ACPICA/ACPI: Add new host interfaces for _OSI support
Adds install/remove interfaces so that the host can dynamically alter the global _OSI table. Also adds support for _OSI handlers. Additional support: new debugger command (osi), and test support in the acpiexec utility. Adds new file, utilities/utosi.c. ACPICA bugzilla 836. The Linux OSL _OSI code is also changed. acpi_osi_setup can't call acpi_install/remove_interface because ACPICA is not initialized yet at this early time. So we just save the osi string in acpi_osi_setup and will handle it later in a new function acpi_osi_setup_late. http://www.acpica.org/bugzilla/show_bug.cgi?id=836 Signed-off-by: Lin Ming <ming.m.lin@intel.com> Signed-off-by: Bob Moore <robert.moore@intel.com Signed-off-by: Len Brown <len.brown@intel.com>
