Use the observation that the initial status check for
ACPI_BUS_TYPE_PROCESSOR objects can be carried out in the same way
as for ACPI_BUS_TYPE_DEVICE objects and it is not necessary to fail
acpi_add_single_object() if acpi_bus_get_status_handle() returns an
error for a processor (its status can be set to 0 instead) to
simplify acpi_add_single_object().
Accordingly, drop the "sta" argument from acpi_init_device_object()
as it can always set the initial status to ACPI_STA_DEFAULT and let
its caller correct that later on.

Move the initial status check for ACPI_BUS_TYPE_PROCESSOR objects
into acpi_add_single_object() so it is not necessary to pass the
"sta" argument to it, get rid of that argument from there and update
the callers of that function accordingly.
No intentional functional impact.

There is only one caller of acpi_bus_type_and_status() which is
acpi_bus_check_add(), so fold the former into the latter and use
the observation that the initial status of the device is
ACPI_STA_DEFAULT in all cases except for ACPI_BUS_TYPE_PROCESSOR
to simplify the code.

When CONFIG_ARM_QCOM_SPM_CPUIDLE is y and CONFIG_MMU is not set,
compiling errors are encountered as follows:
drivers/cpuidle/cpuidle-qcom-spm.o: In function `spm_dev_probe':
cpuidle-qcom-spm.c:(.text+0x140): undefined reference to `cpu_resume_arm'
cpuidle-qcom-spm.c:(.text+0x148): undefined reference to `cpu_resume_arm'
Note that cpu_resume_arm is defined when MMU is set. So, add dependency
on MMU in ARM_QCOM_SPM_CPUIDLE configuration.

Trusted Foundation firmware doesn't implement the do_idle call and in
this case suspending should fall back to the common suspend path. In order
to fix this issue we will unconditionally set the NOFLUSH_L2 mode via
firmware call, which is a NO-OP on Tegra30/124, and then proceed to the
C7 idling, like it was done by the older Tegra114 cpuidle driver.

Starting with Windows 8, Windows no longer uses the ACPI-video interface
for backlight control by default. Instead backlight control is left up
to the GPU drivers and these are typically directly accessing the GPU
for this instead of going through ACPI.
This means that the ACPI video interface is no longer being tested by
many vendors, which leads to false-positive /sys/class/backlight entries
on devices which don't have a backlight at all such as desktops or
top-set boxes. These false-positives causes desktop environments to show
a non functional brightness slider in various places.
Checking the LCD flag greatly reduces the amount of false-positives,
so commit 5928c281524f ("ACPI / video: Default lcd_only to true on
Win8-ready and newer machines") enabled the checking of this flag
by default on all win8 BIOS-es. But this let to regressions on some
models, so the check was made stricter adding a DMI chassis-type check
to only enable the LCD flag checking on desktop/server chassis.
Unfortunately the chassis-type reported in the DMI strings is not always
reliable. One class of devices where this is a problem is Intel Bay Trail-T
based top-set boxes / mini PCs / HDMI sticks. These are based on reference
designs which were targetets and the reference design BIOS code
is often used without changing the chassis-type to something more
appropriate.
There are many, many Bay Trail-T based devices affected by this, so DMI
quirking our way out of this is a bad idea. This patch takes a different
approach, Bay Trail-T (unlike regular Bay Trail) is an ACPI-reduced-hw
platform and ACPI-reduced-hw platforms generally don't have
an embedded-controller and thus will use a native (GPU specific) backlight
interface. This patch enables Checking the LCD flag by default on
ACPI-reduced-hw platforms with a win8 BIOS independent of the reported
chassis-type, fixing the false positive /sys/class/backlight entries
on these devices.
Note in hindsight I should have never added the DMI chassis-type check
when the enabling of LCD flag checking on Windows 8 BIOS-es let to some
regressions. Instead I should have added DMI quirks for the (presumably
few) models where the LCD flag check let to issues. But I'm afraid that
it is too late to change this now, changing this now will likely lead to
a bunch of regressions.
This patch was tested on a Mele PCG03 mini PC.

CONFIG_ARM64_VHE was introduced with ARMv8.1 (some 7 years ago),
and has been enabled by default for almost all that time.
Given that newer systems that are VHE capable are finally becoming
available, and that some systems are even incapable of not running VHE,
drop the configuration altogether.
Anyone willing to stick to non-VHE on VHE hardware for obscure
reasons should use the 'kvm-arm.mode=nvhe' command-line option.

It seems that the CPUs part of the SoC known as Apple M1 have the
terrible habit of being stuck with HCR_EL2.E2H==1, in violation
of the architecture.
Try and work around this deplorable state of affairs by detecting
the stuck bit early and short-circuit the nVHE dance. Additional
filtering code ensures that attempts at switching to nVHE from
the command-line are also ignored.
It is still unknown whether there are many more such nuggets
to be found...

Some CPUs are broken enough that some overrides need to be rejected
at the earliest opportunity. In some cases, that's right at cpu
feature override time.

Currently we require that software at a higher exception level initialise
all registers at the exception level the kernel will be entered prior to
starting the kernel in order to ensure that there is nothing uninitialised
which could result in an UNKNOWN state while running the kernel. The
expectation is that the software running at the highest exception levels
will be tightly coupled to the system and can ensure that all available
features are appropriately initialised and that the kernel can initialise
anything else.
There is a gap here in the case where new registers are added to lower
exception levels that require initialisation but the kernel does not yet
understand them. Extend the requirement to also include exception levels
below the one where the kernel is entered to cover this.

"1. Update devfreq core
- Register devfreq as a cooling device when adding devfreq device,
basically if the flag of devfreq device is set as cooling device.
- Add missing unlock opeation in devfreq_add_device
- Use the next frequency as resume_freq instead of previous frequency
when using opp-suspend property
- Check whether .get_dev_status in struct devfreq_dev_profile is
implemented or not by devfreq driver before calling .get_dev_status
function.
2. Update devfreq drivers
- Use dev_err_probe to simplify the error handling on rk3399_dmc.c
- Remove unused .get_dev_status function on imx8m-ddrc.c because
imx8m_ddrc_get_dev_status has not returend the any current status
of the device.
- Remove unneeded of_match_ptr() from imx-bus.c and imx8m-ddrc.ca
- Add missing phandle informatioon and replace undefined variable
with integer value for rk3399_dmc.txt devicetree binding document.
3. Fix minor issues
- Fix the wrong set_freq path of userspace governor in
drivers/devfreq/Kconfig.
- Remove the invalid description from .get_target_freq in struct
devfreq_dev_profile."

In ice_suspend(), ice_clear_interrupt_scheme() is called, and then
irq_free_descs() will be eventually called to free irq and its descriptor.
In ice_resume(), ice_init_interrupt_scheme() is called to allocate new
irqs. However, in ice_rebuild_arfs(), struct irq_glue and struct cpu_rmap
maybe cannot be freed, if the irqs that released in ice_suspend() were
reassigned to other devices, which makes irq descriptor's affinity_notify
lost.
So call ice_free_cpu_rx_rmap() before ice_clear_interrupt_scheme(), which
can make sure all irq_glue and cpu_rmap can be correctly released before
corresponding irq and descriptor are released.
Fix the following memory leak.

Remove error handling through pointers. Instead use plain int
to return value from i40e_run_xdp(...).
Previously:
- sparse errors were produced during compilation:
i40e_txrx.c:2338 i40e_run_xdp() error: (-2147483647) too low for ERR_PTR
i40e_txrx.c:2558 i40e_clean_rx_irq() error: 'skb' dereferencing possible ERR_PTR()
- sk_buff* was used to return value, but it has never had valid
pointer to sk_buff. Returned value was always int handled as
a pointer.

mte.S by commit 2cb34276427a ("arm64: kasan: simplify and inline

2cb34276427a did not delete the old function prototypes in mte.h.

When we enable SVE usage in userspace after taking a SVE access trap we
need to ensure that the portions of the register state that are not
shared with the FPSIMD registers are zeroed. Currently we do this by
forcing the FPSIMD registers to be saved to the task struct and converting
them there. This is wasteful in the common case where the task state is
loaded into the registers and we will immediately return to userspace
since we can initialise the SVE state directly in registers instead of
accessing multiple copies of the register state in memory.
Instead in that common case do the conversion in the registers and
update the task metadata so that we can return to userspace without
spilling the register state to memory unless there is some other reason
to do so.

Fixes for omaps for v5.12-rc cycle
Fix swapped mmc device order also for omap3 that got changed with the
recent PROBE_PREFER_ASYNCHRONOUS changes. While eventually the aliases
should be board specific, all the mmc device instances are all there in
the SoC, and we do probe them by default so that PM runtime can idle the
devices if left enabled from the bootloader.
Also included are two compiler warning fixes.

git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux
Pull close_range() fix from Christian Brauner:
"Syzbot reported a bug in close_range.
Debugging this showed we didn't recalculate the current maximum fd
number for CLOSE_RANGE_UNSHARE | CLOSE_RANGE_CLOEXEC after we unshared
the file descriptors table. As a result, max_fd could exceed the
current fdtable maximum causing us to set excessive bits.
As a concrete example, let's say the user requested everything from fd
4 to ~0UL to be closed and their current fdtable size is 256 with
their highest open fd being 4. With CLOSE_RANGE_UNSHARE the caller
will end up with a new fdtable which has room for 64 file descriptors
since that is the lowest fdtable size we accept. But now max_fd will
still point to 255 and needs to be adjusted. Fix this by retrieving
the correct maximum fd value in __range_cloexec().
I've carried this fix for a little while but since there was no
linux-next release over easter I waited until now.
With this change close_range() can be further simplified but imho we
are in no hurry to do that and so I'll defer this for the 5.13 merge
window"
