Some utils, like dmidecode and smbios, need to access SMBIOS entry table area in order to get information like SMBIOS version, size, etc. Currently it's done via /dev/mem. But for situation when /dev/mem usage is disabled, the utils have to use dmi sysfs instead, which doesn't represent SMBIOS entry and adds code/delay redundancy when direct access for table is needed. So this patch creates dmi/tables and adds SMBIOS entry point to allow utils in question to work correctly without /dev/mem. Also patch adds raw dmi table to simplify dmi table processing in user space, as proposed by Jean Delvare.
