drm/nouveau/secboot: check that WPR region is properly set
The ACR firmware may return no error but fail nonetheless. Such cases
can be detected by verifying that the WPR region has been properly set
in FB. If this is not the case, this is an error, but the unload
firmware should still not be run.

PMU support has been enabled for r352 ACR, but it must remain optional
if we want to preserve existing user-space that do not include it. Allow
ACR to be instanciated with a list of optional LS falcons, that will not
produce a fatal error if their firmware is not loaded. Also change the
secure boot bootstrap logic to be able to fall back to legacy behavior
if it turns out the boot falcon's LS firmware cannot be loaded.

Adapt secboot's behavior if a PMU firmware is present, in particular
the way LS falcons are reset. Without PMU firmware, secboot needs to be
performed again from scratch so all LS falcons are reset. With PMU
firmware, we can ask the PMU's ACR unit to reset a specific falcon
through a PMU message.
As we must preserve the old behavior to avoid breaking user-space, add a
few conditionals to the way falcons are reset.

drm/nouveau/secboot: support for loading LS PMU firmware

A message queue firmware implements a specific protocol allowing the
host to send "commands" to a falcon, and the falcon to reply using
"messages". This patch implements the common part of this protocol and
defines the interface that the host can use.
Due to the way the firmware is developped internally at NVIDIA (where
kernel driver and firmware evolve in lockstep), firmwares taken at
different points in time can have frustratingly subtle differences that
must be taken into account. This code is architectured to make
implementing such differences as easy as possible.

drm/nouveau/secboot: add LS firmware post-run hooks

invoked right after the HS firmware is executed. This allows them to

drm/nouveau/priv: punt messages to debug level
Ideally we'd be able to keep these at a more obvious error level, as
they're a good indication of us doing something wrong.
However, NVIDIA's FECS/GPCCS firmware touches registers that trigger
priv ring faults, and we can't do anything to fix that ourselves due
to the need for them to be signed by NVIDIA.
This issue was reported a while back, but hasn't been fixed, so, for
now we will hide the messages to prevent spamming Optimus users with
messages whenever the NVIDIA GPU is powered off and on again.

drm/vmwgfx: Work around drm removal of control nodes
vmware tools has a daemon that gets layout information from the GUI and
forwards it to DRM so that the modesetting code can set preferred connector
locations and modes. This daemon was using control nodes but since control
nodes were just removed, make it possible for the daemon to use render- or
primary nodes instead. This is a bit ugly but will allow drm to proceed with
removal of the mostly unused control-node code and allow vmware to proceed
with fixing up automatic layout settings for gnome-shell/wayland.

KernelVersion: 4.11
Description:
Last hardware set brightness level for this LED. Some LEDs
may be changed autonomously by hardware/firmware. Only LEDs
where this happens and the driver can detect this, will
have this file.
This file supports poll() to detect when the hardware
changes the brightness.
Reading this file will return the last brightness level set
by the hardware, this may be different from the current
brightness.
Drivers which want to support this, simply add LED_BRIGHT_HW_CHANGED to
their flags field and call led_classdev_notify_brightness_hw_changed()
with the hardware set brightness when they detect a hardware / firmware
triggered brightness change.

platform/x86: asus-wireless: Use per-HID HSWC parameters
Some Asus machines use 0x4/0x5 as their LED on/off values, while others
use 0x0/0x1, as shown in the DSDT excerpts below. Luckily it seems this
behavior is tied to different HIDs, after looking at 44 DSDTs from
different Asus models.
Another small difference is that a few of them call GWBL instead of
OWGS, and SWBL instead of OWGD. That does not seem to make a difference
for asus-wireless, and is additional reasoning to not try to call these

lib: update LZ4 compressor module
Patch series "Update LZ4 compressor module", v7.
This patchset updates the LZ4 compression module to a version based on
LZ4 v1.7.3 allowing to use the fast compression algorithm aka LZ4 fast
which provides an "acceleration" parameter as a tradeoff between high
compression ratio and high compression speed.
We want to use LZ4 fast in order to support compression in lustre and
(mostly, based on that) investigate data reduction techniques in behalf
of storage systems.
Also, it will be useful for other users of LZ4 compression, as with LZ4
fast it is possible to enable applications to use fast and/or high
compression depending on the usecase. For instance, ZRAM is offering a
LZ4 backend and could benefit from an updated LZ4 in the kernel.
[PATCH 1/5] lib: Update LZ4 compressor module
[PATCH 2/5] lib/decompress_unlz4: Change module to work with new LZ4 module version
[PATCH 3/5] crypto: Change LZ4 modules to work with new LZ4 module version
[PATCH 4/5] fs/pstore: fs/squashfs: Change usage of LZ4 to work with new LZ4 version
[PATCH 5/5] lib/lz4: Remove back-compat wrappers
This patch (of 5):
Update the LZ4 kernel module to LZ4 v1.7.3 by Yann Collet. The kernel
module is inspired by the previous work by Chanho Min. The updated LZ4
module will not break existing code since the patchset contains
appropriate changes.
API changes:
New method LZ4_compress_fast which differs from the variant available in
kernel by the new acceleration parameter, allowing to trade compression
ratio for more compression speed and vice versa.
LZ4_decompress_fast is the respective decompression method, featuring a
very fast decoder (multiple GB/s per core), able to reach RAM speed in
multi-core systems. The decompressor allows to decompress data
compressed with LZ4 fast as well as the LZ4 HC (high compression)
algorithm.
Also the useful functions LZ4_decompress_safe_partial and
LZ4_compress_destsize were added. The latter reverses the logic by
trying to compress as much data as possible from source to dest while
the former aims to decompress partial blocks of data.
A bunch of streaming functions were also added which allow
compressig/decompressing data in multiple steps (so called "streaming
mode").
The methods lz4_compress and lz4_decompress_unknownoutputsize are now
known as LZ4_compress_default respectivley LZ4_decompress_safe. The old
methods will be removed since there's no callers left in the code.
...meaning that it currently is not being built as a module by anyone.
Lets remove the couple traces of modular infrastructure use, so that
when reading the code there is no doubt it is builtin-only.
Since module_init translates to device_initcall in the non-modular case,
the init ordering becomes slightly earlier when we change it to use
subsys_initcall as done here. However, since it is a self contained
test, this shouldn't be an issue and subsys_initcall seems like a better
fit for this particular case.
We also delete the MODULE_LICENSE tag since that information is now
contained at the top of the file in the comments.

kasan: drain quarantine of memcg slab objects
Per memcg slab accounting and kasan have a problem with kmem_cache
destruction.
- kmem_cache_create() allocates a kmem_cache, which is used for
allocations from processes running in root (top) memcg.
- Processes running in non root memcg and allocating with either
__GFP_ACCOUNT or from a SLAB_ACCOUNT cache use a per memcg
kmem_cache.
- Kasan catches use-after-free by having kfree() and kmem_cache_free()
defer freeing of objects. Objects are placed in a quarantine.
- kmem_cache_destroy() destroys root and non root kmem_caches. It takes
care to drain the quarantine of objects from the root memcg's
kmem_cache, but ignores objects associated with non root memcg. This
causes leaks because quarantined per memcg objects refer to per memcg
kmem cache being destroyed.
To see the problem:
1) create a slab cache with kmem_cache_create(,,,SLAB_ACCOUNT,)
2) from non root memcg, allocate and free a few objects from cache
3) dispose of the cache with kmem_cache_destroy() kmem_cache_destroy()
will trigger a "Slab cache still has objects" warning indicating
that the per memcg kmem_cache structure was leaked.
Fix the leak by draining kasan quarantined objects allocated from non
root memcg.
Racing memcg deletion is tricky, but handled. kmem_cache_destroy() =>
shutdown_memcg_caches() => __shutdown_memcg_cache() => shutdown_cache()
flushes per memcg quarantined objects, even if that memcg has been
rmdir'd and gone through memcg_deactivate_kmem_caches().
This leak only affects destroyed SLAB_ACCOUNT kmem caches when kasan is
enabled. So I don't think it's worth patching stable kernels.
