Pull input fixes from Dmitry Torokhov:

 - a reworked way for handling reset delay on SMBus-connected Synaptics
   touchpads (the original one, while being correct, uncovered an old
   bug in fallback to PS/2 code that was fixed separately; the new one
   however avoids having delay in serio port "fast" resume, and instead
   has the wait in the RMI4 code)

 - a fix for potential crashes when devices with Elan controllers (and
   Synaptics) fall back to PS/2 code. Can't be hit without the original
   patch above, but still good to have it fixed

 - a couple new device IDs in xpad Xbox driver

 - another quirk for Goodix driver to deal with stuff vendors put in
   ACPI tables

 - a fix for use-after-free on disconnect for powermate driver

 - a quirk to not initialize PS/2 mouse port on Fujitsu Lifebook E5411
   laptop as it makes keyboard not usable and the device uses
   hid-over-i2c touchpad anyways

syzbot has found a use-after-free bug [1] in the powermate driver. This
happens when the device is disconnected, which leads to a memory free from
the powermate_device struct.  When an asynchronous control message
completes after the kfree and its callback is invoked, the lock does not
exist anymore and hence the bug.

Use usb_kill_urb() on pm->config to cancel any in-progress requests upon
device disconnection.

Touch controllers need some time after receiving reset command for the
firmware to finish re-initializing and be ready to respond to commands
from the host. The driver already had handling for the post-reset delay
for I2C and SPI transports, this change adds the handling to
SMBus-connected devices.

SMBus devices are peculiar because they implement legacy PS/2
compatibility mode, so reset is actually issued by psmouse driver on the
associated serio port, after which the control is passed to the RMI4
driver with SMBus companion device.

Note that originally the delay was added to psmouse driver in
92e24e0e ("Input: psmouse - add delay when deactivating for SMBus
mode"), but that resulted in an unwanted delay in "fast" reconnect
handler for the serio port, so it was decided to revert the patch and
have the delay being handled in the RMI4 driver, similar to the other
transports.

When the SMBus connection is attempted psmouse_smbus_init() sets
the fast_reconnect pointer to psmouse_smbus_reconnecti(). If SMBus
initialization fails, elantech_setup_ps2() and synaptics_init_ps2() will
fallback to PS/2 mode, replacing the psmouse private data. This can cause
issues on resume, since psmouse_smbus_reconnect() expects to find an
instance of struct psmouse_smbus_dev in psmouse->private.

The issue was uncovered when in 92e24e0e ("Input: psmouse - add
delay when deactivating for SMBus mode") psmouse_smbus_reconnect()
started attempting to use more of the data structure. The commit was
since reverted, not because it was at fault, but because there was found
a better way of doing what it was attempting to do.

Fix the problem by resetting the fast_reconnect pointer in psmouse
structure in elantech_setup_ps2() and synaptics_init_ps2() when the PS/2
mode is used.

Fixes for v6.6-rc5

- fix to not reset the PHY everytime we start link training but only
  do it if link training fails. Without this, the PLL unlocked
  interrupt fires causing "Unexpected DP AUX IRQ 0x01000000 when
  not busy" spam in the logs since last 2-3 cycles
- correct the highest bank bit to match downstream device tree for
  msm8998
- skip the video mode wait if the timing engine is not enabled. This
  was introduced after pre_enable flag for DSI video mode panels
  where we would end up waiting for the video mode done interrupt
  even before enabling timing engine causing error spam and long
  bootup times.
- check the correct return code of irq_of_parse_and_map() in DSI code
- avoid overflow issues in the dpu bandwidth calculation . This was
  exposed for high resolution displays and a critical fix to avoid
  atomic_check failure
- minor fix to add new lines in DP print messages.
- Fix to fail atomic_check() if the resolution exceeds max mdp clk.
  This leads to underflow otherwise if we try to allow that frame.

This reverts commit 92e24e0e.

While the patch itself is correct, it uncovered an issue with fallback
to PS/2 mode, where we were leaving psmouse->fast_reconnect handler set
to psmouse_smbus_reconnect(), which caused crashes.

While discussing various approaches to fix the issue it was noted that
this patch ass undesired delay in the "fast" resume path of PS/2 device,
and it would be better to actually use "reset_delay" option defined in
struct rmi_device_platform_data and have RMI code handle it for SMBus
transport as well. So this patch is being reverted to deal with crashes
and a better solution will be merged shortly.

Commit 5c0338c6 ("workqueue: restore WQ_UNBOUND/max_active==1
to be ordered") enabled implicit ordered attribute to be added to
WQ_UNBOUND workqueues with max_active of 1. This prevented the changing
of attributes to these workqueues leading to fix commit 0a94efb5
("workqueue: implicit ordered attribute should be overridable").

However, workqueue_apply_unbound_cpumask() was not updated at that time.
So sysfs changes to wq_unbound_cpumask has no effect on WQ_UNBOUND
workqueues with implicit ordered attribute. Since not all WQ_UNBOUND
workqueues are visible on sysfs, we are not able to make all the
necessary cpumask changes even if we iterates all the workqueue cpumasks
in sysfs and changing them one by one.

Fix this problem by applying the corresponding change made
to apply_workqueue_attrs_locked() in the fix commit to
workqueue_apply_unbound_cpumask().

To circumvent this, try to enable userspace access to the hardware counter
when it is selected in addition to when the event is mapped. And vice-versa
when the event is stopped/unmapped.

ftrace creates entries for each syscall in the tracefs but has failed
since commit 08d0ce30 ("riscv: Implement syscall wrappers") which
prefixes all riscv syscalls with __riscv_.

So fix this by implementing arch_syscall_match_sym_name() which allows us
to ignore this prefix.

And also ignore compat syscalls like x86/arm64 by implementing
arch_trace_is_compat_syscall().

[    0.000000] Failed to add a Crash kernel resource at 177e00000

The crashkernel memory has been allocated successfully, whereas
it failed to insert into iomem_resource. This is due to the
unique reserving logic in risc-v arch specific code, i.e.
crashk_res/crashk_low_res will be added into iomem_resource
later in init_resources(), which is not aligned with current
unified reserving logic in reserve_crashkernel_{generic,low}()
and therefore leads to the failure of crashkernel reservation.

Removing the arch specific code within #ifdef CONFIG_KEXEC_CORE
in init_resources() to fix above problem.

There are two duplicate `-O binary` flags when objcopying from vmlinux
to Image/xipImage.

RISC-V set `-O binary` flag in both OBJCOPYFLAGS in the top-level riscv
Makefile and OBJCOPYFLAGS_* in the boot/Makefile, and the objcopy cmd
in Kbuild would join them together.

The `-O binary` flag is only needed for objcopying Image, so remove the
OBJCOPYFLAGS in the top-level riscv Makefile.

Currently, the kfree() be used for pwq objects allocated with
kmem_cache_alloc() in alloc_and_link_pwqs(), this isn't wrong.
but usually, use "trace_kmem_cache_alloc/trace_kmem_cache_free"
to track memory allocation and free. this commit therefore use
kmem_cache_free() instead of kfree() in alloc_and_link_pwqs()
and also consistent with release of the pwq in rcu_free_pwq().

The alternative stack checking in get_sigframe introduced by the Vector
support is not needed and has a problem. It is not needed as we have
already validate it at the beginning of the function if we are already
on an altstack. If not, the size of an altstack is always validated at
its allocation stage with sigaltstack_size_valid().

Besides, we must only regard the size of an altstack if the handler of a
signal is registered with SA_ONSTACK. So, blindly checking overflow of
an altstack if sas_ss_size not equals to zero will check against wrong
signal handlers if only a subset of signals are registered with
SA_ONSTACK.
