This is v7 of a driver for the Corsair Commander Pro.
It provides sysfs attributes for:
- Reading fan speed
- Reading temp sensors
- Reading voltage values
- Writing pwm and reading last written pwm
- Reading fan and temp connection status

It is an usb driver, so it needs to be ignored by usbhid.
The Corsair Commander Pro is a fan controller and provides
no means for user interaction.
The two device numbers are there, because there is a slightly
different version of the same device. (Only difference
seem to be in some presets.)

Squashed:
 hwmon: (corsair-cpro) add fan_target

 This adds fan_target entries to the corsair-cpro driver.
 Reading the attribute from the device does not seem possible, so
 it returns the last set value (same as pwm).

 send_usb_cmd now has one more argument, which is needed for the
 fan_target command.

Using s64 type, instead of long type, for internal calculations and for
the sysfs interface.

This allows 64-bit values to appear correctly on 32-bit kernels.
As wattage is reported in microwatts, monitoring a power supply over
2KW requires this.

Although it may seem unlikely to run a 32-bit kernel on such a large
machine, enterprise servers often include a BMC, and the BMC might be
running a 32-bit kernel.

Pull timer fixes from Thomas Gleixner:
 "Two fixes for the timer wheel:

   - A timer which is already expired at enqueue time can set the
     base->next_expiry value backwards. As a consequence base->clk can
     be set back as well. This can lead to timers expiring early. Add a
     sanity check to prevent this.

   - When a timer is queued with an expiry time beyond the wheel
     capacity then it should be queued in the bucket of the last wheel
     level which is expiring last.

     The code adjusted the expiry time to the maximum wheel capacity,
     which is only correct when the wheel clock is 0. Aside of that the
     check whether the delta is larger than wheel capacity does not
     check the delta, it checks the expiry value itself. As a result
     timers can expire at random.

     Fix this by checking the right variable and adjust expiry time so
     it becomes base->clock plus capacity which places it into the
     outmost bucket in the last wheel level"

Pull irq fixes from Thomas Gleixner:
 "Two fixes for the interrupt subsystem:

   - Make the handling of the firmware node consistent and do not free
     the node after the domain has been created successfully. The core
     code stores a pointer to it which can lead to a use after free or
     double free.

     This used to "work" because the pointer was not stored when the
     initial code was written, but at some point later it was required
     to store it. Of course nobody noticed that the existing users break
     that way.

   - Handle affinity setting on inactive interrupts correctly when
     hierarchical irq domains are enabled.

     When interrupts are inactive with the modern hierarchical irqdomain
     design, the interrupt chips are not necessarily in a state where
     affinity changes can be handled. The legacy irq chip design allowed
     this because interrupts are immediately fully initialized at
     allocation time. X86 has a hacky workaround for this, but other
     implementations do not.

     This cased malfunction on GIC-V3. Instead of playing whack a mole
     to find all affected drivers, change the core code to store the
     requested affinity setting and then establish it when the interrupt
     is allocated, which makes the X86 hack go away"

It has been observed that Toshiba DT01ACA family drives have
WRITE FPDMA QUEUED command timeouts and sometimes just freeze until
power-cycled under heavy write loads when their temperature is getting
polled in SCT mode. The SMART mode seems to be fine, though.

Let's make sure we don't use SCT mode for these drives then.

While only the 3 TB model was actually caught exhibiting the problem let's
play safe here to avoid data corruption and extend the ban to the whole
family.

tss_invalidate_io_bitmap() wasn't wired up properly through the pvop
machinery, so the TSS and Xen's io bitmap would get out of sync
whenever disabling a valid io bitmap.

Add a new pvop for tss_invalidate_io_bitmap() to fix it.

This is XSA-329.

 "A batch of arm64 fixes.

  Although the diffstat is a bit larger than we'd usually have at this
  stage, a decent amount of it is the addition of comments describing
  our syscall tracing behaviour, and also a sweep across all the modular
  arm64 PMU drivers to make them rebust against unloading and unbinding.

  There are a couple of minor things kicking around at the moment (CPU
  errata and module PLTs for very large modules), but I'm not expecting
  any significant changes now for us in 5.8.

   - Fix kernel text addresses for relocatable images booting using EFI
     and with KASLR disabled so that they match the vmlinux ELF binary.

   - Fix unloading and unbinding of PMU driver modules.

   - Fix generic mmiowb() when writeX() is called from preemptible
     context (reported by the riscv folks).

   - Fix ptrace hardware single-step interactions with signal handlers,
     system calls and reverse debugging.

   - Fix reporting of 64-bit x0 register for 32-bit tasks via
     'perf_regs'.

   - Add comments describing syscall entry/exit tracing ABI"

Setting interrupt affinity on inactive interrupts is inconsistent when
hierarchical irq domains are enabled. The core code should just store the
affinity and not call into the irq chip driver for inactive interrupts
because the chip drivers may not be in a state to handle such requests.

X86 has a hacky workaround for that but all other irq chips have not which
causes problems e.g. on GIC V3 ITS.

Instead of adding more ugly hacks all over the place, solve the problem in
the core code. If the affinity is set on an inactive interrupt then:

    - Store it in the irq descriptors affinity mask
    - Update the effective affinity to reflect that so user space has
      a consistent view
    - Don't call into the irq chip driver

This is the core equivalent of the X86 workaround and works correctly
because the affinity setting is established in the irq chip when the
interrupt is activated later on.

Note, that this is only effective when hierarchical irq domains are enabled
by the architecture. Doing it unconditionally would break legacy irq chip
implementations.

For hierarchial irq domains this works correctly as none of the drivers can
have a dependency on affinity setting in inactive state by design.

Remove the X86 workaround as it is not longer required.

When an expiration delta falls into the last level of the wheel, that delta
has be compared against the maximum possible delay and reduced to fit in if
necessary.

However instead of comparing the delta against the maximum, the code
compares the actual expiry against the maximum. Then instead of fixing the
delta to fit in, it sets the maximum delta as the expiry value.

This can result in various undesired outcomes, the worst possible one
being a timer expiring 15 days ahead to fire immediately.
