1b2de5d039 mm/cow: don't bother write protecting already write-protected pages
This is not normally noticeable, but repeated forks are unnecessarily
expensive because they repeatedly dirty the parent page tables during
the page table copy operation.

It's trivial to just avoid write protecting the page table entry if it
was already not writable.

This patch was inspired by

    https://bugzilla.kernel.org/show_bug.cgi?id=200447

which points to an ancient "waste time re-doing fork" issue in the
presence of lots of signals.

That bug was fixed by Eric Biederman's signal handling series
culminating in commit c3ad2c3b02 ("signal: Don't restart fork when
signals come in"), but the unnecessary work for repeated forks is still
work just fixing, particularly since the fix is trivial.

e0fcfe1f1a hpfs: remove unnecessary checks on the value of r when assigning error code
At the point where r is being checked for different values, r is always
going to be equal to 2 as the previous if statements jump to end or end1
if r is not 2.  Hence the assignment to err can be simplified to just
err an assignment without any checks on the value or r.

Thanks for your work in this area. I still remember the first linux

his libata error handling work. Before that, it was basically a crap

Earlier used to post the current command without checking queue full
     after backlog submissions. So, post the current command only after
     confirming the space in queue after backlog submissions.

     Maintain host write index instead of reading device registers
     to get the next free slot to post the command.

0522236d4f crypto: vmx - Fix sleep-in-atomic bugs
This patch fixes sleep-in-atomic bugs in AES-CBC and AES-XTS VMX
implementations. The problem is that the blkcipher_* functions should
not be called in atomic context.

The bugs can be reproduced via the AF_ALG interface by trying to
encrypt/decrypt sufficiently large buffers (at least 64 KiB) using the
VMX implementations of 'cbc(aes)' or 'xts(aes)'. Such operations then
trigger BUG in crypto_yield():

c2b24c36e0 crypto: arm64/aes-gcm-ce - fix scatterwalk API violation
Commit 71e52c278c ("crypto: arm64/aes-ce-gcm - operate on
two input blocks at a time") modified the granularity at which
the AES/GCM code processes its input to allow subsequent changes
to be applied that improve performance by using aggregation to
process multiple input blocks at once.

For this reason, it doubled the algorithm's 'chunksize' property
to 2 x AES_BLOCK_SIZE, but retained the non-SIMD fallback path that
processes a single block at a time. In some cases, this violates the
skcipher scatterwalk API, by calling skcipher_walk_done() with a
non-zero residue value for a chunk that is expected to be handled
in its entirety. This results in a WARN_ON() to be hit by the TLS
self test code, but is likely to break other user cases as well.
Unfortunately, none of the current test cases exercises this exact
code path at the moment.

e5b954e8d1 crypto: aesni - Use unaligned loads from gcm_context_data
A regression was reported bisecting to 1476db2d12
"Move HashKey computation from stack to gcm_context".  That diff
moved HashKey computation from the stack, which was explicitly aligned
in the asm, to a struct provided from the C code, depending on
AESNI_ALIGN_ATTR for alignment.   It appears some compilers may not
align this struct correctly, resulting in a crash on the movdqa
instruction when attempting to encrypt or decrypt data.

Fix by using unaligned loads for the HashKeys.  On modern
hardware there is no perf difference between the unaligned and
aligned loads.  All other accesses to gcm_context_data already use
unaligned loads.

below the tick boundary and deep state B with target residency
significantly above it, are available and the predicted idle
duration is above the tick boundary, but below the target residency
of state B, state A will be selected and the CPU may spend indefinite
amount of time in it, which is not quite energy-efficient.

However, if the tick has not been stopped yet and the governor is
about to select a shallow idle state for the CPU even though the idle
duration predicted by it is above the tick boundary, it should be
fine to wake up the CPU early, so the tick can be retained then and
the governor will have a chance to select a deeper state when it runs
next time.

[Note that when this really happens, it will make the idle duration
 predictor believe that the CPU might be idle longer than predicted,
 which will make it more likely to predict longer idle durations going
 forward, but that will also cause deeper idle states to be selected
 going forward, on average, which is what's needed here.]

Jeff Kirsher says:

====================
Intel Wired LAN Driver Updates 2018-08-24

This series contains fixes to e1000, igb, ixgb, ixgbe and i40e.

YueHaibing from Huawei provides a change to use dma_zalloc_coherent()
instead of calls to allocator followed by a memset for ixgb.

Bo Chen provides a couple of fixes for e1000, first by adding a check to
prevent a NULL pointer dereference.  The second change is to clean up a
possible resource leak on old transmit and receive rings when the device
is not up.

Jesus fixes an issue in the usage of an advanced transmit context
descriptor for retrieving the timestamp of a packet for AF_PACKET if the
IGB_TX_FLAGS_VLAN is not set in igb.

Jia-Ju Bai provides several patches which replace GFP_ATOMIC with
GFP_KERNEL, when using kzalloc() and kcalloc() which is not necessary.
Also found an instance of mdelay() call which could be replaced with
msleep().

Tony fixes ixgbe to allow MTU changes with XDP, by adding checks to
ensure only supported values and return -EINVAL for when it is not
supported.

Sebastian fixed an issue that was not clearing VF mailbox memory and
ensure queues are re-enabled correctly.

Martyna fixes a transmit timeout when DCB is configured when bringing up
an interface.

Jake fixes a previous commit which accidentally reversed the check of
the data pointer, so we can accurately count the size of the stats.

a92bab8919 of: thermal: Allow multiple devices to share cooling map
A cooling map entry may now contain a list of phandles and their
arguments representing multiple devices which share the trip point.

This patch updates the thermal OF core to parse them properly. The trip
point and contribution value is shared by multiple cooling devices now
and so a new structure is created, struct __thermal_cooling_bind_param,
which represents a cooling device and its min/max states and the
existing struct __thermal_bind_params now contains an array of this new
cooling device structure.

Tested on Hikey960.

f1599f9e4c thermal: qcom-spmi: Use PMIC thermal stage 2 for critical trip points
There are three thermal stages defined in the PMIC:

stage 1: warning
stage 2: system should shut down
stage 3: emergency shut down

By default the PMIC assumes that the OS isn't doing anything and thus
at stage 2 it does a partial PMIC shutdown and at stage 3 it kills
all power. When switching between thermal stages the PMIC generates an
interrupt which is handled by the driver. The partial PMIC shutdown at
stage 2 can be disabled by software, which allows the OS to initiate a
shutdown at stage 2 with a thermal zone configured accordingly.

If a critical trip point is configured in the thermal zone the driver
adjusts the stage 1-3 temperature thresholds to (closely) match the
critical temperature with a stage 2 threshold (125/130/135/140 °C).
If a suitable match is found the partial shutdown at stage 2 is
disabled. If for some reason the system doesn't shutdown at stage 2
the emergency shutdown at stage 3 kicks in.

The partial shutdown at stage 2 remains enabled in these cases:
- no critical trip point defined
- the temperature of the critical trip point is < 125°C
- the temperature of the critical trip point is > 140°C and no
  ADC channel is configured (thus the OS is not notified when the critical
  temperature is reached)

97b27dd33d dt-bindings: thermal: qcom-spmi-temp-alarm: Improve thermal zone in example
The current example for a thermal zone isn't very useful as reference
since it would result in a hardware shutdown at 145°C, instead of
allowing the system to try to shutdown gracefully. Without an ADC
channel a maximum of two trip points is useful in practice for this
sensor, with temperatures corresponding to the stage 1 and stage 2
'hardware trip points'. A critical trip point at stage 2 may allow the
system to shutdown before a hardware shutdown at stage 3 kicks in. It
should be noted though that by default the chip performs a 'partial
shutdown' when the temperature reaches stage 2, which may prevent an
orderly shutdown. The 'partial shutdown' can be disabled by software.

99da0b3539 drm/i915: WARN() if we can't lookup_power_well()
None of the current lookup_power_well() callers are actually checking
for NULL return values, they all just use the pointer right away.  The
first idea was to replace these theoretical segfaults with a BUG()
since this would at least make our code a little more explicit to the
reader. It was suggested that just converting the BUG() to a WARN()
and returning any power well would probably be better since it would
still keep the system running while at the same time exposing the
driver bug.

We can only hit this NULL/BUG()/WARN() condition if we try to lookup a
power well that isn't defined on a given platform. If that ever
happens, we have to fix our code, making it lookup the correct power
well. Because of this, I don't think it's worth trying to implement
error checking in every caller. Improving our CI system will be a
better use of our time once a bug is found in the wild.

v2: Avoid the BUG() with a WARN() return a random PW (Michal).

39d1e234e1 drm/i915/icl: implement the tc/legacy HPD {dis,}connect flows
Unlike the other ports, TC ports are not available to use as soon as
we get a hotplug. The TC PHYs can be shared between multiple
controllers: display, USB, etc. As a result, handshaking through FIA
is required around connect and disconnect to cleanly transfer
ownership with the controller and set the type-C power state.

This patch implements the flow sequences described by our
specification. We opt to grab ownership of the ports as soon as we get
the hotplugs in order to simplify the interactions and avoid surprises
in the user space side. We may consider changing this in the future,
once we improve our testing capabilities on this area.

v2:
 * This unifies the DP and HDMI patches so we can discuss everything
   at once so people looking at random single patches can actually
   understand the direction.
 * I found out the spec was updated a while ago. There's a small
   difference in the connect flow and the patch was updated for that.
 * Our spec also now gives a good explanation on what is really
   happening. As a result, comments were added.
 * Add some more comments as requested by Rodrigo (Rodrigo).
v3:
 * Downgrade a DRM_ERROR that shouldn't ever happen but we can't act
   on in case it does (Chris).

BSpec: 21750, 4250.

aa5b1054ba powerpc fixes for 4.19 #2
- An implementation for the newly added hv_ops->flush() for the OPAL hvc
    console driver backends, I forgot to apply this after merging the hvc driver
    changes before the merge window.
 
  - Enable all PCI bridges at boot on powernv, to avoid races when multiple
    children of a bridge try to enable it simultaneously. This is a workaround
    until the PCI core can be enhanced to fix the races.
 
  - A fix to query PowerVM for the correct system topology at boot before
    initialising sched domains, seen in some configurations to cause broken
    scheduling etc.
 
  - A fix for pte_access_permitted() on "nohash" platforms.
 
  - Two commits to fix SIGBUS when using remap_pfn_range() seen on Power9 due to
    a workaround when using the nest MMU (GPUs, accelerators).
 
  - Another fix to the VFIO code used by KVM, the previous fix had some bugs
    which caused guests to not start in some configurations.
 
  - A handful of other minor fixes.

a5ec8332d4 drm: Add per-plane pixel blend mode property
Pixel blend modes represent the alpha blending equation
selection, describing how the pixels from the current
plane are composited with the background.

Adds a pixel_blend_mode to drm_plane_state and a
blend_mode_property to drm_plane, and related support
functions.

Defines three blend modes in drm_blend.h.

Changes since v1:
 - Moves the blending equation into the DOC comment
 - Refines the comments of drm_plane_create_blend_mode_property to not
   enumerate the #defines, but instead the string values
 - Uses fg.* instead of pixel.* and plane_alpha instead of plane.alpha
Changes since v2:
 - Refines the comments of drm_plane_create_blend_mode_property:
      1) Puts the descriptions (after the ":") on a new line
      2) Adds explaining why @supported_modes need PREMUL as default
Changes since v3:
 - Refines drm_plane_create_blend_mode_property(). drm_property_add_enum()
   can calculate the index itself just fine, so no point in having the
   caller pass it in.
 - Since the current DRM assumption is that alpha is premultiplied
   as default, define DRM_MODE_BLEND_PREMULTI as 0 will be better.
 - Refines some comments.
Changes since v4:
 - Adds comments in drm_blend.h.
 - Removes setting default value in drm_plane_create_blend_mode_property()
   as it is already in __drm_atomic_helper_plane_reset().
 - Fixes to use state->pixel_blend_mode instead of using
   plane->state->pixel_blend_mode in reset function.
 - Rebases on drm-misc-next.
