Subject: [PATCH 236/482] * grub-core/commands/acpihalt.c (skip_ext_op):
Add support for skipping Event, Device, Processor, PowerRes,
ThermalZone, and BankField extended opcodes. (get_sleep_type):
Add minimal scope handling (just enough to handle setting the scope to
the root path). (grub_acpi_halt): Parse any SSDTs as well as the
DSDT. * include/grub/acpi.h: Add enumeration values for Event, Device,
Processor, PowerRes, ThermalZone, and BankField extended opcodes.
