[ 26/56] firmware: Add missing attributes to EFI variable attribute print out from sysfs
From: Greg Kroah-Hartman
Date: Thu Oct 04 2012 - 18:14:07 EST
3.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Khalid Aziz <khalid.aziz@xxxxxx>
commit 7083909023bbe29b3176e92d2d089def1aa7aa1e upstream.
Some of the EFI variable attributes are missing from print out from
/sys/firmware/efi/vars/*/attributes. This patch adds those in. It also
updates code to use pre-defined constants for masking current value
of attributes.
