|
|    x86: check dsdt before find oem table for es7000, v2
|
|    v2: use __acpi_unmap_table()
that patch need:
	x86: use early_ioremap in __acpi_map_table
	x86: always explicitly map acpi memory
	acpi: remove final __acpi_map_table mapping before setting acpi_gbl_permanent_mmap
	acpi/x86: introduce __apci_map_table, v4
submitted to the ACPI tree but not upstream yet.
fix it until those patches applied, need to revert this one
