AKASHI Takahiro 254a41c0ba arm64: hibernate: preserve kdump image around hibernation ... Since arch_kexec_protect_crashkres() removes a mapping for crash dump kernel image, the loaded data won't be preserved around hibernation. In this patch, helper functions, crash_prepare_suspend()/ crash_post_resume(), are additionally called before/after hibernation so that the relevant memory segments will be mapped again and preserved just as the others are. In addition, to minimize the size of hibernation image, crash_is_nosave() is added to pfn_is_nosave() in order to recognize only the pages that hold loaded crash dump kernel image as saveable. Hibernation excludes any pages that are marked as Reserved and yet "nosave."
