+Subject: [PATCH] Using DMI firmware in sysfs if exists
+
+On arm64 system scanning /dev/mem for SMBIOS tables might fail and
+stopped with SIGBUS. Kernel version > 4.2 provides DMI tables in
+/sys/firmware/dmi/tables and it is much safer for ipmi-locate to
+read. If it exists, reading from it instead of /dev/mem fix
+ipmi-locate crash on several arm64 system.
+
+Unfortunately mmap() does not work on DMI tables so also fallback to
+read if mmap() failed.
