From dce80a56268fffd6b5ea57b3f6ba3d027a68f05e Mon Sep 17 00:00:00 2001 From: Feng Tang Date: Wed, 26 May 2010 11:28:08 +0800 Subject: SFI: add sysfs interface for SFI tables. Analogous to ACPI's /sys/firmware/acpi/tables/... create /sys/firmware/sfi/tables/ The tables are primariy for the kernel, but sometimes it is useful for user-space to be able to read them.
