Print IRQ number used by DPC port, like AER/PME does. It provides
convenience to track DPC interrupts counts of certain port from
/proc/interrupts.

Previously we used "pos" or "aer_pos" for the offset of the AER Capability.
Use "aer" consistently and initialize it the same way everywhere. No

Commit c100beb9ccfb ("PCI/AER: Use only _OSC to determine AER ownership")
removed the use of HEST in determining AER ownership, but the AER driver
still used HEST to verify AER ownership in some of its APIs.
Per the ACPI spec v6.3, sec 18.3.2.4, some HEST table entries contain a
FIRMWARE_FIRST bit, but that bit does not tell us anything about ownership
of the AER capability.
Remove parsing of HEST to look for FIRMWARE_FIRST.
Add pcie_aer_is_native() for the places that need to know whether the OS
owns the AER capability.

With the advent of preempt-to-busy, a request may still be on the GPU as
we unwind. And in the case of a unpreemptible [due to HW] request, that
request will remain indefinitely on the GPU even though we have
returned it back to our submission queue, and cleared the active bit.
We only run the execution callbacks on transferring the request from our
submission queue to the execution queue, but if this is a bonded request
that the HW is waiting for, we will not submit it (as we wait for a
fresh execution) even though it is still being executed.
As we know that there are always preemption points between requests, we
know that only the currently executing request may be still active even
though we have cleared the flag. However, we do not precisely know which
request is in ELSP[0] due to a delay in processing events, and
furthermore we only store the last request in a context in our state
tracker.

When we push a virtual request onto the HW, we update the rq->engine to
point to the physical engine. A request that is then submitted by the
user that waits upon the virtual engine, but along the physical engine
in use, will then see that it is due to be submitted to the same engine
and take a shortcut (and be queued without waiting for the completion
fence). However, the virtual request may be preempted (either by higher
priority users, or by timeslicing) and removed from the physical engine
to be migrated over to one of its siblings. The dependent normal request
however is oblivious to the removal of the virtual request and remains
queued to execute on HW, believing that once it reaches the head of its
queue all of its predecessors will have completed executing!
v2: Beware restriction of signal->execution_mask prior to submission.

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]
sizeof(flexible-array-member) triggers a warning because flexible array
members have incomplete type[1]. There are some instances of code in
which the sizeof operator is being incorrectly/erroneously applied to
zero-length arrays and the result is zero. Such instances may be hiding
some bugs. So, this work (flexible-array member conversions) will also
help to get completely rid of those sorts of issues.
This issue was found with the help of Coccinelle.

On the ASUS laptop UX325JA/UX425JA, most of the media keys are not
working due to the ASUS WMI driver fails to be loaded. The ACPI error
as follows leads to the failure of asus_wmi_evaluate_method.
ACPI BIOS Error (bug): AE_AML_BUFFER_LIMIT, Field [IIA3] at bit offset/length 96/32 exceeds size of target Buffer (96 bits) (20200326/dsopcode-203)
No Local Variables are initialized for Method [WMNB]
ACPI Error: Aborting method \_SB.ATKD.WMNB due to previous error (AE_AML_BUFFER_LIMIT) (20200326/psparse-531)
The DSDT for the WMNB part shows that 5 DWORD required for local
variables and the 3rd variable IIA3 hit the buffer limit.
Method (WMNB, 3, Serialized)
{ ..
CreateDWordField (Arg2, Zero, IIA0)
CreateDWordField (Arg2, 0x04, IIA1)
CreateDWordField (Arg2, 0x08, IIA2)
CreateDWordField (Arg2, 0x0C, IIA3)
CreateDWordField (Arg2, 0x10, IIA4)
Local0 = (Arg1 & 0xFFFFFFFF)
If ((Local0 == 0x54494E49))
..
}
The limitation is determined by the input acpi_buffer size passed
to the wmi_evaluate_method. Since the struct bios_args is the data
structure used as input buffer by default for all ASUS WMI calls,
the size needs to be expanded to fix the problem.

chasis-type
The HP Stream x360 11-p000nd no longer report SW_TABLET_MODE state / events
with recent kernels. This model reports a chassis-type of 10 / "Notebook"
which is not on the recently introduced chassis-type whitelist
Commit de9647efeaa9 ("platform/x86: intel-vbtn: Only activate tablet mode
switch on 2-in-1's") added a chassis-type whitelist and only listed 31 /
"Convertible" as being capable of generating valid SW_TABLET_MOD events.
Commit 1fac39fd0316 ("platform/x86: intel-vbtn: Also handle tablet-mode
switch on "Detachable" and "Portable" chassis-types") extended the
whitelist with chassis-types 8 / "Portable" and 32 / "Detachable".
And now we need to exten the whitelist again with 10 / "Notebook"...
The issue original fixed by the whitelist is really a ACPI DSDT bug on
the Dell XPS 9360 where it has a VGBS which reports it is in tablet mode
even though it is not a 2-in-1 at all, but a regular laptop.
So since this is a workaround for a DSDT issue on that specific model,
instead of extending the whitelist over and over again, lets switch to
a blacklist and only blacklist the chassis-type of the model for which
the chassis-type check was added.
Note this also fixes the current version of the code no longer checking
if dmi_get_system_info(DMI_CHASSIS_TYPE) returns NULL.

QCA6390 memdump VSE sometimes come to bluetooth driver
with wrong sequence number as illustrated as follows:
frame # in dec: frame data in hex
1396: ff fd 01 08 74 05 00 37 8f 14
1397: ff fd 01 08 75 05 00 ff bf 38
1414: ff fd 01 08 86 05 00 fb 5e 4b
1399: ff fd 01 08 77 05 00 f3 44 0a
1400: ff fd 01 08 78 05 00 ca f7 41
it is mistook for controller missing packets, so results
in page fault after overwriting memdump buffer allocated.
Fixed by ignoring QCA6390 sequence number check and
checking buffer space before writing.

serdev_device_write()
serdev_device_write() is not appropriate at here because
serdev_device_write_wakeup() is not used to release completion hold
by the former at @write_wakeup member of struct serdev_device_ops.
Fix by using serdev_device_write_buf() instead of serdev_device_write().

Clear tuning_done flag while executing tuning to ensure vendor
specific HS400 settings are applied properly when the controller
is re-initialized in HS400 mode.
Without this, re-initialization of the qcom SDHC in HS400 mode fails
while resuming the driver from runtime-suspend or system-suspend.

This introduces mtdpstore, which is similar to mtdoops but more
powerful. It uses pstore/blk, and aims to store panic and oops logs to
a flash partition, where pstore can later read back and present as files
in the mounted pstore filesystem.
To make mtdpstore work, the "blkdev" of pstore/blk should be set
as MTD device name or MTD device number. For more details, see
Documentation/admin-guide/pstore-blk.rst
This solves a number of issues:
- Work duplication: both of pstore and mtdoops do the same job storing
panic/oops log. They have very similar logic, registering to kmsg
dumper and storing logs to several chunks one by one.
- Layer violations: drivers should provides methods instead of polices.
MTD should provide read/write/erase operations, and allow a higher
level drivers to provide the chunk management, kmsg dump
configuration, etc.
- Missing features: pstore provides many additional features, including
presenting the logs as files, logging dump time and count, and
supporting other frontends like pmsg, console, etc.

xdp_umem.c had overlapping changes between the 64-bit math fix
for the calculation of npgs and the removal of the zerocopy
memory type which got rid of the chunk_size_nohdr member.
The mlx5 Kconfig conflict is a case where we just take the
net-next copy of the Kconfig entry dependency as it takes on
the ESWITCH dependency by one level of indirection which is
what the 'net' conflicting change is trying to ensure.

Johannes Berg says:
====================
Another set of changes, including
* many 6 GHz changes, though it's not _quite_ complete
(I left out scanning for now, we're still discussing)
* allow userspace SA-query processing for operating channel
validation
* TX status for control port TX, for AP-side operation
* more per-STA/TID control options
* move to kHz for channels, for future S1G operation
* various other small changes

When setting the PHY cfg (CQ cmd 0x0601), if the firmware responds
with an EMODE error, software will ignore the error as it simply
means that manageability (ex: BMC) is in control of the link and that
the new setting may not be applied.

Currently when a VSI is built (i.e. reset, set channels, etc.)
the coalesce settings will be preserved in most cases. However, when the
number of q_vectors are increased the settings for the new q_vectors
will be set to the driver defaults of AIM on, Rx/Tx ITR 50, and INTRL 0.
This is causing issues with how the ethtool layer gets the current
coalesce settings since it only uses q_vector 0. So, assume that the user
set the coalesce settings globally (i.e. ethtool -C eth0) and use q_vector
0's settings for all of the new q_vectors.

Commit ceb2f00707f9 ("ice: Use pci_get_dsn()") changed the code to
use a new function to get the Device Serial Number. It also changed
the case of the filename for loading a package on a specific NIC
from lowercase to uppercase. Change the filename back to
lowercase since that is what we specified.
