vga_switcheroo_client_ops has always been declared const since its
introduction with 26ec685ff9d9 ("vga_switcheroo: Introduce struct
vga_switcheroo_client_ops").
Do so for vga_switcheroo_handler as well.

Add new RF tuner gain control named RF Gain. That is aimed for first
amplifier chip right after antenna connector.
There is existing LNA Gain control, which is quite same, but it is
aimed for cases amplifier is integrated to tuner chip. Some designs
have both, as almost all recent tuner silicons has integrated LNA/RF

SDR receiver has ADC (Analog-to-Digital Converter) and SDR transmitter
has DAC (Digital-to-Analog Converter). Originally I though it could
be good idea to have own type for receiver and transmitter, but now I
feel one common type for SDR is enough. So lets rename it.

Prepare to divide videobuf2
- Separate vb2 trace events from v4l2 trace event.
- Make wrapper functions that will move to v4l2-side.
- Make vb2_core_* functions that will remain in core-side.
- Add a callback function table for buffer operation which makes vb2-core
to be able to invoke a v4l2-side functions.

A lot of component based DRM drivers use a variant of the same code
as the probe function. They bind the crtc ports in the first iteration
and then scan through the child nodes and bind the encoders attached
to the remote endpoints. Factor the common code into a separate
function called drm_of_component_probe() in order to increase code
reuse.

Some code may perform racy by design memory reads. This could be
harmless, yet such code may produce KASAN warnings.
To hide such accesses from KASAN this patch introduces
READ_ONCE_NOCHECK() macro. KASAN will not check the memory
accessed by READ_ONCE_NOCHECK(). The KernelThreadSanitizer
(KTSAN) is going to ignore it as well.
This patch creates __read_once_size_nocheck() a clone of
__read_once_size(). The only difference between them is
'no_sanitized_address' attribute appended to '*_nocheck'
function. This attribute tells the compiler that instrumentation
of memory accesses should not be applied to that function. We
declare it as static '__maybe_unsed' because GCC is not capable
to inline such function:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=67368
With KASAN=n READ_ONCE_NOCHECK() is just a clone of READ_ONCE().

Add a new branch sample type to cover only call branches (function calls).
The current ANY_CALL included direct, indirect calls and far jumps.
We want to be able to differentiate indirect from direct calls. Therefore
we introduce PERF_SAMPLE_BRANCH_CALL. The implementation is up to each
architecture.

Commit:
b20112edeadf ("perf/x86: Improve accuracy of perf/sched clock")
allowed the time_shift value in perf_event_mmap_page to be as much
as 32. Unfortunately the documented algorithms for using time_shift
have it shifting an integer, whereas to work correctly with the value
32, the type must be u64.
In the case of perf tools, Intel PT decodes correctly but the timestamps
that are output (for example by perf script) have lost 32-bits of
granularity so they look like they are not changing at all.
Fix by limiting the shift to 31 and adjusting the multiplier accordingly.
Also update the documentation of perf_event_mmap_page so that new code
based on it will be more future-proof.

stop_machine_unpark()
1. Change smpboot_unpark_thread() to check ->selfparking, just
like smpboot_park_thread() does.
2. Introduce stop_machine_unpark() which sets ->enabled and calls
kthread_unpark().
3. Change smpboot_thread_call() and cpu_stop_init() to call
stop_machine_unpark() by hand.
This way:
- IMO the ->selfparking logic becomes more consistent.
- We can kill the smp_hotplug_thread->pre_unpark() method.
- We can easily unpark the stopper thread earlier. Say, we
can move stop_machine_unpark() from smpboot_thread_call()
to sched_cpu_active() as Peter suggests.

cpu_stop_park()
cpu_stop_queue_work() checks stopper->enabled before it queues the
work, but ->enabled == T can only guarantee cpu_stop_signal_done()
if we race with cpu_down().
This is not enough for stop_two_cpus() or stop_machine(), they will
deadlock if multi_cpu_stop() won't be called by one of the target
CPU's. stop_machine/stop_cpus are fine, they rely on stop_cpus_mutex.
But stop_two_cpus() has to check cpu_active() to avoid the same race
with hotplug, and this check is very unobvious and probably not even
correct if we race with cpu_up().
Change cpu_down() pass to clear ->enabled before cpu_stopper_thread()
flushes the pending ->works and returns with KTHREAD_SHOULD_PARK set.
Note also that smpboot_thread_call() calls cpu_stop_unpark() which
sets enabled == T at CPU_ONLINE stage, so this CPU can't go away until
cpu_stopper_thread() is called at least once. This all means that if
cpu_stop_queue_work() succeeds, we know that work->fn() will be called.

For generating modalias entries automatically, move the definition of
struct hda_device_id to linux/mod_devicetable.h and add the handling
of this record in file2alias helper. The new modalias is represented
with combination of vendor id, device id, and api version as
"hdaudio:vNrNaN".
This patch itself doesn't convert the existing modaliases. Since they
were added manually, this patch won't give any regression by itself at
this point.

For distinguishing the difference between HDA legacy and ext codec
driver entries, we need to expose the value corresponding to type
field. This patch adds a new field, api_version, to hda_device_id
struct, so that this information is embedded in modalias string.
Although the information is basically redundant (struct hdac_device
already has type field), the helper that extracts from
MODULE_DEVICE_TABLE() won't take it account except for the exported
table entries themselves. So we need to put the same information in
the table, too.

On atomic drivers we can dig out the primary plane rotation from the
plane state instead of looking at the legacy crtc->invert_dimensions
flag. The flag is not set by anyone except omapdrm, and it would be
racy to set it the same way in the atomic helpers.
v2: Kill crtc->invert_dimensions totally since omap is state based
already and no one else ever used it (Matt)

Compared to wrapping the final kref_put with dev->struct_mutex this
allows us to only acquire the offset manager look both in the final
cleanup and in the lookup. Which has the upside that no locks leak out
of the core abstractions. But it means that we need to hold a
temporary reference to the object while checking mmap constraints, to
make sure the object doesn't disappear. Extended the critical region
would have worked too, but would result in more leaky locking.
Also, this is the final bit which required dev->struct_mutex in gem
core, now modern drivers can be completely struct_mutex free!
This needs a new drm_vma_offset_exact_lookup_locked and makes both
drm_vma_offset_exact_lookup and drm_vma_offset_lookup unused.
v2: Don't leak object references in failure paths (David).
v3: Add a comment from Chris explaining how the ordering works, with
the slight adjustment that I dropped any mention of struct_mutex since
with this patch it's now immaterial ot core gem.

Pretty soon only some drivers will need dev->struct_mutex in their
gem_free_object callbacks. Hence it's really important to make sure
everything still keeps getting this right.
v2: Don't check for locking before we check for non-NULL obj. Spotted
by Dan Carpenter.

====================
Netfilter/IPVS updates for net-next
The following patchset contains Netfilter/IPVS updates for your net-next
tree. Most relevantly, updates for the nfnetlink_log to integrate with
conntrack, fixes for cttimeout and improvements for nf_queue core, they are:
1) Remove useless ifdef around static inline function in IPVS, from
Eric W. Biederman.
2) Simplify the conntrack support for nfnetlink_queue: Merge
nfnetlink_queue_ct.c file into nfnetlink_queue_core.c, then rename it back
to nfnetlink_queue.c
3) Use y2038 safe timestamp from nfnetlink_queue.
4) Get rid of dead function definition in nf_conntrack, from Flavio
Leitner.
5) Attach conntrack support for nfnetlink_log.c, from Ken-ichirou MATSUZAWA.
This adds a new NETFILTER_NETLINK_GLUE_CT Kconfig switch that
controls enabling both nfqueue and nflog integration with conntrack.
The userspace application can request this via NFULNL_CFG_F_CONNTRACK
configuration flag.
6) Remove unused netns variables in IPVS, from Eric W. Biederman and
Simon Horman.
7) Don't put back the refcount on the cttimeout object from xt_CT on success.
8) Fix crash on cttimeout policy object removal. We have to flush out
the cttimeout extension area of the conntrack not to refer to an unexisting
object that was just removed.
9) Make sure rcu_callback completion before removing nfnetlink_cttimeout
module removal.
10) Fix compilation warning in br_netfilter when no nf_defrag_ipv4 and
nf_defrag_ipv6 are enabled. Patch from Arnd Bergmann.
11) Autoload ctnetlink dependencies when NFULNL_CFG_F_CONNTRACK is
requested. Again from Ken-ichirou MATSUZAWA.
12) Don't use pointer to previous hook when reinjecting traffic via
nf_queue with NF_REPEAT verdict since it may be already gone. This
also avoids a deadloop if the userspace application keeps returning
NF_REPEAT.
13) A bunch of cleanups for netfilter IPv4 and IPv6 code from Ian Morris.
14) Consolidate logger instance existence check in nfulnl_recv_config().
15) Fix broken atomicity when applying configuration updates to logger
instances in nfnetlink_log.
16) Get rid of the .owner attribute in our hook object. We don't need
this anymore since we're dropping pending packets that have escaped
from the kernel when unremoving the hook. Patch from Florian Westphal.
17) Remove unnecessary rcu_read_lock() from nf_reinject code, we always
assume RCU read side lock from .call_rcu in nfnetlink. Also from Florian.
18) Use static inline function instead of macros to define NF_HOOK() and
NF_HOOK_COND() when no netfilter support in on, from Arnd Bergmann.

At the time of commit fff326990789 ("tcp: reflect SYN queue_mapping into
SYNACK packets") we had little ways to cope with SYN floods.
We no longer need to reflect incoming skb queue mappings, and instead
can pick a TX queue based on cpu cooking the SYNACK, with normal XPS
affinities.
Note that all SYNACK retransmits were picking TX queue 0, this no longer
is a win given that SYNACK rtx are now distributed on all cpus.

If a EXT4 filesystem utilizes JBD2 journaling and an error occurs, the
journaling will be aborted first and the error number will be recorded
into JBD2 superblock and, finally, the system will enter into the
panic state in "errors=panic" option. But, in the rare case, this
sequence is little twisted like the below figure and it will happen
that the system enters into panic state, which means the system reset
in mobile environment, before completion of recording an error in the
journal superblock. In this case, e2fsck cannot recognize that the
filesystem failure occurred in the previous run and the corruption
wouldn't be fixed.
Task A Task B
ext4_handle_error()
-> jbd2_journal_abort()
-> __journal_abort_soft()
-> __jbd2_journal_abort_hard()
| -> journal->j_flags |= JBD2_ABORT;
|
| __ext4_abort()
| -> jbd2_journal_abort()
| | -> __journal_abort_soft()
| | -> if (journal->j_flags & JBD2_ABORT)
| | return;
