The HID descriptor for the 2nd-gen Intuos Pro large (PTH-860) contains a typo which defines an incorrect logical maximum Y value. This causes a small portion of the bottom of the tablet to become unusable (both because the area is below the "bottom" of the tablet and because 'wacom_wac_event' ignores out-of-range values). It also results in a skewed aspect ratio. To fix this, we add a quirk to 'wacom_usage_mapping' which overwrites the data with the correct value.

Current ISH driver only registers suspend/resume PM callbacks which don't support hibernation (suspend to disk). Basically after hiberation, the ISH can't resume properly and user may not see sensor events (for example: screen rotation may not work). User will not see a crash or panic or anything except the following message in log: hid-sensor-hub 001F:8086:22D8.0001: timeout waiting for response from ISHTP device So this patch adds support for S4/hiberbation to ISH by using the SIMPLE_DEV_PM_OPS() MACRO instead of struct dev_pm_ops directly. The suspend and resume functions will now be used for both suspend to RAM and hibernation. If power management is disabled, SIMPLE_DEV_PM_OPS will do nothing, the suspend and resume related functions won't be used, so mark them as __maybe_unused to clarify that this is the intended behavior, and remove #ifdefs for power management.

When creating the low-level hidraw device, the reference to steam_device was stored using hid_set_drvdata(). But this value is not guaranteed to be kept when set before calling probe. If this pointer is reset, it crashes when opening the emulated hidraw device. It looks like hid_set_drvdata() is for users "avobe" this hid_device, while hid_device.driver_data it for users "below" this one. In this case, we are creating a virtual hidraw device, so we must use hid_device.driver_data.

Due to the autofs4 module using a file system type name of autofs different from the module containing directory name autoload did not function properly. To work around this kernel configurations have often elected to build the module into the kernel. This can result in selinux policies that prohibit autoloading of the autofs module which need to be changed. Add a comment about this to "possible changes" section of the autofs4 module help.

WHen registering a new binfmt_misc handler, it is possible to overflow the offset to get a negative value, which might crash the system, or possibly leak kernel data.

percpu_ida() decouples disabling interrupts from the locking operations. This breaks some assumptions if the locking operations are replaced like they are under -RT. The same locking can be achieved by avoiding local_irq_save() and using spin_lock_irqsave() instead. percpu_ida_alloc() gains one more preemption point because after unlocking the fastpath and before the pool lock is acquired, the interrupts are briefly enabled.
