unmodified_drivers: enable use of register_oldmem_pfn_is_ram() API During the investigation of very slow dump times of guest images in Amazon EC2 instance, it was discovered that the register_oldmem_pfn_is_ram() API implemented by the upstream kernel commit 997c136f518c5debd63847e78e2a8694f56dcf90: fs/proc/vmcore.c: add hook to read_from_oldmem() to check for non-ram pages was not being called. This was due to the PV driver with the call to register_oldmem_pfn_is_ram() API was not including the kernel header file that is used to communicate support of the API in the kernel. Fix the issue by including the required header file.
