a5b90ef7a1 staging: dgnc: clean up the dgnc_get_modem_info()
the "ch" in dgnc_get_modem_info() was already checked before calling
this function and also if "ch" is not NULL, dgnc_get_mstat() returns
valid value so it doesn't need to check an error.

32c8deb8b6 staging: lustre: o2iblnd: per NI map-on-demand value
Enables support of different map-on-demand values per NI.  This is
required to support OPA coexistence with MLX5 cards.  MLX5 does not
support FMR, which is enabled via map-on-demand.  However OPA's
performance is greatly enahanced when FMR is enabled.  In order
to enable coexistence of both of these two types of cards we
need to be able to set different map-on-demand values for both NIs.

This patch also lays the ground work for other per NI tunables to
be added in future patches.

221446263e staging: lustre: fid: packing ost_idx in IDIF
For a normal FID, we can know on which target the related object
is allocated via querying FLDB; but it is not true for an IDIF.

To locate the OST via the given IDIF, when the IDIF is generated,
we pack the OST index in it. Then for any given FID, in spite of
t is a normal FID or not, we has the method to know which target
it belongs to. That is useful for LFSCK.

For old IDIF, the OST index is not part of the IDIF, means that
ifferent OSTs may have the same IDIFs, that may cause the IFID
in LMA does not match the read FID. Under such case, we need to
make some compatible check to avoid to trigger unexpected.

tgt_validate_obdo() converts the ostid contained in the RPC body
to fid and changes the "struct ost_id" union, then the users can
access ost_id::oi_fid directly without call ostid_to_fid() again.

It also contains some other fixing and cleanup.

Pull power management and ACPI fixes from Rafael Wysocki:
 "Fixes for problems introduced or discovered recently (intel_pstate,
  sti-cpufreq, ARM64 cpuidle, Operating Performance Points framework,
  generic device properties framework) and one fix for a hotplug-related
  deadlock in ACPICA that's been there forever, but is nasty enough.

  Specifics:

   - Fix for a recent regression in the intel_pstate driver causing it
     to fail to restore the HWP (HW-managed P-states) configuration of
     the boot CPU after suspend-to-RAM (Rafael Wysocki).

   - Fix for two recent regressions in the intel_pstate driver, one that
     can trigger a divide by zero if the driver is accessed via sysfs
     before it manages to take the first sample and one causing it to
     fail to update a structure field used in a trace point, so the
     information coming from it is less useful (Rafael Wysocki).

   - Fix for a problem in the sti-cpufreq driver introduced during the
     4.5 cycle that causes it to break CPU PM in multi-platform kernels
     by registering cpufreq-dt (which subsequently doesn't work)
     unconditionally and preventing the driver that would actually work
     from registering (Sudeep Holla).

   - Stable-candidate fix for an ARM64 cpuidle issue causing idle state
     usage counters to be incorrectly updated for idle states that were
     not entered due to errors (James Morse).

   - Fix for a recently introduced issue in the OPP (Operating
     Performance Points) framework causing it to print bogus error
     messages for missing optional regulators (Viresh Kumar).

   - Fix for a recently introduced issue in the generic device
     properties framework that may cause it to attempt to dereferece and
     invalid pointer in some cases (Heikki Krogerus).

   - Fix for a deadlock in the ACPICA core that may be triggered by
     device (eg Thunderbolt) hotplug (Prarit Bhargava)"

f0b22d1bb2 parisc: fix a bug when syscall number of tracee is __NR_Linux_syscalls
Do not load one entry beyond the end of the syscall table when the
syscall number of a traced process equals to __NR_Linux_syscalls.
Similar bug with regular processes was fixed by commit 3bb457af4f
("[PARISC] Fix bug when syscall nr is __NR_Linux_syscalls").

This bug was found by strace test suite.
