[Qemu-devel] [PATCH 15/19] pc: acpi: bump DSDT revision compliance to v2

[Igor Mammedov]

it turns on 64-bit integer handling in OSPM, which we could use
for writing simpler/smaller AML code.
Tested with Windows XP and Windows Server 2008, Linux:
 * XP doesn't care about revision and continues to use 32 integers
   and boots just fine with this change.
 * WS 2008 and Linux - support rev2 and use 64-bit integers
