On some dw_wdt implementations the "top" register may be initted to 0
at bootup. In such a case, each "pat" of the watchdog will reset the
timer to 0xffff. That's pretty short.
The input clock of the wdt can be any of a wide range of values. On
an rk3288 system, I've seen the wdt clock be 24.75 MHz. That means
each tick is ~40ns and we'll count to 0xffff in ~2.6ms.
Because of the above two facts, it's a really good idea to pat the
watchdog after initting the "top" register properly and before
enabling the watchdog. If you don't then there's no way we'll get the
next heartbeat in time.
Jisheng Zhang fixed this problem on some dw_wdt versions by using the
TOP_INIT feature. However, the dw_wdt on rk3288 doesn't have TOP_INIT
so it's a good idea to also pat the watchdog manually.

On some chips, like the TPS386000, the trigger cannot be disabled
and the CPU must keep toggling the line at all times. Add a switch
"always_running" to keep toggling the GPIO line regardless of the
state of the soft part of the watchdog. The "armed" member keeps
track of whether a timeout must also cause a reset.

As more-suitable restart handlers may exist, the priority of the

the BSP by Hisashi Nakamura <hisashi.nakamura.ak@renesas.com>.
