Merge branch 'dmi-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jdelvare/staging
Pull DMI updates from Jean Delvare:
"The most important change is the new sysfs interface to the DMI table,
which will let user-space tools (such as dmidecode) access the table
without relying on /dev/mem"
* 'dmi-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jdelvare/staging:
firmware: dmi: struct dmi_header should be packed
firmware: dmi_scan: Coding style cleanups
Documentation: ABI: sysfs-firmware-dmi: add -entries suffix to file name
firmware: dmi_scan: add SBMIOS entry and DMI tables
firmware: dmi_scan: Trim DMI table length before exporting it
firmware: dmi_scan: Rename dmi_table to dmi_decode_table
firmware: dmi: List my quilt tree
firmware: dmi_scan: Only honor end-of-table for 64-bit tables
