DAX handling of COW faults has wrong locking sequence:
dax_fault does i_mmap_lock_read
do_cow_fault does i_mmap_unlock_write
Ross's commit[1] missed a fix[2] that Kirill added to Matthew's
commit[3].
Original COW locking logic was introduced by Matthew here[4].
This should be applied to v4.3 as well.
[1] 0f90cc6609c7 mm, dax: fix DAX deadlocks
[2] 52a2b53ffde6 mm, dax: use i_mmap_unlock_write() in do_cow_fault()
[3] 843172978bb9 dax: fix race between simultaneous faults
[4] 2e4cdab0584f mm: allow page fault handlers to perform the COW

The recently added mt8173 cpufreq driver relies on the cpu topology
that is always present on ARM64 but optional on ARM32:
drivers/cpufreq/mt8173-cpufreq.c: In function 'mtk_cpufreq_init':
drivers/cpufreq/mt8173-cpufreq.c:441:30: error: 'cpu_topology' undeclared (first use in this function)
cpumask_copy(policy->cpus, &cpu_topology[policy->cpu].core_sibling);
This refines the Kconfig dependencies so that we can still build on
ARM32, but only if COMPILE_TEST is selected and the CPU topology
code is present.

There are two flavors of Atom cores to be supported by intel_pstate,
Silvermont and Airmont, so make the driver distinguish between them by
adding separate frequency tables.
Separate the CPU defaults params for each of them and match the CPU IDs

Rename symbol and function names starting with "BYT" or "byt" to
start with "ATOM" or "atom", respectively, so as to make it clear
that they may apply to Atom in general and not just to Baytrail
(the goal is to support several Atoms architectures eventually).
This should not lead to any functional changes.

Revert commit 37afb0003242 (cpufreq: intel_pstate: Use ACPI perf
configuration) that is reported to cause a regression to happen
on a system where invalid data are returned by the ACPI _PSS object.
Since that commit makes assumptions regarding the _PSS output
correctness that may turn out to be overly optimistic in general,
there is a concern that it may introduce regression on more
systems, so it's better to revert it now and we'll revisit the
underlying issue in the next cycle with a more robust solution.

The source and destination pointers are misplaced.
This will be like,
ether_addr_copy(data, bssid + ADDR2);
-> ether_addr_copy(bssid, data + ADDR2);
and also to use ether_addr_copy, it has to be proved that src/dst address are
properly aligned(2).

* ad5064
- Make sure the local i2c_write returns 0 on success rather than the
number of bytes transfered. Otherwise we report an error on all writes.
- Fix a shift for ad5629 and ad5669 which gives incorrect DAC output on
these parts.

* lpc32xx
- make sure clock is prepared before enabling.

- data byte order was reversed. Fix it.

- Internal temperature calculation was wrong if a different

A newly introduced function in include/net/sock.h passes a const
argument to smp_load_acquire:
static inline int sk_state_load(const struct sock *sk)
{
return smp_load_acquire(&sk->sk_state);
}
This cause an allmodconfig build failure, since our underlying
load-acquire implementation does not handle const types correctly:
include/net/sock.h: In function 'sk_state_load':
./arch/arm64/include/asm/barrier.h:71:3: error: read-only variable '___p1' used as 'asm' output
asm volatile ("ldarb %w0, %1" \
This patch fixes the problem by reusing the trick in READ_ONCE that
loads via a non-const member of an anonymous union. This has the
advantage of allowing us to use smp_load_acquire on packed structures
(e.g. arch_spinlock_t) as well as primitive types.

Clear device initiated resume variables once device is fully up and running
in U0 state.
Resume needs to be signaled for 20ms for usb2 devices before they can be
moved to U0 state.
An interrupt is triggered if a device initiates resume. As we handle the
event in interrupt context we can not sleep for 20ms, so we instead set
a resume flag, a timestamp, and start the roothub polling.
The roothub code will later move the port to U0 when it finds a port in
resume state with the resume flag set, and timestamp passed by 20ms.
A host initiated resume is however not done in interrupt context, and
host initiated resume code will directly signal resume, wait 20ms and then
move the port to U0.
These two codepaths can race, if we are in the middle of a host initated
resume, while sleeping for 20ms, we may handle a port event and find the
port in resume state. The port event handling code will assume the resume
was device initiated and set the resume flag and timestamp.
Root hub code will however not catch the port in resume state again as the
host initated resume code has already moved the port to U0.
The resume flag and timestamp will remain set for this port preventing port
from suspending again (LPM setting port to U3)
Fix this for now by always clearing the device initated resume parameters
once port is in U0

Function ep_ring_is_processing() checks the dequeue pointer
in endpoint context to know whether an endpoint is busy with
processing TRBs. This is not correct since dequeue pointer
field in an endpoint context is only valid when the endpoint
is in Halted or Stopped states. This buggy code causes audio
noise when playing sound with USB headset connected to host
controllers which support CFC (one of xhci 1.1 features).
This patch should exist in stable kernel since v4.3.

Existing Intel xHCI controllers require a delay of 1 mS,
after setting the CMD_RESET bit in command register, before
accessing any HC registers. This allows the HC to complete
the reset operation and be ready for HC register access.
Without this delay, the subsequent HC register access,
may result in a system hang, very rarely.
Verified CherryView / Braswell platforms go through over
5000 warm reboot cycles (which was not possible without
this patch), without any xHCI reset hang.

When diagnosing a unrelated bug for someone on irc, it would seem the hardware can
be brought up by the BIOS with the embedded displayport using the SPLL for spread spectrum.
Right now this is not handled well in i915, and it calculates the crtc needs to
be reprogrammed on the first modeset without SSC, but the SPLL itself was kept
active. Fix this by exposing SPLL as a shared pll that will not be returned
by intel_get_shared_dpll; you have to know it exists to use it.
Changes since v1:
- Create a separate dpll_hw_state.spll for spll, and use
separate pll functions for spll.

The asynchronous, merged implementations of AES in CBC, CTR and XTS
modes are preferred when available (i.e., when instantiating ablkciphers
explicitly). However, the synchronous core AES cipher combined with the
generic CBC mode implementation will produce a 'cbc(aes)' blkcipher that
is callable asynchronously as well. To prevent this implementation from
being used when the accelerated asynchronous implemenation is also
available, lower its priority to 250 (i.e., below the asynchronous
module's priority of 300).

As pointed out by Russell King in response to the proposed ARM version
of this code, the sequence to switch between the UEFI runtime mapping
and current's actual userland mapping (and vice versa) is potentially
unsafe, since it leaves a time window between the switch to the new
page tables and the TLB flush where speculative accesses may hit on
stale global TLB entries.
So instead, use non-global mappings, and perform the switch via the
ordinary ASID-aware context switch routines.

With gen < 9 we have had always 50Mhz units as our hw
ratio. With gen >= 9 the hw ratio changed to 16.667Mhz (50/3).
The result was that our gpu frequency tracing started to output
values 3 times larger than expected due to hardcoded scaling
value. Fix this by using Use intel_gpu_freq() when generating Mhz
value from ratio for 'intel_gpu_freq_change' trace event.

We would scan out the memory around them if an upscale was attempted,
and would just scan out incorrectly for downscaling.

vc4_plane_init() returns an ERR_PTR on error, it doesn't return NULL.
This was obviously intended because the next lines call
PTR_ERR(primary_plane) already.

Connector cannot be null because it is a list entry, ie accessed at an
offset from the positions of the list structure pointers themselves.

This reverts commit 00ee59271777 ("net: fix __netdev_update_features return
on ndo_set_features failure")
and adds a comment explaining why it's okay to return a value other than
0 upon error. Some drivers might actually change flags and return an
error so it's better to fire a spurious notification rather than miss
these.

While possibly in future we don't necessarily need to use
sk_buff_head.lock this is a rather larger change, as it affects the
af_unix fd garbage collector, diag and socket cleanups. This is too much
for a stable patch.
For the time being grab sk_buff_head.lock without disabling bh and irqs,
so don't use locked skb_queue_tail.
