rtw_hw_queue_mapping() and ac_to_hwq[] hold values of type enum
rtw_tx_queue_type. Change their types to reflect this to make it easier
to understand this part of the code.
While here, also change the array to be static const as it is not
supposed to be modified at runtime.

Add compatibility with WPS by passing on WPS enrollee information in
probe requests. Ignore other IEs supplied in the scan request. This also
has the added benefit of restoring compatibility with newer
wpa_supplicant versions that always add scan IEs. Previously, with
max_scan_ie_len set to 0, scans would always fail.

The existing code only converts the first IE to a TLV, but it returns a
value that takes the length of all IEs into account. When there is more
than one IE (which happens with modern wpa_supplicant versions for
example), the returned length is too long and extra junk TLVs get sent
to the firmware, resulting in an association failure.
Fix this by finding the first RSN or WPA IE and only adding that. This
has the extra benefit of working properly if the RSN/WPA IE isn't the
first one in the IE buffer.
While we're at it, clean up the code to use the available structs like
the other lbs_add_* functions instead of directly manipulating the TLV
buffer.

If the cpuidle driver provides the target residency and exit latency in

More Qualcomm ARM64 DT updates for 6.3
The new Qualcomm QDU1000 and QRU1000 platforms, and the IDP device on
these are introduced. New support for a couple of USB modem sticks from
THWC are introduced, so is support for Xiaomi Mi Pad 5 Pro and the Pro
SKU of the Herobrine device.
The Core Bus Fabric (CBF) is introduced on MSM8996. Interconnect paths
for UFS are also described.
A few fixes related to the power-grid of herobrine, on SC7280, are
introduced.
QFPROM is introduced on IPQ8074 and Interconnect providers are added for
SDM670.
On SDM845 the duplicated wcd9340 audio coded description is moved from
devices to a common file, audio devices are added to the OnePlus 6 and
6T.
On SM6115 debug UART, SMP2P, watchdog nodes are introduced, and the
platform is switched to use #address/size-cells of 2, in line with most
other platforms.
Camera control interface and clock controllers are added for SM6350, and
the CCI interface is enabled on the Fairphone FP4.
On SM8350 the interconnect reference of SDHCI controller is corrected,
DSI1 PHY clocks are properly described as sources for the Display clock
controller and DSI1 is wired up to the display controller.
The firmware paths are corrected for the Sony Xperia Nagara platform.
The GPR bus, audio servic3es and LPASS pinctrl nodes are added for the
SM8550 platform. Additionally a few small typos/errors are corrected.
gpio-ranges are corrected across MSM8953, SM6115 and SC8280XP and a
range of DT validation issues are corrected.

Where <trusted key op> is one of:

Because the pages can't be from highmem get_kernel_pages() boils down to
a get_page() call.
Remove the get_kernel_pages() call and open code the get_page().
In case a highmem page does slip through warn on once for a kmap'ed

When the 'ti,gpio-config' property is not defined, the
device_property_count_u32() will return an error, rather than zero.
The current check, only handles a return value of zero, which assumes that
the property is defined and has nothing defined.
This change extends the check to also check for an error case (most likely
to be hit by the case that the 'ti,gpio-config' is not defined).
In case that the 'ti,gpio-config' and the returned 'gpio_count' is not
correct, there is a 'if (gpio_count != ADCX140_NUM_GPIO_CFGS)' check, a few
lines lower that will return -EINVAL.
This means that someone tried to define 'ti,gpio-config', but with the
wrong number of GPIOs.

vdpasim_queue_ready calls vringh_init_iotlb, which resets split indexes.
But it can be called after setting a ring base with
vdpasim_set_vq_state.
Fix it by stashing them. They're still resetted in vdpasim_vq_reset.
This was discovered and tested live migrating the vdpa_sim_net device.

Add CLOCK_EVT_FEAT_DYNIRQ to allow the IRQ could be runtime set affinity
to the cores that needs wake up, otherwise saying core0 has to send
IPI to wakeup core1. With CLOCK_EVT_FEAT_DYNIRQ set, when broadcast
timer could wake up the cores, IPI is not needed.
After enabling this feature, especially the scene where cpuidle is
enabled can benefit.

The comment in the remove callback suggests that the driver is not
supposed to be unbound. However returning an error code in the remove
callback doesn't accomplish that. Instead set the suppress_bind_attrs
property (which makes it impossible to unbind the driver via sysfs).
The only remaining way to unbind a em_sti device would be module
unloading, but that doesn't apply here, as the driver cannot be built as
a module.
Also drop the useless remove callback.

A static key is used to select between SBI and Sstc timer usage in
riscv_clock_next_event(), but currently the direction is resolved
after cpuhp_setup_state() is called (which sets the next event). The
first event will therefore fall through the sbi_set_timer() path; this
breaks Sstc-only systems. So, apply the jump patching before first
use.

Having a clocksource_arch_init() callback always sets vdso_clock_mode to
VDSO_CLOCKMODE_ARCHTIMER if GENERIC_GETTIMEOFDAY is enabled, this is
required for the riscv-timer.
This works for platforms where just riscv-timer clocksource is present.
On platforms where other clock sources are available we want them to
register with vdso_clock_mode set to VDSO_CLOCKMODE_NONE.
On the Renesas RZ/Five SoC OSTM block can be used as clocksource [0], to
avoid multiple clock sources being registered as VDSO_CLOCKMODE_ARCHTIMER
move setting of vdso_clock_mode in the riscv-timer driver instead of doing
this in clocksource_arch_init() callback as done similarly for ARM/64
architecture.

Since commit 0166dc11be91 ("of: make CONFIG_OF user selectable"), it
is possible to test-build any driver which depends on OF on any
architecture by explicitly selecting OF. Therefore depending on
COMPILE_TEST as an alternative is no longer needed.

RISC-V provides an architectural clock source via the time CSR. This
clock source exposes a 64-bit counter synchronized across all CPUs.
Because it is accessed using a CSR, it is much more efficient to read
than MMIO clock sources. For example, on the Allwinner D1, reading the
sun4i timer in a loop takes 131 cycles/iteration, while reading the
RISC-V time CSR takes only 5 cycles/iteration.
Adjust the RISC-V clock source rating so it is preferred over the
various platform-specific MMIO clock sources.

Similarly to commit 022eb8ae8b5e ("ARM: 8938/1: kernel: initialize
broadcast hrtimer based clock event device"), RISC-V needs to initiate
hrtimer based broadcast clock event device before C3STOP can be used.
Otherwise, the introduction of C3STOP for the RISC-V arch timer in
commit 232ccac1bd9b ("clocksource/drivers/riscv: Events are stopped
during CPU suspend") leaves us without any broadcast timer registered.
This prevents the kernel from entering oneshot mode, which breaks timer
behaviour, for example clock_nanosleep().
A test app that sleeps each cpu for 6, 5, 4, 3 ms respectively, HZ=250
& C3STOP enabled, the sleep times are rounded up to the next jiffy:

With the tokens for all implemented RTAS functions now available via
rtas_function_token(), which is optimal and safe for arbitrary
contexts, there is no need to use rtas_token() or cache its result.
Most conversions are trivial, but a few are worth describing in more
detail:
* Error injection token comparisons for lockdown purposes are
consolidated into a simple predicate: token_is_restricted_errinjct().
* A couple of special cases in block_rtas_call() do not use
rtas_token() but perform string comparisons against names in the
function table. These are converted to compare against token values
instead, which is logically equivalent but less expensive.
* The lookup for the ibm,os-term token can be deferred until needed,
instead of caching it at boot to avoid device tree traversal during
panic.
* Since rtas_function_token() accesses a read-only data structure
without taking any locks, xmon's lookup of set-indicator can be
performed as needed instead of cached at startup.

Users of rtas_token() supply a string argument that can't be validated
at build time. A typo or misspelling has to be caught by inspection or
by observing wrong behavior at runtime.
Since the core RTAS code now has consolidated the names of all
possible RTAS functions and mapped them to their tokens, token lookup
can be implemented using symbolic constants to index a static array.
So introduce rtas_function_token(), a replacement API which does that,
along with a rtas_service_present()-equivalent helper,
rtas_function_implemented(). Callers supply an opaque predefined
function handle which is used internally to index the function
table. Typos or other inappropriate arguments yield build errors, and
the function handle is a type that can't be easily confused with RTAS
tokens or other integer types.

/proc/powerpc/lparcfg derives the LPAR name and SPLPAR characteristics
it reports using bare calls to the RTAS ibm,get-system-parameter
function. Convert these to the higher-level papr_sysparm API, which
handles the tedious details.
While the SPLPAR string parsing code could stand to be updated, that
should be done in a separate change. It is minimally modified here to
reduce the risk of changing behavior.
