int i;
for (i = 0; i < ...; i++)

Some ACPI objects is per-vm and per-cpu specific so we need to pass
vmctx as function parameter when we write objects into DSDT table.

b50fcc022f DM: add function to write Px objects to UOS DSDT
There are 3 ACPI objects for Px: _PCT, _PPC and _PSS need to be writed
to DSDT, and the _PSS data is per-cpu specific so we need to pass the
vm id and vcpu id as parameter.

The px count and data is per-cpu so we should query them for specific

01c8053dfb DM: fix build error with gcc-8.
gcc8 showed following errors when build DM:
  error: argument to ‘sizeof’ in ‘strncpy’ call is the same
  expression as the source; did you mean to use the size of the
  destination? [-Werror=sizeof-pointer-memaccess]

It looks like wrong parameter was given to strncpy.

66ddb67bdd DM: acpi: Update the reset value of FADT to trigger cold reboot
There are bootloaders require cold reboot as ACPI reboot
instead of warm reboot.

So we set 0xE to reset value of FADT to make ACPI reboot
cold reboot.
