uref->field_index, uref->usage_index, finfo.field_index and cinfo.index can be
indirectly controlled by user-space, hence leading to a potential exploitation
of the Spectre variant 1 vulnerability.

This issue was detected with the help of Smatch:

drivers/hid/usbhid/hiddev.c:473 hiddev_ioctl_usage() warn: potential spectre issue 'report->field' (local cap)
drivers/hid/usbhid/hiddev.c:477 hiddev_ioctl_usage() warn: potential spectre issue 'field->usage' (local cap)

drivers/hid/usbhid/hiddev.c:801 hiddev_ioctl() warn: potential spectre issue 'hid->collection' (local cap)

Fix this by sanitizing such structure fields before using them to index
report->field, field->usage and hid->collection

Notice that given that speculation windows are large, the policy is
to kill the speculation on the first load and not worry if it can be
completed with a dependent load/store [1].

If pinctrl nodes for 100/200MHz are missing, the controller should
not select any mode which need signal frequencies 100MHz or higher.
To prevent such speed modes the driver currently uses the quirk flag
SDHCI_QUIRK2_NO_1_8_V. This works nicely for SD cards since 1.8V
signaling is required for all faster modes and slower modes use 3.3V
signaling only.

However, there are eMMC modes which use 1.8V signaling and run below
100MHz, e.g. DDR52 at 1.8V. With using SDHCI_QUIRK2_NO_1_8_V this
mode is prevented. When using a fixed 1.8V regulator as vqmmc-supply
the stack has no valid mode to use. In this tenuous situation the
kernel continuously prints voltage switching errors:
  mmc1: Switching to 3.3V signalling voltage failed

Avoid using SDHCI_QUIRK2_NO_1_8_V and prevent faster modes by
altering the SDHCI capability register. With that the stack is able
to select 1.8V modes even if no faster pinctrl states are available:
  # cat /sys/kernel/debug/mmc1/ios
  ...
  timing spec:    8 (mmc DDR52)
  signal voltage: 1 (1.80 V)
  ...

After commit 18996f2d (ACPICA: Events: Stop unconditionally
clearing ACPI IRQs during suspend/resume) the status of ACPI events
is not cleared any more when entering the ACPI S5 system state (power
off) which causes some systems to power up immediately after turing
off power in certain situations.

That is a functional regression, so address it by making the code
clear the status of all ACPI events again when entering S5 (for
system-wide suspend or hibernation the clearing of the status of all
events is not desirable, as it might cause the kernel to miss wakeup
events sometimes).

 - The hopefully final fix for the reported race problems in

   the race condition is hit as the remote CPU is idle. Plug it by
   checking the condition again when holding run queue lock.

 - Fix a bug in the utilization estimation of a run queue which causes
   the estimation to be 0 when a run queue is throttled.

 - Advance the global expiration of the period timer when the timer is
   restarted after a idle period. Otherwise the expiry time is stale and
   the timer fires prematurely.

 - Cure the drift between the bandwidth timer and the runqueue
   accounting, which leads to bogus throttling of runqueues

   will observe the correct number of running RT tasks and not a stale
   one.

In general, accessing userspace memory beyond the length of the supplied
buffer in VFS read/write handlers can lead to both kernel memory corruption
(via kernel_read()/kernel_write(), which can e.g. be triggered via
sys_splice()) and privilege escalation inside userspace.

Fix it by using simple_read_from_buffer() instead of custom logic.

Corsair Strafe appears to suffer from the same issues
as the Corsair Strafe RGB.
Apply the same quirks (control message delay and init delay)
that the RGB version has to 1b1c:1b15.

With these quirks in place the keyboard works correctly upon
booting the system, and no longer requires reattaching the device.

This parameter introduced several years ago in the XHCI host controller
driver was somehow left undocumented. Add a few lines in the kernel
parameters text.
