With CONFIG_CRASH_DUMP_MEMDEV=y in the kernel config this results in the dump_overlay compile error, with that disabled everything compiles fine.
If your kernel .config looks like this, it will compile fine: CONFIG_CRASH_DUMP=m CONFIG_KERNTYPES=y CONFIG_CRASH_DUMP_BLOCKDEV=m CONFIG_CRASH_DUMP_NETDEV=m # CONFIG_CRASH_DUMP_MEMDEV is not set CONFIG_CRASH_DUMP_COMPRESS_RLE=m CONFIG_CRASH_DUMP_COMPRESS_GZIP=m The upstream is looking into the MEMDEV problem, but suffice to say that you don't need it to do kernel crash dumps to a disk device (such as swap) or to a network device.
