Originally init/Kconfig.gki was just excluded on 32-bit, which works
fine for allmodconfig builds, but breaks downstream boards trying to
build specific drivers modularly (in a 'mixed tree' configuration)
for 32-bit ARM with Kleaf. Replace the workaround with a new one.

This reverts commit f896efaa.

Broke building 32-bit ARM kernels with kbuild 'mixed tree' support
in Kleaf. A different workaround will be used instead.

This hook will allow to stop extra timers that is created during scheduler_tick.
The background is described as follows:
1) In some cases, we find the 4ms tick is not enough for task scheduling so we
will start a new timer in scheduler_tick to do extra task scheduling.
The hook in scheduler_tick already exists but when cpus enter idle, the timer
needs to be stopped for saving power (same logic as nohz idle).
2) We can get about 7% power saving without hurting the performance in certain
use case after enabled this feature.
3) Actually we are considering to upstream it to mainline kernel but it can
takes time to get really merged. An initial submit is preferred to get the
community noticed the potential optimized point.

Add hooks at process exiting routines so that oems
can control these procedures. One possible benifit is the peak of
system load can be shaved and load can be more smooth when a large
number of threads is killed once upon a time, while a sudden peak
of system load can probably lead to user junk issues.

QTVMs' Gunyah resources are handled partially by the VMM. The remaining
resources are handled by the kernel clients. By providing this notifier,
we allow the client drivers to add their operations for setting up the
resources they own.

Qualcomm Trusted Virtual Machine (QTVM) are VMs that are authenticated by
Qualcomm firmware before the VM starts. The firmware also defines the
VM's image layout. Additionally, each QTVM comes with a reserved VM ID.
Introduce an IOCTL to allow VMMs to configure a QTVM and this driver will
handle the setup for QTVMs.

As QTVMs use Gunyah emulated watchdog instead of vcpu_stall detector,
provide trace_hooks to manage the watchdog of the QTVM.

RM supports authentication of VMs with the assistance of the firmware.
Add an API for auth_mgr to use if the VM it manages uses the firmare for
authentication.

Add an IOCTL to choose the authentication mechanism for a Virtual Machine.
vm_mgr can setup differently authenticated VMs based on the ops setup by
the auth_mgr chosen by the VMM.

Gunyah supports Virtual Machines (VMs) with various authentication
mechanisms. Since different authentication mechanisms require distinct
operations to be performed to set up a VM, it is necessary to add ops
that can support these mechanisms.

Allow VMMs to add a binding backed by CMA. Extend the generic Gunyah
mem APIs to handle bindings backed by CMA.

Make the bindings generic so that the APIs can now handle the binding's
memory backed either by CMA memory or GUP.
