205ee1187a libceph: follow redirect replies from osds
Follow redirect replies from osds, for details see ceph.git commit
fbbe3ad1220799b7bb00ea30fce581c5eadaf034.

v1 (current) version of redirect reply consists of oloc and oid, which
expands to pool, key, nspace, hash and oid.  However, server-side code
that would populate anything other than pool doesn't exist yet, and
hence this commit adds support for pool redirects only.  To make sure
that future server-side updates don't break us, we decode all fields
and, if any of key, nspace, hash or oid have a non-default value, error
out with "corrupt osd_op_reply ..." message.

22116525ba libceph: start using oloc abstraction
Instead of relying on pool fields in ceph_file_layout (for mapping) and
ceph_pg (for enconding), start using ceph_object_locator (oloc)
abstraction.  Note that userspace oloc currently consists of pool, key,
nspace and hash fields, while this one contains only a pool.  This is
OK, because at this point we only send (i.e. encode) olocs and never
have to receive (i.e. decode) them.

This makes keeping a copy of ceph_file_layout in every osd request
unnecessary, so ceph_osd_request::r_file_layout field is nuked.

d529ef83c3 NFS: fix the handling of NFS_INO_INVALID_DATA flag in nfs_revalidate_mapping
There is a possible race in how the nfs_invalidate_mapping function is
handled.  Currently, we go and invalidate the pages in the file and then
clear NFS_INO_INVALID_DATA.

The problem is that it's possible for a stale page to creep into the
mapping after the page was invalidated (i.e., via readahead). If another
writer comes along and sets the flag after that happens but before
invalidate_inode_pages2 returns then we could clear the flag
without the cache having been properly invalidated.

So, we must clear the flag first and then invalidate the pages. Doing
this however, opens another race:

It's possible to have two concurrent read() calls that end up in
nfs_revalidate_mapping at the same time. The first one clears the
NFS_INO_INVALID_DATA flag and then goes to call nfs_invalidate_mapping.

Just before calling that though, the other task races in, checks the
flag and finds it cleared. At that point, it trusts that the mapping is
good and gets the lock on the page, allowing the read() to be satisfied
from the cache even though the data is no longer valid.

These effects are easily manifested by running diotest3 from the LTP
test suite on NFS. That program does a series of DIO writes and buffered
reads. The operations are serialized and page-aligned but the existing
code fails the test since it occasionally allows a read to come out of
the cache incorrectly. While mixing direct and buffered I/O isn't
recommended, I believe it's possible to hit this in other ways that just
use buffered I/O, though that situation is much harder to reproduce.

The problem is that the checking/clearing of that flag and the
invalidation of the mapping really need to be atomic. Fix this by
serializing concurrent invalidations with a bitlock.

At the same time, we also need to allow other places that check
NFS_INO_INVALID_DATA to check whether we might be in the middle of
invalidating the file, so fix up a couple of places that do that
to look for the new NFS_INO_INVALIDATING flag.

Doing this requires us to be careful not to set the bitlock
unnecessarily, so this code only does that if it believes it will
be doing an invalidation.

Commit 9807362bfe1748d9bb48eecb9261f1b1aaafea1c
  "clk: si5351: declare all device IDs for module loading"
removed the common i2c_device_id and introduced new ones for each variant
of the clock generator. Instead of exploiting that information in the driver,
it still depends on platform_data passing the chips .variant.

This removes the now redundant .variant from the platform_data and puts it in
i2c_device_id's .driver_data instead.

eeb0bed557 libceph: add ceph_kv{malloc,free}() and switch to them
Encapsulate kmalloc vs vmalloc memory allocation and freeing logic into
two helpers, ceph_kvmalloc() and ceph_kvfree(), and switch to them.

ceph_kvmalloc() kmalloc()'s a maximum of 8 pages, anything bigger is
vmalloc()'ed with __GFP_HIGHMEM set.  This changes the existing
behaviour:

- for buffers (ceph_buffer_new()), from trying to kmalloc() everything
  and using vmalloc() just as a fallback

- for messages (ceph_msg_new()), from going to vmalloc() for anything
  bigger than a page

- for messages (ceph_msg_new()), from disallowing vmalloc() to use high
  memory

270750dbc1 hung_task: Display every hung task warning
When khungtaskd detects hung tasks, it prints out
backtraces from a number of those tasks.

Limiting the number of backtraces being printed
out can result in the user not seeing the information
necessary to debug the issue. The hung_task_warnings
sysctl controls this feature.

This patch makes it possible for hung_task_warnings
to accept a special value to print an unlimited
number of backtraces when khungtaskd detects hung
tasks.

The special value is -1. To use this value it is
necessary to change types from ulong to int.

a8d4b8345e introduce __fcheck_files() to fix rcu_dereference_check_fdtable(), kill rcu_my_thread_group_empty()
rcu_dereference_check_fdtable() looks very wrong,

1. rcu_my_thread_group_empty() was added by 844b9a8707f1 "vfs: fix
   RCU-lockdep false positive due to /proc" but it doesn't really
   fix the problem. A CLONE_THREAD (without CLONE_FILES) task can
   hit the same race with get_files_struct().

   And otoh rcu_my_thread_group_empty() can suppress the correct
   warning if the caller is the CLONE_FILES (without CLONE_THREAD)
   task.

2. files->count == 1 check is not really right too. Even if this
   files_struct is not shared it is not safe to access it lockless
   unless the caller is the owner.

   Otoh, this check is sub-optimal. files->count == 0 always means
   it is safe to use it lockless even if files != current->files,
   but put_files_struct() has to take rcu_read_lock(). See the next
   patch.

This patch removes the buggy checks and turns fcheck_files() into
__fcheck_files() which uses rcu_dereference_raw(), the "unshared"
callers, fget_light() and fget_raw_light(), can use it to avoid
the warning from RCU-lockdep.

fcheck_files() is trivially reimplemented as rcu_lockdep_assert()
plus __fcheck_files().

Bisection between 3.11 and 3.12 fingered commit 9824cf97 ("mm:

The counters are undeniably useful but how often do we really
need to debug TLB flush related issues?  It does not justify
taking the penalty everywhere so make it a debugging option.

Pull thermal management updates from Zhang Rui:
 "This time, the biggest change is the work of representing hardware
  thermal properties in device tree infrastructure.

  This work includes the introduction of a device tree bindings for
  describing the hardware thermal behavior and limits, and also a parser
  to read and interpret the data, and build thermal zones and thermal
  binding parameters.  It also contains three examples on how to use the
  new representation on sensor devices, using three different drivers to
  accomplish it.  One driver is in thermal subsystem, the TI SoC
  thermal, and the other two drivers are in hwmon subsystem.

  Actually, this would be the first step of the complete work because we
  still need to check other potential drivers to be converted and then
  validate the proposed API.  But the reason why I include it in this
  pull request is that, first, this change does not hurt any others
  without using this approach, second, the principle and concept of this
  change would not break after converting the remaining drivers.  BTW,
  as you can see, there are several points in this change that do not
  belong to thermal subsystem.  Because it has been suggested by Guenter
  R that in such cases, it is recommended to send the complete series
  via one single subsystem.

  Specifics:

   - representing hardware thermal properties in device tree
     infrastructure

   - fix a regression that the imx thermal driver breaks system suspend.

   - introduce ACPI INT3403 thermal driver to retrieve temperature data
     from the INT3403 ACPI device object present on some systems.

   - introduce debug statement for thermal core and step_wise governor.

   - assorted fixes and cleanups for thermal core, cpu cooling, exynos
     thrmal, intel powerclamp and imx thermal driver"

- ACPI core changes to make it create a struct acpi_device object for every

    of the current status of that device.  In accordance with this, ACPI hotplug
    operations will not delete those objects, unless the underlying ACPI tables
    go away.
 
  - On top of the above, new sysfs attribute for ACPI device objects allowing
    user space to check device status by triggering the execution of _STA for
    its ACPI object.  From Srinivas Pandruvada.
 
  - ACPI core hotplug changes reducing code duplication, integrating the
    PCI root hotplug with the core and reworking container hotplug.
 
  - ACPI core simplifications making it use ACPI_COMPANION() in the code
    "glueing" ACPI device objects to "physical" devices.
 
  - ACPICA update to upstream version 20131218.  This adds support for the
    DBG2 and PCCT tables to ACPICA, fixes some bugs and improves debug
    facilities.  From Bob Moore, Lv Zheng and Betty Dall.
 
  - Init code change to carry out the early ACPI initialization earlier.
    That should allow us to use ACPI during the timekeeping initialization
    and possibly to simplify the EFI initialization too.  From Chun-Yi Lee.
 
  - Clenups of the inclusions of ACPI headers in many places all over from

Merge tag 'pm+acpi-3.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull ACPI and power management updates from Rafael Wysocki:
 "As far as the number of commits goes, the top spot belongs to ACPI
  this time with cpufreq in the second position and a handful of PM
  core, PNP and cpuidle updates.  They are fixes and cleanups mostly, as
  usual, with a couple of new features in the mix.

  The most visible change is probably that we will create struct
  acpi_device objects (visible in sysfs) for all devices represented in
  the ACPI tables regardless of their status and there will be a new
  sysfs attribute under those objects allowing user space to check that
  status via _STA.

  Consequently, ACPI device eject or generally hot-removal will not
  delete those objects, unless the table containing the corresponding
  namespace nodes is unloaded, which is extremely rare.  Also ACPI
  container hotplug will be handled quite a bit differently and cpufreq
  will support CPU boost ("turbo") generically and not only in the
  acpi-cpufreq driver.

  Specifics:

   - ACPI core changes to make it create a struct acpi_device object for
     every device represented in the ACPI tables during all namespace
     scans regardless of the current status of that device.  In
     accordance with this, ACPI hotplug operations will not delete those
     objects, unless the underlying ACPI tables go away.
