83d56e0edb vm: add necessary dummy APIs
get_vm_from_vmid,is_paused_vm and is_poweroff_vm should be common APIs.
But now doesn't implement them as common for not introduce more VM related
data structure and APIs.

037c479221 hv: ipi: drop arch_ prefix from IPI functions
Since there is no common IPI abstraction, the arch_ prefix is redundant.
This patch renames the functions as follows:
    - arch_send_dest_ipi_mask -> send_dest_ipi_mask
    - arch_send_single_ipi   -> send_single_ipi

Rename send_single_ipi() and send_dest_ipi_mask() to
arch_send_single_ipi() and arch_send_dest_ipi_mask() in x86, to make the
naming consistent with the RISC-V implementation and reflect that these
functions are arch-specific.

1c7e1a192b hv: refactor hypervisor image size helper function
The hypervisor image size is determined at link time, but now it is
calculated and stored in a global variable during mmu initialization,
and the helper function reads from that variable. Change to calculate
it inside helper function to avoid inconsistency.

8b16be9185 Remove "All rights reserved" string headers
Many of the license and Intel copyright headers include the "All rights
reserved" string. It is not relevant in the context of the BSD-3-Clause
license that the code is released under. This patch removes those strings
throughout the code (hypervisor, devicemodel and misc).

fa6b55db68 hv: tee: Handling x86_tee secure interrupts corner cases
Previous upstreamed patches handles the secure/non-secure interrupts in
handle_x86_tee_int. However there is a corner case in which there might
be unhandled secure interrupts (in a very short time window) when TEE
yields vCPU. For this case we always make sure that no secure interrupts
are pending in TEE's vlapic before scheduling REE.

Also in previous patches, if non-secure interrupt comes when TEE is
handling its secure interrupts, hypervisor injects a predefined vector
into TEE's vlapic. TEE does not consume this vector in secure interrupt
handling routine so it stays in vIRR, but it should be cleared because the
actual interrupt will be consumed in REE after VM Entry.

v3:
    Fix comments on interrupt priority

v2:
    Add comments explaining the priority of secure/non-secure interrupts

fd7ab300a8 hv: tee: Rename TEE_NOTIFICATION_VECTOR to TEE_FIXED_NONSECURE_VECTOR
The TEE_NOTIFICATION_VECTOR can sometimes be confused with TEE's PI
notification vector. So rename it to TEE_FIXED_NONSECURE_VECTOR for
better readability.

No logic change.

v3:
Add more comments in commit message.

e97b171ca2 hv: tee: x86_tee interrupt support
Secure interrupt (interrupt belongs to TEE) comes
when TEE vcpu is running, the interrupt will be
injected to TEE directly. But when REE vcpu is running
at that time, we need to switch to TEE for handling.

Non-Secure interrupt (interrupt belongs to REE) comes
when REE vcpu is running, the interrupt will be injected
to REE directly. But when TEE vcpu is running at that time,
we need to inject a predefined vector to TEE for notification
and continue to switch back to TEE for running.

To sum up, when secure interrupt comes, switch to TEE
immediately regardless of whether REE is running or not;
when non-Secure interrupt comes and TEE is running,
just notify the TEE and keep it running, TEE will switch
to REE on its own initiative after completing its work.

3c9c41b656 hv: tee: add x86_tee hypercall interfaces
This patch adds the x86_tee hypercall interfaces.

- HC_TEE_VCPU_BOOT_DONE

This hypercall is used to notify the hypervisor that the TEE VCPU Boot
is done, so that we can sleep the corresponding TEE VCPU. REE will be
started at the last time this hypercall is called by TEE.

- HC_SWITCH_EE

For REE VM, it uses this hypercall to request TEE service.

For TEE VM, it uses this hypercall to switch back to REE
when it completes the REE service.

f3792a74a3 hv: tee: add TEE VM memmap support
TEE is a secure VM which has its own partitioned resources while
REE is a normal VM which owns the rest of platform resources.
The TEE, as a secure world, it can see the memory of the REE
VM, also known as normal world, but not the other way around.
But please note, TEE and REE can only see their own devices.

So this patch does the following things:

1. go through physical e820 table, to ept add all system memory entries.
2. remove hv owned memory.
