Currently getbmap uses xfs_bmapi_read to query the extent map, and then
fixes up various bits that are eventually reported to userspace.

This patch instead rewrites it to use xfs_iext_lookup_extent and
xfs_iext_get_extent to iteratively process the extent map.  This not
only avoids the need to allocate a map for the returned xfs_bmbt_irec
structures but also greatly simplified the code.

There are two intentional behavior changes compared to the old code:

 - the current code reports unwritten extents that don't directly border
   a written one as unwritten even when not passing the BMV_IF_PREALLOC
   option, contrary to the documentation.  The new code requires the
   BMV_IF_PREALLOC flag to report the unwrittent extent bit.
 - The new code does never merges consecutive extents, unlike the old
   code that sometimes does it based on the boundaries of the
   xfs_bmapi_read calls.  Note that the extent merging behavior was
   entirely undocumented.

  RDMA/netlink: OOPs in rdma_nl_rcv_msg() from misinterpreted flag

This reverts commit 651e28c5.

This caused a regression:
 "The specific problem is that dnsmasq refuses to start on openSUSE Leap
  42.2.  The specific cause is that and attempt to open a PF_LOCAL socket
  gets EACCES.  This means that networking doesn't function on a system
  with a 4.14-rc2 system."

Sadly, the developers involved seemed to be in denial for several weeks
about this, delaying the revert.  This has not been a good release for
the security subsystem, and this area needs to change development
practices.

rdma_nl_rcv_msg() checks to see if it should use the .dump() callback
or the .doit() callback.  The check is done with this check:

if (flags & NLM_F_DUMP) ...

The NLM_F_DUMP flag is two bits (NLM_F_ROOT | NLM_F_MATCH).

When an RDMA_NL_LS message (response) is received, the bit used for
indicating an error is the same bit as NLM_F_ROOT.

NLM_F_ROOT == (0x100) == RDMA_NL_LS_F_ERR.

ibacm sends a response with the RDMA_NL_LS_F_ERR bit set if an error
occurs in the service.  The current code then misinterprets the
NLM_F_DUMP bit and trys to call the .dump() callback.

If the .dump() callback for the specified request is not available
(which is true for the RDMA_NL_LS messages) the following Oops occurs:

The special value of 0 for device resume latency PM QoS means
"no restriction", but there are two problems with that.

First, device resume latency PM QoS requests with 0 as the
value are always put in front of requests with positive
values in the priority lists used internally by the PM QoS
framework, causing 0 to be chosen as an effective constraint
value.  However, that 0 is then interpreted as "no restriction"
effectively overriding the other requests with specific
restrictions which is incorrect.

Second, the users of device resume latency PM QoS have no
way to specify that *any* resume latency at all should be
avoided, which is an artificial limitation in general.

To address these issues, modify device resume latency PM QoS to
use S32_MAX as the "no constraint" value and 0 as the "no
latency at all" one and rework its users (the cpuidle menu
governor, the genpd QoS governor and the runtime PM framework)
to follow these changes.

Also add a special "n/a" value to the corresponding user space I/F
to allow user space to indicate that it cannot accept any resume
latencies at all for the given device.

Commit 3d8f7a89 ("hwmon: (tmp102) Improve handling of initial read
delay") reduced the initial temperature read delay and made it dependent
on the chip's shutdown mode. If the chip was not in shutdown mode at probe,
the read delay no longer applies.

This ignores the fact that the chip initialization changes the temperature
sensor resolution, and that the temperature register values change when
the resolution is changed. As a result, the reported temperature is twice
as high as the real temperature until the first temperature conversion
after the configuration change is complete. This can result in unexpected
behavior and, worst case, in a system shutdown. To fix the problem,
let's just always wait for a conversion to complete before reporting
a temperature.

  platform/x86: intel_pmc_ipc: Use devm_* calls in driver probe function

Currently, update_no_reboot_bit() function implemented in this driver
uses mutex_lock() to protect its register updates. But this function is
called with in atomic context in iTCO_wdt_start() and iTCO_wdt_stop()
functions in iTCO_wdt.c driver, which in turn causes "sleeping into
atomic context" issue. This patch fixes this issue by replacing the
mutex_lock() with spin_lock() to protect the GCR read/write/update APIs.

This patch cleans up unnecessary free/alloc calls in ipc_plat_probe(),
ipc_pci_probe() and ipc_plat_get_res() functions by using devm_*
calls.

This patch also adds proper error handling for failure cases in
ipc_pci_probe() function.

Pull workqueue fix from Tejun Heo:
 "This is a fix for an old bug in workqueue. Workqueue used a mutex to
  arbitrate who gets to be the manager of a pool. When the manager role
  gets released, the mutex gets unlocked while holding the pool's
  irqsafe spinlock. This can lead to deadlocks as mutex's internal
  spinlock isn't irqsafe. This got discovered by recent fixes to mutex
  lockdep annotations.

  The fix is a bit invasive for rc6 but if anything were wrong with the
  fix it would likely have already blown up in -next, and we want the
  fix in -stable anyway"
