In the similar way like we do for the platform data we propagate the device
properties. For example, in case of Intel LPSS drivers we may provide a
specific property to tell the actual device driver an additional information
such as platform name.

If multiple devices share single firmware node like it is case with MFD
devices, the same firmware node (ACPI) is assigned to all of them. The
function also modifies the shared firmware node in order to preserve
secondary firmware node of the device in question.
If the new device which is sharing the firmware node does not have
secondary node it will be NULL which will be assigned to the secondary node
of the shared firmware node losing all built-in properties.
Prevent this by setting the secondary firmware node only if the replacement
is non-NULL.
Print also warning if someone tries to overwrite secondary node that has
already been assigned.

Make it possible to pass built-in device properties to platform device
drivers. This is useful if the system does not have any firmware interface
like Device Tree or ACPI which provides these.
Properties associated with the platform device will be automatically
released when the corresponding device is removed.

It is convenient if the property set associated with the device secondary
firmware node is a copy of the original. This allows passing property set
from a stack for example for devices created dynamically. This also ties
the property set lifetime to the associated device.
Because of that we provide new function device_remove_property_set() that
is used to disassociate and release memory allocated for the property set.

The struct fwnode has notion of secondary fwnode. This is supposed to used
as fallback if the primary firmware interface (DT, ACPI) does not have the
property in question.
However, the current implementation never checks the secondary node which
prevents one to add default "built-in" properties to devices.
This patch adds fallback to the secondary fwnode if the primary fwnode
returns that the property does not exists.

We are comparing policy->governor against cpufreq_gov_ondemand to make
sure that we update sampling rate only for the concerned CPUs. But that
isn't enough.
In case of governor_per_policy, there can be multiple instances of
ondemand governor and we will always end up updating all of them with
current code. What we rather need to do, is to compare dbs_data with
poilcy->governor_data, which will match only for the policies governed
by dbs_data.
This code is also racy as the governor might be getting stopped at that
time and we may end up scheduling work for a policy, which we have just
disabled.
Fix that by protecting the entire function with &od_dbs_cdata.mutex,
which will prevent against races with policy START/STOP/etc.
After these locks are in place, we can safely get the policy via per-cpu
dbs_info.

If the chunks are enqueued successfully but sctp_cmd_interpreter()
return err to sctp_sendmsg() (mainly because of no mem), the chunks will
get re-queued, but we are dropping the reference and freeing them.
The fix is to just drop the reference on the datamsg just as it had
succeeded, as:
- if the chunks weren't queued, this is enough to get them freed.
- if they were queued, they will get freed when they finally get out or
discarded.

When a msg is sent, sctp will hold the chunks of this msg and then try
to enqueue them. But if the chunks are not enqueued in sctp_outq_tail()
because of the invalid state, sctp_cmd_interpreter() may still return
success to sctp_sendmsg() after calling sctp_outq_flush(), these chunks
will become orphans and will leak.
So we fix them by moving sctp_chunk_hold() to sctp_outq_tail(), where we
are sure that the chunk is going to get queued.

[Al Viro] The bug is in being too enthusiastic about optimizing ->setattr()
away - instead of "copy verbatim with metadata" + "chmod/chown/utimes"
(with the former being always safe and the latter failing in case of
insufficient permissions) it tries to combine these two. Note that copyup
itself will have to do ->setattr() anyway; _that_ is where the elevated
capabilities are right. Having these two ->setattr() (one to set verbatim
copy of metadata, another to do what overlayfs ->setattr() had been asked
to do in the first place) combined is where it breaks.

In case of a tx queue timeout every transmit is blocked until the
QCA7000 resets himself and triggers a sync which makes the driver
flushs the tx ring. So avoid this blocking situation by triggering
the sync immediately after the timeout. Waking the queue doesn't
make sense in this situation.

2 60290692739910 0x69a50 [0x38]: PERF_RECORD_EXIT(1252:1252):(1252:1252)
The reason is that the cpu contexts are processes each time
we call perf_event_task. I'm changing the perf_event_aux logic
to serve task_ctx and cpu contexts separately, which ensure we
don't get EXIT event generated twice on same cpu context.
This does not affect other auxiliary events, as they don't
use task_ctx at all.

The Huawei E3372 (12d1:157d) needs this quirk in MBIM mode
as well. Allow this by forcing the NTB to contain only a
single NDP, and add a device specific entry for this ID.
Due to the way Huawei use device IDs, this might be applied
to other modems as well. It is assumed that those modems
will be based on the same firmware and will need this quirk
too. If not, it will still not harm normal usage, although
multiplexing performance could be impacted.

Dmitry Vyukov reported that SCTP was triggering a WARN on socket destroy
related to disabling sock timestamp.
When SCTP accepts an association or peel one off, it copies sock flags
but forgot to call net_enable_timestamp() if a packet timestamping flag
was copied, leading to extra calls to net_disable_timestamp() whenever
such clones were closed.
The fix is to call net_enable_timestamp() whenever we copy a sock with
that flag on, like tcp does.

SCTP echoes a cookie o INIT ACK chunks that contains a timestamp, for
detecting stale cookies. This cookie is echoed back to the server by the
client and then that timestamp is checked.
Thing is, if the listening socket is using packet timestamping, the
cookie is encoded with ktime_get() value and checked against
ktime_get_real(), as done by __net_timestamp().
The fix is to sctp also use ktime_get_real(), so we can compare bananas
with bananas later no matter if packet timestamping was enabled or not.

There is a memleak when suspend/resume this driver version.
Currently the stmmac, during resume step, reallocates all the resources
but they are not released when suspend.
The patch is not to release these resources but the logic has been changed.
In fact, it is not necessary to free and reallocate all from scratch
because the memory data will be always preserved.
As final solution, the patch just reinit the descriptors and the rx/tx
pointers only when resume. Tested done on STi boxes.

This is because netdev_alloc_skb() fails and 'mdp->rx_skbuff[entry]' is left

Intel Wired LAN Driver Updates 2015-12-03
This series contains updates to ixgbe, i40e/i40evf, MAINTAINERS and e100.txt
Alex provides a fix for ixgbe where enabling SR-IOV and then bringing the
interface up was resulting in the PF MAC addresses getting into a bad state.
The workaround for this issue is to bring up the interface first and then
enable SR-IOV as this will trigger the reset in the existing code.
I clean up legacy license stuff in the e100.txt documentation and then
update the maintainers/reviewers list for our drivers.
Jesse fixes an issue with the i40e/i40evf drivers, where if the driver were
to happen to have a mutex held while the i40e_init_adminq() call was called,
the init_adminq might inadvertently call mutex_init on a lock that was held
which is a violation of the calling semantices.

When restarting a syscall with regs->ax == -ERESTART_RESTARTBLOCK,
regs->ax is assigned to a restart_syscall number. For x32 tasks, this
syscall number must have __X32_SYSCALL_BIT set, otherwise it will be
an x86_64 syscall number instead of a valid x32 syscall number. This
issue has been there since the introduction of x32.

MPX decodes instructions in order to tell which bounds register
was violated. Part of this decoding involves looking at the "REX
prefix" which is a special instrucion prefix used to retrofit
support for new registers in to old instructions.
The X86_REX_*() macros are defined to return actual bit values:
#define X86_REX_R(rex) ((rex) & 4)
*not* boolean values. However, the MPX code was checking for
them like they were booleans. This might have led to us
mis-decoding the "REX prefix" and giving false information out to
userspace about bounds violations. X86_REX_B() actually is bit 1,
so this is really only broken for the X86_REX_X() case.
Fix the conditionals up to tolerate the non-boolean values.
