Chris von Recklinghausen 1789737ca9 PM: hibernate: x86: Use crc32 instead of md5 for hibernation e820 integrity check ... [ Upstream commit f5d1499ae2096d7ea301023c4cc54e427300eb0a ] Hibernation fails on a system in fips mode because md5 is used for the e820 integrity check and is not available. Use crc32 instead. The check is intended to detect whether the E820 memory map provided by the firmware after cold boot unexpectedly differs from the one that was in use when the hibernation image was created. In this case, the hibernation image cannot be restored, as it may cover memory regions that are no longer available to the OS. A non-cryptographic checksum such as CRC-32 is sufficient to detect such inadvertent deviations.
