Viresh Kumar dde370b23c PM / OPP: Mark cpumask as const in dev_pm_opp_set_sharing_cpus()
dev_pm_opp_set_sharing_cpus() isn't supposed to update the cpumask
passed as its parameter, and so it should always have been marked
'const'.

Do it now.

Viresh Kumar d708b384c0 PM / OPP: -ENOSYS is applicable only to syscalls
Some of the routines have used -ENOSYS for the cases where the
functionality isn't implemented in the kernel. But ENOSYS is supposed to
be used only for syscalls.

Replace that with -ENOTSUPP, which specifically means that the operation
isn't supported.

While at it, replace exiting -EINVAL errors for similar cases to
-ENOTSUPP.

Viresh Kumar 46e7a4e183 PM / OPP: Mark shared-opp for non-dt case
opp core allows OPPs to be explicitly marked as shared from platform
code, in case of operating-point v1 bindings.

Though we do everything fine in that case, we don't set the flag in the
opp-table to indicate that the OPPs are shared. It works fine today as
the flag isn't used anywhere else in the core, but we should be doing
the right thing by marking it set.

Viresh Kumar 2c93104ff2 PM / OPP: Relocate dev_pm_opp_set_sharing_cpus()
Move dev_pm_opp_set_sharing_cpus() towards the end of the file. This
is required for better readability after the next patch is applied,
which adds dev_pm_opp_get_sharing_cpus().

Linus Torvalds 4dfa5739d9 asm-generic changes for 4.6-rc
Here is one patch to wire up the preadv/pwritev system calls in the
 generic system call table, which is required for all architectures
 that were merged in the last few years, including arm64.
 
 Usually these get merged along with the syscall implementation
 or one of the architecture trees, but this time that did not
 happen.

Pull IOMMU fixes from Joerg Roedel:
 "The fixes include:

   - Two patches to revert the use of default domains in the ARM SMMU
     driver.  Enabling this caused regressions which need more thorough
     fixing.  So the regressions are fixed for now by disabling the use
     of default domains.

   - A fix for a v4.4 regression in the AMD IOMMU driver which broke

Tony Luck ea5dfb5fae x86 EDAC, sb_edac.c: Take account of channel hashing when needed
Haswell and Broadwell can be configured to hash the channel
interleave function using bits [27:12] of the physical address.

On those processor models we must check to see if hashing is
enabled (bit21 of the HASWELL_HASYSDEFEATURE2 register) and
act accordingly.

In commit:

  eb1af3b71f ("Fix computation of channel address")

I switched the "sck_way" variable from holding the log2 value read
from the h/w to instead be the actual number. Unfortunately it
is needed in log2 form when used to shift the address.

 The most important is the memory leak fix in
 dwc3/debugfs.c. We also have a fix for PHY handling
 in suspend/resume and a fix for dwc3-omap's error
 handling.
 
 Suspend/resume also had the potential to trigger a
 NULL pointer dereference on dwc3; that's also fixed
 now.
 
 Our good ol' ffs function gets a use-after-free fix
 while the generic composite.c layer has a robustness
 fix by making sure reserved fields of a possible SSP
 device capability descriptor is cleared to 0.

Sebastian Andrzej Siewior 3b9d6da67e cpu/hotplug: Fix rollback during error-out in __cpu_disable()
The recent introduction of the hotplug thread which invokes the callbacks on
the plugged cpu, cased the following regression:

If takedown_cpu() fails, then we run into several issues:

 1) The rollback of the target cpu states is not invoked. That leaves the smp
    threads and the hotplug thread in disabled state.

 2) notify_online() is executed due to a missing skip_onerr flag. That causes
    that both CPU_DOWN_FAILED and CPU_ONLINE notifications are invoked which
    confuses quite some notifiers.

 3) The CPU_DOWN_FAILED notification is not invoked on the target CPU. That's
    not an issue per se, but it is inconsistent and in consequence blocks the
    patches which rely on these states being invoked on the target CPU and not
    on the controlling cpu. It also does not preserve the strict call order on
    rollback which is problematic for the ongoing state machine conversion as
    well.

To fix this we add a rollback flag to the remote callback machinery and invoke
the rollback including the CPU_DOWN_FAILED notification on the remote
cpu. Further mark the notify online state with 'skip_onerr' so we don't get a
double invokation.

This workaround will go away once we moved the unplug invocation to the target
cpu itself.

[ tglx: Massaged changelog and moved the CPU_DOWN_FAILED notifiaction to the
  	target cpu ]

  In file included from builtin-check.c:32:0:
  elf.h:22:18: fatal error: gelf.h: No such file or directory

  ...

Digging into it, it appears that the $(shell ..) command in the Makefile does
not give the proper result when it fails to find -lelf, and continues to
compile objtool.

Instead, use the "try-run" makefile macro to perform the test. This gives a
proper result for both cases.

Jérôme Glisse 054892ed6a drm/amdgpu: forbid mapping of userptr bo through radeon device file
Allowing userptr bo which are basicly a list of page from some vma
(so either anonymous page or file backed page) would lead to serious
corruption of kernel structures and counters (because we overwrite
the page->mapping field when mapping buffer).

This will already block if the buffer was populated before anyone does
try to mmap it because then TTM_PAGE_FLAG_SG would be set in in the
ttm_tt flags. But that flag is check before ttm_tt_populate in the ttm
vm fault handler.

So to be safe just add a check to verify_access() callback.

cpaul@redhat.com deba0a2af9 drm/dp/mst: Validate port in drm_dp_payload_send_msg()
With the joys of things running concurrently, there's always a chance
that the port we get passed in drm_dp_payload_send_msg() isn't actually
valid anymore. Because of this, we need to make sure we validate the
reference to the port before we use it otherwise we risk running into
various race conditions. For instance, on the Dell MST monitor I have
here for testing, hotplugging it enough times causes us to kernel panic:

[drm:intel_mst_enable_dp] 1
[drm:drm_dp_update_payload_part2] payload 0 1
[drm:intel_get_hpd_pins] hotplug event received, stat 0x00200000, dig 0x10101011, pins 0x00000020

Which occurs because of the hotplug event shown in the log, which ends
up causing DRM's dp helpers to drop the port we're updating the payload
on and panic.

Nishanth Menon 38a7a73e8e rtc: ds1307: Use irq when available for wakeup-source device
With commit 8bc2a40730 ("rtc: ds1307: add support for the
DT property 'wakeup-source'") we lost the ability for rtc irq
functionality for devices that are actually hooked on a real IRQ
line and have capability to wakeup as well. This is not an expected
behavior. So, instead of just not requesting IRQ, skip the IRQ
requirement only if interrupts are not defined for the device.
