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).

1a6ead9af5 hv: update RTCT ACPI table detecting
Signature of RTCT ACPI table maybe "PTCT"(v1) or "RTCT"(v2).
 and the MAGIC number in CRL header is also changed from "PTCM"
 to "RTCM".

 This patch refine the code to detect RTCT table for both
 v1 and v2.

688a41c290 hv: mod: do not use explicit arch name when including headers
Instead of "#include <x86/foo.h>", use "#include <asm/foo.h>".

In other words, we are adopting the same practice in Linux kernel.

ae43b2a847 hv: disable host MONITOR-WAIT support when SW SRAM is enabled
Per-core software SRAM L2 cache may be flushed by 'mwait'
extension instruction, which guest VM may execute to enter
core deep sleep. Such kind of flushing is not expected when
software SRAM is enabled for RTVM.

Hypervisor disables MONITOR-WAIT support on both hypervisor
and VMs sides to protect above software SRAM from being flushed.

This patch disable hypervisor(host) MONITOR-WAIT support and refine
software sram initializaion flow.

94a980c923 hv: hypercall: prevent sos can touch hv/pre-launched VM resource
Current implementation, SOS may allocate the memory region belonging to
hypervisor/pre-launched VM to a post-launched VM. Because it only verifies
the start address rather than the entire memory region.

This patch verifies the validity of the entire memory region before
allocating to a post-launched VM so that the specified memory can only
be allocated to a post-launched VM if the entire memory region is mapped
in SOS’s EPT.
