ACPI: tables: complete searching upon RSDP w/ bad checksum.
ACPI tables follow a tree structure in memory. The root of the tree is the RSDP (Root System Description Pointer). To find the RSDP, the OS searches for the signature "RSD PTR " in well known physical memory locations. Then the OS computes a table checksum to verify that the signature is really part of a valid table header. Some systems have a proper signature but an invalid checksum; followed elsewhere by a proper signature with valid checksum. http://bugzilla.kernel.org/show_bug.cgi?id=9444 The Linux RSDP scanning code bailed out on those systems and as a result they booted with ACPI disabled. Fix this by deleting the Linux RSDP scanning code and plugging in the ACPICA RSDP scanning code. Signed-off-by: Len Brown <len.brown@intel.com>
