5bffde62a1 net: hns3: modify the IRQ name of TQP vector
When rename the net devices, the IRQ number can not be
fetched by the net device name, because the driver request
the IRQ resources only when the vector resource changed, and
the rename operation did not change the vector resources,
so the IRQ name keeps the previous net device name.
So this patch modifies the name of the TQP IRQ as
"pci driver name"-"pci name"-"TxRx"-"index".

08a100689d net: hns3: re-organize vector handle
To prevent loss user's IRQ affinity configuration when DOWN,
this patch moves out release/request operation of the vector
handle from net DOWN/UP, just do it when vector resource changes.

698a89541c net: hns3: add trace event support for HNS3 driver
This adds trace support for HNS3 driver. It also declares
some events which could be used to trace the events when a
TX/RX BD is processed, and other events which are related to
the processing of sk_buff, such as TSO, GRO.

The complaint above occurred because the memory region pointed by attrbuf

regulator: samsung: Rename Samsung to lowercase
Fix up inconsistent usage of upper and lowercase letters in "Samsung"
name.

"SAMSUNG" is not an abbreviation but a regular trademarked name.
Therefore it should be written with lowercase letters starting with
capital letter.

Although advertisement materials usually use uppercase "SAMSUNG", the
lowercase version is used in all legal aspects (e.g. on Wikipedia and in
privacy/legal statements on
https://www.samsung.com/semiconductor/privacy-global/).

ASoC: Intel: sof_rt5682: Ignore the speaker amp when there isn't one.
Some members of the Google_Hatch family include a rt5682 jack codec, but
no speaker amplifier. This uses the same driver (sof_rt5682) as a
combination of rt5682 jack codec and max98357a speaker amplifier. Within
the sof_rt5682 driver, these cases are not currently distinguishable,
relying on a DMI quirk to decide the configuration. This causes an
incorrect configuration when only the rt5682 is present on a
Google_Hatch device.

For CML, the jack codec is used as the primary key when matching,
with a possible speaker amplifier described in quirk_data. The two cases
of interest are the second and third 10EC5682 entries in
snd_soc_acpi_intel_cml_machines[]. The second entry matches the
combination of rt5682 and max98357a, resulting in the quirk_data field
in the snd_soc_acpi_mach being non-null, pointing at
max98357a_spk_codecs, the snd_soc_acpi_codecs for the matched speaker
amplifier. The third entry matches just the rt5682, resulting in a null
quirk_data.

The sof_rt5682 driver's DMI data matching identifies that a speaker
amplifier is present for all Google_Hatch family devices. Detect cases
where there is no speaker amplifier by checking for a null quirk_data in
the snd_soc_acpi_mach and remove the speaker amplifier bit in that case.

5f70bde26a selftests: fix build behaviour on targets' failures
Currently, when some of the KSFT subsystems fails to build, the toplevel
KSFT Makefile just keeps carrying on with the build process.

This behaviour is expected and desirable especially in the context of a CI
system running KSelfTest, since it is not always easy to guarantee that the
most recent and esoteric dependencies are respected across all KSFT TARGETS
in a timely manner.

Unfortunately, as of now, this holds true only if the very last of the
built subsystems could have been successfully compiled: if the last of
those subsystem instead failed to build, such failure is taken as the whole
outcome of the Makefile target and the complete build/install process halts
even though many other preceding subsytems were in fact already built
successfully.

Fix the KSFT Makefile behaviour related to all/install targets in order
to fail as a whole only when the all/install targets have failed for all
of the requested TARGETS, while succeeding when at least one of TARGETS
has been successfully built.

"earlycon" no need to specify the value string since it uses
stdout-path parameters. However when earlycon and normal console
are not using the same uart port, we need specify value string
to earlycon, this is what we need to do when support dual linux
using jailhouse hypervisor. The 2nd linux will use the uart
of the 1st linux as earlycon.

earlycon=lpuart32,mmio32,0x5a060010,115200 not work for i.MX8QXP.
It is because lpuart32_early_console_setup not support little endian.

Since the original code is to support UPIO_MEM32BE, so if not
UPIO_MEM32, we still take it as UPIO_MEM32BE

loopback mode.

f3974413cf tty: serial: qcom_geni_serial: Wakeup IRQ cleanup
This patch is the continuation of below mentioned commits which adds wakeup
feature over the UART RX line.
1)commit 3e4aaea7a0 ("tty: serial: qcom_geni_serial: IRQ cleanup")[v2]
2)commit 8b7103f319 ("tty: serial: qcom_geni_serial: Wakeup over UART
  RX")[v2]

The following cleanup is done based on upstream comment received on
subsequent versions of the above-mentioned commits to simplifying the code.
 - Use devm_kasprintf API in place of scnprintf.
 - Use dev_pm_set_dedicated_wake_irq API that will take care of
   requesting and attaching wakeup irqs for devices. Also, it sets wakeirq
   status to WAKE_IRQ_DEDICATED_ALLOCATED as a result enabling/disabling of
   wake irq will be managed by suspend/resume framework. We can remove the
   code for enabling and disabling of wake irq from the this driver.
 - Use platform_get_irq_optional API to get optional wakeup IRQ for
   device.
 - Move ISR registration later in probe after uart port gets register with
   serial core.

b209713199 serial: samsung: Rename Exynos to lowercase
Fix up inconsistent usage of upper and lowercase letters in "Exynos"
name.

"EXYNOS" is not an abbreviation but a regular trademarked name.
Therefore it should be written with lowercase letters starting with
capital letter.

The lowercase "Exynos" name is promoted by its manufacturer Samsung
Electronics Co., Ltd., in advertisement materials and on website.

68faa679b8 chardev: Avoid potential use-after-free in 'chrdev_open()'
'chrdev_open()' calls 'cdev_get()' to obtain a reference to the
'struct cdev *' stashed in the 'i_cdev' field of the target inode
structure. If the pointer is NULL, then it is initialised lazily by
looking up the kobject in the 'cdev_map' and so the whole procedure is
protected by the 'cdev_lock' spinlock to serialise initialisation of
the shared pointer.

Unfortunately, it is possible for the initialising thread to fail *after*
installing the new pointer, for example if the subsequent '->open()' call
on the file fails. In this case, 'cdev_put()' is called, the reference
count on the kobject is dropped and, if nobody else has taken a reference,
the release function is called which finally clears 'inode->i_cdev' from
'cdev_purge()' before potentially freeing the object. The problem here
is that a racing thread can happily take the 'cdev_lock' and see the
non-NULL pointer in the inode, which can result in a refcount increment
from zero and a warning:

Since 'cdev_get()' can already fail to obtain a reference, simply move
it over to use 'kobject_get_unless_zero()' instead of 'kobject_get()',
which will cause the racing thread to return -ENXIO if the initialising
thread fails unexpectedly.

c5ee0b3104 serdev: Don't claim unsupported ACPI serial devices
Serdev sub-system claims all ACPI serial devices that are not already
initialised. As a result, no device node is created for serial ports
on certain boards such as the Apollo Lake based UP2. This has the
unintended consequence of not being able to raise the login prompt via
serial connection.

Introduce a blacklist to reject ACPI serial devices that should not be
claimed by serdev sub-system. Add the peripheral ids for Intel HS UART
to the blacklist to bring back serial port on SoCs carrying them.

The intention was to only select a higher pixel-clock rate than the
requested, if a slight overclocking would result in a rate significantly
closer to the requested rate than if the conservative lower pixel-clock
rate is selected. The fixed patch has the logic the other way around and
actually prefers the higher frequency. Fix that.

Changing pixel clock source without having this clock source enabled
will block the timing engine and the next operations after (in this case
setting ATMEL_HLCDC_CFG(5) settings in atmel_hlcdc_crtc_mode_set_nofb()
will fail). It is recomended (although in datasheet this is not present)
to actually enabled pixel clock source before doing any changes on timing
enginge (only SAM9X60 datasheet specifies that the peripheral clock and
pixel clock must be enabled before using LCD controller).

The ARMv8 64-bit architecture supports execute-only user permissions by
clearing the PTE_USER and PTE_UXN bits, practically making it a mostly
privileged mapping but from which user running at EL0 can still execute.

The downside, however, is that the kernel at EL1 inadvertently reading
such mapping would not trip over the PAN (privileged access never)
protection.

Revert the relevant bits from commit cab15ce604 ("arm64: Introduce
execute-only page access permissions") so that PROT_EXEC implies
PROT_READ (and therefore PTE_USER) until the architecture gains proper
support for execute-only user mappings.

Fixes: cab15ce604 ("arm64: Introduce execute-only page access permissions")

aa4a63dd98 tpm: Revert "tpm_tis_core: Turn on the TPM before probing IRQ's"
There has been a bunch of reports (one from kernel bugzilla linked)
reporting that when this commit is applied it causes on some machines
boot freezes.

Unfortunately hardware where this commit causes a failure is not widely
available (only one I'm aware is Lenovo T490), which means we cannot
predict yet how long it will take to properly fix tpm_tis interrupt
probing.

Thus, the least worst short term action is to revert the code to the
state before this commit. In long term we need fix the tpm_tis probing
code to work on machines that Stefan's fix was supposed to fix.
