Pile of -fixes all over the place. Lot's of cc: stable.

Only big thing is that we've dropped the preliminary hw support tag for
bdw - it seems to work. Which also means that I'll shovel a few more bdw
patches through -fixes, there's 5 w/a patches from Ken already on
intel-gfx.

Boris BREZILLON a04c3f01d3 watchdog: at91sam9_wdt: avoid spurious watchdog reset during init
Use the min_heartbeat value instead of the calculated heartbeat value for
the first watchdog reset to avoid spurious watchdog reset.

Resetting the watchdog counter during init might lead to a watchdog fault
reset because the watchdog counter has to be running for at least
min_heartbeat.

Resetting the watchdog counter after heartbeat might lead to a watchdog
timeout reset because the watchdog counter is running for more than
max_heartbeat time.

Using min_heartbeat instead of heartbeat does not guarantee that the
watchdog won't trigger a reset, but at least it reduces the chances to be
in such a case.

Boris BREZILLON 5161b31dc3 watchdog: at91sam9_wdt: better watchdog support
The at91sam9 watchdog timer can only be configured once, and the current
implementation tries to configure it in a static way:
- 2 seconds timeout
- wdt restart every 500ms

If the timer has already been configured with different values, it returns an
error and do not create any watchdog device.

This is not critical if the watchdog is disabled, but if it has been enabled with
different timeout values it will lead to a SoC reset.

This patch series tries to address this issue by adapting the heartbeat value
according the WDT timer config:
- it first tries to configure the timer as requested.
- if it fails it fallbacks to the current config, adapting its heartbeat timer
to the needs

This patch series also move to a dynamically allocated at91wdt device instead
of the static instance.

It adds a new at91 wdt type: software. This new type make use of the at91 wdt
interrupt to trigger a software reboot.

Finally it adds several properties to the device tree bindings.

Doug Anderson cffc9a60eb watchdog: s3c2410_wdt: Report when the watchdog reset the system
A good watchdog driver is supposed to report when it was responsible
for resetting the system.  Implement this for the s3c2410, at least on
exynos5250 and exynos5420 where we already have a pointer to the PMU
registers to read the information.

Note that exynos4 SoCs also provide the reset status, but providing
that is left as an exercise for future changes and is not plumbed up
in this patch series.  Also note the exynos4 SoCs don't appear to need
any PMU config, which is why this patch separates the concepts of
having PMU Registers vs. needing PMU Config.

Doug Anderson 178624403c watchdog: s3c2410_wdt: Handle rounding a little better for timeout
The existing watchdog timeout worked OK but didn't deal with
rounding in an ideal way when dividing out all of its clocks.

Specifically if you had a timeout of 32 seconds and an input clock of
66666666, you'd end up setting a timeout of 31.9998 seconds and
reporting a timeout of 31 seconds.

Specifically DBG printouts showed:
  s3c2410wdt_set_heartbeat: count=16666656, timeout=32, freq=520833
  s3c2410wdt_set_heartbeat: timeout=32, divisor=255, count=16666656 (0000ff4f)
and the final timeout reported to the user was:
  ((count / divisor) * divisor) / freq
  (0xff4f * 255) / 520833 = 31 (truncated from 31.9998)
the technically "correct" value is:
  (0xff4f * 255) / (66666666.0 / 128) = 31.9998

By using "DIV_ROUND_UP" we can be a little more correct.
  s3c2410wdt_set_heartbeat: count=16666688, timeout=32, freq=520834
  s3c2410wdt_set_heartbeat: timeout=32, divisor=255, count=16666688 (0000ff50)
and the final timeout reported to the user:
  (0xff50 * 255) / 520834 = 32
the technically "correct" value is:
  (0xff50 * 255) / (66666666.0 / 128) = 32.0003

We'll use a DIV_ROUND_UP to solve this, generally erroring on the side
of reporting shorter values to the user and setting the watchdog to
slightly longer than requested:
* Round input frequency up to assume watchdog is counting faster.
* Round divisions by divisor up to give us extra time.

At the same time we can avoid a for loop by just doing the right math.

Doug Anderson 0f1dd98d89 watchdog: s3c2410_wdt: Only register for cpufreq on ARM_S3C24XX_CPUFREQ
On modern SoCs the watchdog timer is parented on a clock that doesn't
change every time we have a cpufreq change.  That means we don't need
to constantly adjust the watchdog timer, so avoid registering for and
dealing with cpufreq transitions unless we've actually got
CONFIG_ARM_S3C24XX_CPUFREQ defined.

Note that this is more than just an optimization.  The s3c2410
watchdog driver actually pats the watchdog on every CPU frequency
change.  On modern systems these happen many times per second (even in
a system where "nothing" is happening).  That effectively makes any
userspace watchdog program useless (the watchdog is constantly patted
by the kernel).  If we need ARM_S3C24XX_CPUFREQ defined on a
multiplatform kernel we'll need to make sure that kernel supports
common clock and change this to user common clock framework.

Ivan Khoronzhuk f48f3ceabf watchdog: davinci: change driver to use WDT core
To reduce code duplicate and increase code readability use WDT core
code to handle WDT interface.

Remove io_lock as the WDT core uses mutex to lock each wdt device.
Remove wdt_state as the WDT core tracks state with its own variable.

The watchdog_init_timeout() can read timeout value from timeout-sec
property if the passed value is out of bounds. The heartbeat is
initialized in next way. If heartbeat is not set thought module
parameter, try to read it's value from WDT node timeout-sec property.
If node has no one, use default value.

The heartbeat is hold in wdd->timeout by WDT core, so use it in
order to set timeout period.

Davinci WDT can't be stopped and once it's expired - it can be
rearmed only after hardware reset, that's why nowayout feature
is enforced.

o Vlan list was getting re-initialized in case of adapter reset.
o Tx queue was timing out because of missing start queue for a corresponding

Pull ceph updates from Sage Weil:
 "This is a big batch.  From Ilya we have:

   - rbd support for more than ~250 mapped devices (now uses same scheme
     that SCSI does for device major/minor numbering)
   - crush updates for new mapping behaviors (will be needed for coming
     erasure coding support, among other things)
   - preliminary support for tiered storage pools

  There is also a big series fixing a pile cephfs bugs with clustered
  MDSs from Yan Zheng, ACL support for cephfs from Guangliang Zhao, ceph
  fscache improvements from Li Wang, improved behavior when we get
  ENOSPC from Josh Durgin, some readv/writev improvements from

Doug Anderson 2c34d59916 watchdog: core: Make dt "timeout-sec" property work on drivers w/out min/max
It is valid for a watchdog driver to have 0 for a "min" and "max"
timeout if the driver doesn't need the core to enforce the concepts of
min and max.  The s3c2410_wdt driver is one such driver.  Specifically
it can be hard for that driver to come up with a static "max" on all
platforms without a lot more information since the input clock on
S3C2410 and S3C2440 can change with DVFS.

As written, watchdog_init_timeout() will not ever read "timeout-sec"
on these drivers since watchdog_timeout_invalid() will _never_ return
true.  Change to not consider a timeout_parm of 0 as valid even if
min/max aren't specified by the driver.  Also handle the case when
there is no min/max and no "timeout-sec" property.

strings, cast PAGE_CACHE_SIZE to size_t to be in line with dout()s in
ceph_page_mkwrite().
