2013-01-21taint: add explicit flag to show whether lock dep is still OK.Rusty Russell

2011-05-29ACPI: Split out custom_method functionality into an own driverThomas Renninger
With /sys/kernel/debug/acpi/custom_method root can write to arbitrary memory and increase his priveleges, even if these are restricted. -> Make this an own debug .config option and warn about the security issue in the config description. -> Still keep acpi/debugfs.c which now only creates an empty /sys/kernel/debug/acpi directory. There might be other users of it later. Signed-off-by: Thomas Renninger <trenn@suse.de> Acked-by: Rafael J.
