Enable support for creating irqfds which can raise an interrupt on a
Gunyah virtual machine. irqfds are exposed to userspace as a Gunyah VM
function with the name "irqfd". If the VM devicetree is not configured
to create a doorbell with the corresponding label, userspace will still
be able to assert the eventfd but no interrupt will be raised on the
guest.

Gunyah allows host virtual machines to schedule guest virtual machines
and handle their MMIO accesses. vCPUs are presented to the host as a
Gunyah resource and represented to userspace as a Gunyah VM function.
Creating the vcpu VM function will create a file descriptor that:
- can run an ioctl: GH_VCPU_RUN to schedule the guest vCPU until the
next interrupt occurs on the host or when the guest vCPU can no
longer be run.
- can be mmap'd to share a gh_vcpu_run structure which can look up the
reason why GH_VCPU_RUN returned and provide return values for MMIO
access.

Some VM functions need to acquire Gunyah resources. For instance, Gunyah
vCPUs are exposed to the host as a resource. The Gunyah vCPU function
will register a resource ticket and be able to interact with the
hypervisor once the resource ticket is filled.
Resource tickets are the mechanism for functions to acquire ownership of
Gunyah resources. Gunyah functions can be created before the VM's
resources are created and made available to Linux. A resource ticket
identifies a type of resource and a label of a resource which the ticket
holder is interested in.
Resources are created by Gunyah as configured in the VM's devicetree
configuration. Gunyah doesn't process the label and that makes it
possible for userspace to create multiple resources with the same label.
Resource ticket owners need to be prepared for populate to be called
multiple times if userspace created multiple resources with the same
label.

Introduce a framework for Gunyah userspace to install VM functions. VM
functions are optional interfaces to the virtual machine. vCPUs,
ioeventfs, and irqfds are examples of such VM functions and are
implemented in subsequent patches.
A generic framework is implemented instead of individual ioctls to
create vCPUs, irqfds, etc., in order to simplify the VM manager core
implementation and allow dynamic loading of VM function modules.

Signed-off-by: Elliot Berman <quic_eberman@quicinc.com>
When booting a Gunyah virtual machine, the host VM may gain capabilities
to interact with resources for the guest virtual machine. Examples of
such resources are vCPUs or message queues. To use those resources, we
need to translate the RM response into a gunyah_resource structure which
are useful to Linux drivers. Presently, Linux drivers need only to know
the type of resource, the capability ID, and an interrupt.
On ARM64 systems, the interrupt reported by Gunyah is the GIC interrupt
ID number and always a SPI.

- Gunyah Resource Manager uses the VM's devicetree to configure the

virtual memory can be declared via the SET_DTB_CONFIG ioctl.
- Trigger start of the virtual machine with VM_START ioctl.

[Elliot: fixup gh_vm_free flow to align with future v12 patch]
Signed-off-by: Elliot Berman <quic_eberman@quicinc.com>
Gunyah resource manager provides API to manipulate stage 2 page tables.
Manipulations are represented as a memory parcel. Memory parcels
describe a list of memory regions (intermediate physical address and
size), a list of new permissions for VMs, and the memory type (DDR or
MMIO). Memory parcels are uniquely identified by a handle allocated by
Gunyah. There are a few types of memory parcel sharing which Gunyah
supports:
- Sharing: the guest and host VM both have access
- Lending: only the guest has access; host VM loses access
- Donating: Permanently lent (not reclaimed even if guest shuts down)
Memory parcels that have been shared or lent can be reclaimed by the
host via an additional call. The reclaim operation restores the original
access the host VM had to the memory parcel and removes the access to
other VM.
One point to note that memory parcels don't describe where in the guest
VM the memory parcel should reside. The guest VM must accept the memory
parcel either explicitly via a "gh_rm_mem_accept" call (not introduced
here) or be configured to accept it automatically at boot. As the guest
VM accepts the memory parcel, it also mentions the IPA it wants to place
memory parcel.

The resource manager is a special virtual machine which is always
running on a Gunyah system. It provides APIs for creating and destroying
VMs, secure memory management, sharing/lending of memory between VMs,
and setup of inter-VM communication. Calls to the resource manager are
made via message queues.
This patch implements the basic probing and RPC mechanism to make those
API calls. Request/response calls can be made with gh_rm_call.
Drivers can also register to notifications pushed by RM via
gh_rm_register_notifier
Specific API calls that resource manager supports will be implemented in
subsequent patches.

When Linux is booted as a guest under the Gunyah hypervisor, the Gunyah
Resource Manager applies a devicetree overlay describing the virtual
platform configuration of the guest VM, such as the message queue
capability IDs for communicating with the Resource Manager. This
information is not otherwise discoverable by a VM: the Gunyah hypervisor
core does not provide a direct interface to discover capability IDs nor
a way to communicate with RM without having already known the
corresponding message queue capability ID. Add the DT bindings that
Gunyah adheres for the hypervisor node and message queues.

Non-protected mode relies on the host to restore its SVE state if
necessary. However, protected VMs shouldn't reveal any
information to the host, including whether they have potentially
dirtied the host's sve state. Therefore, save and restore the
host's sve state at hyp in protected mode.
Currently this behavior applies to protected and non-protected
VMs in protected mode. It could be optimised for non-protected
VMs by applying the same behavior as non-protected mode, which is
to inform the host that it should restore its sve state. But for
now it's kept this way to maintain the same behavior for all VMs
in protected mode.

The code for deactivating traps, to be able to update the fpsimd
registers, is the only code in this file that is n/vhe specific.
Move it to specialized functions.
This is also needed for the subsequent patch, since the logic for
deciding which traps to enable/disable will get more complex.
No functional change intended.

Subsequent patches will augment this state to allocate space for
tracking the host sve state. SVE state size is not static, and
there isn't support for dynamic per_cpu allocation in hyp.
This is done as a first step in allowing us to allocate SVE state
under the same umbrella.
