ACPI: Change acpi_evaluate_integer to support 64-bit on 32-bit kernels
As of version 2.0, ACPI can return 64-bit integers. The current acpi_evaluate_integer only supports 64-bit integers on 64-bit platforms. Change the argument to take a pointer to an acpi_integer so we support 64-bit integers on all platforms. lenb: replaced use of "acpi_integer" with "unsigned long long" lenb: fixed bug in acpi_thermal_trips_update() Signed-off-by: Matthew Wilcox <willy@linux.intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
