Replace acpi_in_resume with a more general hack to check irqs_disabled() on any kmalloc() from ACPI. While setting (system_state != SYSTEM_RUNNING) on resume seemed more general, Andrew Morton preferred this approach. http://bugzilla.kernel.org/show_bug.cgi?id=3469 Make acpi_os_allocate() into an inline function to allow /proc/slab_allocators to work. Delete some memset() that could fault on allocation failure. Signed-off-by: Len Brown <len.brown@intel.com>
