Liang Yi 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.

Requires explicit arch path name in the include directive.

The config scripts was also updated to reflect this change.

Yonghua Huang 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.

Yonghua Huang ea44bb6c4d hv: wrap function to check software SRAM support
Below boolean function are defined in this patch:
 - is_software_sram_enabled() to check if SW SRAM
   feature is enabled or not.
 - set global variable 'is_sw_sram_initialized'
   to file static.

Li Fei1 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.

Yonghua Huang c9ca23d268 hv: refine RTCM initialization code
- RTCM is initialized in hypervisor only
   if RTCM binaries are detected.
 - Remove address space of RTCM binary from
   Software SRAM region.
 - Refine parse_rtct() function, validity of
   ACPI RTCT table shall be checked by caller.

Yonghua Huang a6e666dbe7 hv: remove hardcoding of SW SRAM HPA base
Physical address to SW SRAM region maybe different
 on different platforms, this hardcoded address may
 result in address mismatch for SW SRAM operations.

 This patch removes above hardcoded address and uses
 the physical address parsed from native RTCT.
