The Bluetooth interface of the 2nd-gen Intuos Pro batches together four
independent "frames" of finger data into a single report. Each frame
is essentially equivalent to a single USB report, with the up-to-10
fingers worth of information being spread across two frames. At the
moment the driver only calls `input_sync` after processing all four
frames have been processed, which can result in the driver sending
multiple updates for a single slot within the same SYN_REPORT. This
can confuse userspace, so modify the driver to sync more often if
necessary (i.e., after reporting the state of all fingers).

The button numbering of the 2nd-gen Intuos Pro is not consistent between
the USB and Bluetooth interfaces. Over USB, the HID_GENERIC codepath
enumerates the eight ExpressKeys first (BTN_0 - BTN_7) followed by the
center modeswitch button (BTN_8). The Bluetooth codepath, however, has
the center modeswitch button as BTN_0 and the the eight ExpressKeys as
BTN_1 - BTN_8. To ensure userspace button mappings do not change
depending on how the tablet is connected, modify the Bluetooth codepath
to report buttons in the same order as USB.
To ensure the mode switch LED continues to toggle in response to the
mode switch button, the `wacom_is_led_toggled` function also requires
a small update.

The Bluetooth reports from the 2nd-gen Intuos Pro have separate bits for
indicating if the tip or eraser is in contact with the tablet. At the
moment, only the tip contact bit controls the state of the BTN_TOUCH
event. This prevents the eraser from working as expected. This commit
changes the driver to send BTN_TOUCH whenever either the tip or eraser
contact bit is set.

If the tool spends some time in prox before entering range, a series of
events (e.g. ABS_DISTANCE, MSC_SERIAL) can be sent before we or userspace
have any clue about the pen whose data is being reported. We need to hold
off on reporting anything until the pen has entered range. Since we still
want to report events that occur "in prox" after the pen has *left* range
we use 'wacom-tool[0]' as the indicator that the pen did at one point
enter range and provide us/userspace with tool type and serial number
information.

The serial number and tool type information that is reported by the tablet
while a pen is merely "in prox" instead of fully "in range" can be stale
and cause us to report incorrect tool information. Serial number, tool
type, and other information is only valid once the pen comes fully in range
so we should be careful to not use this information until that point.
In particular, this issue may cause the driver to incorectly report
BTN_TOOL_RUBBER after switching from the eraser tool back to the pen.

The touchpad on the cover keyboard for the Acer Switch 3 and 5 does not
work as-is under Linux. Both devices have the same usb id for the cover
keyboard.
The kernel correctly assigns the hid-rmi driver to the device using usbhid
for transport.
Any attempts of hid-rmi to talk to the device using hid_hw_output_report
fail however as usbhid does not have a working urbout due to the lack of
any out endpoints.
Looking through Wireshark usbmon recordings from the Windows Synaptics
driver for this computer running inside of QEMU shows that it should be
using SET_REPORT requests instead.
This replaces the hid_hw_output_report in hid-rmi with a
hid_hw_raw_request for this device, which is at least enough to enable
the kernel to get working multi-touch input.

this one:
lib/ubsan.c warning: conflicting types for built-in function
‘__ubsan_handle_negate_overflow’; expected ‘void(void *, void *)’ [-Wbuiltin-declaration-mismatch]
The kernel's declarations of __ubsan_handle_*() often uses 'unsigned

hence the mismatch.
Fix this by using 'void *' to match GCC's declarations.

New race in x86_pmu_stop() was introduced by replacing the
atomic __test_and_clear_bit() of cpuc->active_mask by separate
test_bit() and __clear_bit() calls in the following commit:
3966c3feca3f ("x86/perf/amd: Remove need to check "running" bit in NMI handler")
The race causes panic for PEBS events with enabled callchains:

Allow the boot CPU/CPU0 to be nohz_full. Have the boot CPU take the
do_timer duty during boot until a housekeeping CPU can take over.
This is supported when CONFIG_PM_SLEEP_SMP is not configured, or when
it is configured and the arch allows suspend on non-zero CPUs.
nohz_full has been trialed at a large supercomputer site and found to
significantly reduce jitter. In order to deploy it in production, they
need CPU0 to be nohz_full because their job control system requires
the application CPUs to start from 0, and the housekeeping CPUs are
placed higher. An equivalent job scheduling that uses CPU0 for
housekeeping could be achieved by modifying their system, but it is
preferable if nohz_full can support their environment without
modification.

This patch provides an arch option, ARCH_SUSPEND_NONZERO_CPU, to
opt-in to allowing suspend to occur on one of the housekeeping CPUs
rather than hardcoded CPU0.
This will allow CPU0 to be a nohz_full CPU with a later change.
It may be possible for platforms with hardware/firmware restrictions
on suspend/wake effectively support this by handing off the final
stage to CPU0 when kernel housekeeping is no longer required. Another
option is to make housekeeping / nohz_full mask dynamic at runtime,
but the complexity could not be justified at this time.

This recent commit:
5768402fd9c6e87 ("perf/ring_buffer: Use high order allocations for AUX buffers optimistically")
overlooked the fact that the previous one page granularity of the AUX buffer
provided an implicit double buffering capability to the PMU driver, which
went away when the entire buffer became one high-order page.
Always make the full-trace mode AUX allocation at least two-part to preserve
the previous behavior and allow the implicit double buffering to continue.

Commit 307244452d3d ("crypto: caam - generate hash keys in-place")
fixed ahash implementation in caam/jr driver such that user-provided key
buffer is not DMA mapped, since it's not guaranteed to be DMAable.
Apply a similar fix for caam/qi2 driver.

Mutex is badly used between threaded irq and driver.
This mutex must be removed as the framework must ensure
that requests must be serialized to avoid issue. Rework
req to avoid crash during finalize by fixing the NULL
pointer issue.
