There shouldn't be any 31 bit code around anymore that matters.
Remove the compat layer support required to run 31 bit code.
Reason for removal is code simplification and reduced test effort.
Note that this comes without any deprecation warnings added to config
options, or kernel messages, since most likely those would be ignored
anyway.
If it turns out there is still a reason to keep the compat layer this
can be reverted at any time in the future.

All system call wrappers should match the sys_call_ptr_t type. This is not
the case for system calls without parameters. Add the missing pt_regs
parameter there too.
Note: this is currently not a problem, since the parameter is unused.
However it prevents to create a correctly typed system call table in
C. With the current assembler implementation this works because of

On Tegra410, Compute and System GPIOs have same port names. This

at the same time. This is exposed to allow subsystems that already

Add a virtual GPIO proxy driver which arbitrates access to a single
shared GPIO by multiple users. It works together with the core shared
GPIO support from GPIOLIB and functions by acquiring a reference to a
shared GPIO descriptor exposed by gpiolib-shared and making sure that
the state of the GPIO stays consistent.
In general: if there's only one user at the moment: allow it to do
anything as if this was a normal GPIO (in essence: just propagate calls
to the underlying real hardware driver). If there are more users: don't
allow to change the direction set by the initial user, allow to change
configuration options but warn about possible conflicts and finally:
treat the output-high value as a reference counted, logical "GPIO
enabled" setting, meaning: the GPIO value is set to high when the first
user requests it to be high and back to low once the last user stops
"voting" for high.

This module scans the device tree (for now only OF nodes are supported
but care is taken to make other fwnode implementations easy to
integrate) and determines which GPIO lines are shared by multiple users.
It stores that information in memory. When the GPIO chip exposing shared
lines is registered, the shared GPIO descriptors it exposes are marked
as shared and virtual "proxy" devices that mediate access to the shared
lines are created. When a consumer of a shared GPIO looks it up, its
fwnode lookup is redirected to a just-in-time machine lookup that points
to this proxy device.
This code can be compiled out on platforms which don't use shared GPIOs.

strcpy() is deprecated; inline the read-only string instead. Fix the
function comment and use bool instead of int while we're at it.

Examples (i.e. doctests) may want to show public items such as structs,
thus the `unreachable_pub` warning is not very helpful.
Thus allow it for all doctests.
In addition, remove it from the existing `expect`s we have in a couple
doctests.
