ACPI: add boot option acpi=copy_dsdt to fix corrupt DSDT
Some BIOS on Toshiba machines corrupt the DSDT, so add a new boot option acpi=copy_dsdt to workaround it. Add warning message to ask users to use this option if corrupt DSDT detected. Also build a DMI blacklist to check it and automatically copy DSDT. https://bugzilla.kernel.org/show_bug.cgi?id=14679 Signed-off-by: Lin Ming <ming.m.lin@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
