The ACPI spec speicifies that arguments "Revision ID" and
"Function Index" to a _DSM are type "Integer." Type Integers
are 64 bit quantities.
The function evaluate_dsm specifies these types as simple "int"
which are 32 bits. Correct type passed to acpi_evaluate_dsm
and its callers and derived callers to pass correct type.
acpi_check_dsm and acpi_evaluate_dsm_typed had similar issue
and were corrected as well.
