Try to fix the code to actually clip the plane to the crtc bounds
instead of the user provided crtc coordinates (which would be a no-op
since those are exactly the coordinates before clipping).

authors
Sometimes a single patch is the result of multiple authors. As git only
can have one "author" of a patch, it is still good to properly give
credit to the other developers of a commit. To address this, document
the "Co-Developed-by:" tag which can be used to show other authors of
the patch.
Note, these other authors must also provide a Signed-off-by: tag as it
is their work that is being submitted here.

previous write
The hardware needs some time to process the information received in the
ExecList Submission Port, and expects us to not write anything more until
it has 'acknowledged' this new submission by sending an IDLE_ACTIVE or
PREEMPTED CSB event.
If we do not follow this, the driver could write new data into the ELSP
before HW had finishing fetching the previous one, putting us in
'undefined behaviour' space.
This seems to be the problem causing the spurious PREEMPTED & COMPLETE
events after a COMPLETE like the one below:
[] vcs0: sw rd pointer = 2, hw wr pointer = 0, current 'head' = 3.
[] vcs0: Execlist CSB[0]: 0x00000018 _ 0x00000007
[] vcs0: Execlist CSB[1]: 0x00000001 _ 0x00000000
[] vcs0: Execlist CSB[2]: 0x00000018 _ 0x00000007 <<< COMPLETE
[] vcs0: Execlist CSB[3]: 0x00000012 _ 0x00000007 <<< PREEMPTED & COMPLETE
[] vcs0: Execlist CSB[4]: 0x00008002 _ 0x00000006
[] vcs0: Execlist CSB[5]: 0x00000014 _ 0x00000006
The ELSP writes that lead to this CSB sequence show that the HW hadn't
started executing the previous execlist (the one with only ctx 0x6) by the
time the new one was submitted; this is a bit more clear in the data
show in the EXECLIST_STATUS register at the time of the ELSP write.
[] vcs0: ELSP[0] = 0x0_0 [execlist1] - status_reg = 0x0_302
[] vcs0: ELSP[1] = 0x6_fedb2119 [execlist0] - status_reg = 0x0_8302
[] vcs0: ELSP[2] = 0x7_fedaf119 [execlist1] - status_reg = 0x0_8308
[] vcs0: ELSP[3] = 0x6_fedb2119 [execlist0] - status_reg = 0x7_8308
Note that having to wait for this ack does not disable lite-restores,
although it may reduce their numbers.

When deleting a station or otherwise tearing down all aggregation
sessions, make sure to delete requested but not yet started ones,
to avoid the following scenario:
* session is requested, added to tid_start_tx[]
* ieee80211_ba_session_work() runs, gets past BLOCK_BA check
* ieee80211_sta_tear_down_BA_sessions() runs, locks &sta->ampdu_mlme.mtx,
e.g. while deleting the station - deleting all active sessions
* ieee80211_ba_session_work() continues since tear down flushes it, and
calls ieee80211_tx_ba_session_handle_start() for the new session, arms
the timer for it
* station deletion continues to __cleanup_single_sta() and frees the
session struct, while the timer is armed

construction
As the request will, in the following patch, implicitly invoke a
context-switch on construction, we should precede that with a GPU TLB
invalidation. Also, even before using GGTT, we always want to invalidate
the TLBs for any updates (as well as the ppgtt invalidates that are
unconditionally applied by execbuf). Since we almost always require the
TLB invalidate, do it unconditionally on request allocation and so we can
remove it from all other paths.

When cfg80211 is built as a module, everything is fine, and we
can keep the code as is; in fact, we have to, because there can
only be a single module_init().
When cfg80211 is built-in, however, it needs to initialize
before drivers (device_initcall/module_init), and thus used to
be at subsys_initcall(). I'd moved it to fs_initcall() earlier,
where it can remain. However, this is still too early because at
that point the key infrastructure hasn't been initialized yet,
so X.509 certificates can't be parsed yet.
To work around this problem, load the regdb keys only later in
a late_initcall(), at which point the necessary infrastructure
has been initialized.

For (P2P) client, it's wrong, because it exposes an internal

drm/i915/bdw: Avoid non-lite-restore preemptions
execlists has listened to (ACTIVE_IDLE | ELEMENT_SWITCH) for detecting
when one context completed and it either continued onto the next (in port
1) or idled. We would always see COMPLETE | ACTIVE_IDLE on the final
context-switch event, but on recent gen it appears that we now get
separate ACTIVE_IDLE and COMPLETE events. In particular, the ACTIVE_IDLE
events may not be coupled to a context (since it is a general state rather
than a specific context completion event).
v2: Update the history, execlists did originally start out by listening
to the COMPLETE event not ACTIVE_IDLE.
v3: Update preempt completion test to also use COMPLETE not ACTIVE_IDLE.

Moving the init_clock_gating() call from intel_modeset_init_hw() to

some workarounds on resume. This, for example, cause some kind of
corruption to appear at the top of my IVB Thinkpad X1 Carbon LVDS

When zero window is announced we can get into a situation where
connection stays around forever:
1. One side announces zero window.
2. Other side closes.
In this case, no FIN is sent (stuck in send queue).
Unless other side opens the window up again conntrack
stays in ESTABLISHED state for a very long time.
Lets alleviate this by lowering the timeout to RETRANS (5 minutes),
the other end should be sending zero window probes to keep the
connection established as long as a socket still exists.

The current implementation of the pad clock isn't quite correct. This
has the side-effect of being incompatible with the implementation for
Tegra186 (provided by the BPMP) and therefore would require a massive
change to the driver to cope with the differences. Instead, simply do
what Tegra186 does and add some code to fallback to the old behaviour
for existing device trees.

There is no need to #define the license of the driver, just put it in
the MODULE_LICENSE() line directly as a text string.
This allows tools that check that the module license matches the source
code license to work properly, as there is no need to unwind the
unneeded dereference, especially when the string is defined in a .h file
far away from the .c file it is used in.

The i2c adapter on DP AUX is purely a software construct. Linking
it to the device node of the parent device is wrong, as it leads to
2 devices sharing the same device node, which is bad practice, as
well as the i2c trying to populate children of the i2c adapter by
looking at the child device nodes of the parent device.

While computing slice mask for the free area we need make sure we only
search in the addr limit applicable for this mmap. We update the
slb_addr_limit after we request for a mmap above 128TB. But the
following mmap request with hint addr below 128TB should still limit
its search to below 128TB. ie. we should not use slb_addr_limit to
compute slice mask in this case. Instead, we should derive high addr
limit based on the mmap hint addr value.

The function to decide if one zcrypt queue is better than
another one compared two pointers instead of comparing the
values where the pointers refer to. So within the same
zcrypt card when load of each queue was equal just one queue
was used. This effect only appears on relatively lite load,
typically with one thread applications.
This patch fixes the wrong comparison and now the counters
show that requests are balanced equally over all available
queues within the cards.
There is no performance improvement coming with this fix.
As long as the queue depth for an APQN queue is not touched,
processing is not faster when requests are spread over
queues within the same card hardware. So this fix only
beautifies the lszcrypt counter printouts.

When searching the opcode offset table within find_insn() the check
"entry->opcode == 0" was intended to clarify that 1-byte opcodes, the
first one being 0, are special.
However there is no mnemonic for an illegal opcode starting with 0.
Therefore there is also no opcode offset table entry that matches,
which again means that the check never is true. Therefore just remove
the confusing check, and add a comment which hopefully explains how
this works.

If GCC_PLUGIN_RANDSTRUCT is enabled the members of task_struct will be
shuffled around. The offsets of the "pid" and "stack" members within
task_struct may not necessarily fit into 12 bits anymore, which causes
compile errors within __switch_to, since instructions are used, which
only have a 12 bit displacement field.
Therefore rework __switch_to, to allow for larger offsets.

This patch fixes the compiler error by adding function
topology_cpu_dedicated() to return false when this config option is

Whenever a cmd is received a reference is taken while looking up the
queue. The reference is removed after the cmd is done as the iod is
returned for reuse. The fod may be reused for a deferred (recevied but
no job context) cmd. Existing code removes the reference only if the
fod is not reused for another command. Given the fod may be used for
one or more ios, although a reference was taken per io, it won't be
matched on the frees.
Remove the reference on every fod free. This pairs the references to
each io.

This fixes using the NULL 'head' before getting the reference. It is
however possible the head will always be NULL, so this patch uses the
struct nvme_ns to get the ns_id field.

hmb descriptor idx out-of-bound occurs in case of below conditions.
preferred = 128MiB
chunk_size = 4MiB
hmmaxd = 1
Current code will not allow rmmod which will free hmb descriptors
to be done successfully in above case.
"descs[i]" will be set in for-loop without seeing any conditions
related to "max_entries" after a single "descs" was allocated by
(max_entries = 1) in this case.
Added a condition into for-loop to check index of descriptors.
