efivars: Handle duplicate names from get_next_variable() (2013-03-21 12:43:46 +0000)

----------------------------------------------------------------
EFI changes for v3.9-rc3,

* A new config option and efivars module parameter have been added to allow the efivars pstore backend to be disabled as we're still seeing issues on machines despite adding heuristics to workaround known bugs. Distributions now have a way to disable EFI variable pstore code completely - from Seth Forshee.

* A couple of efivars patches to workaround quirky implementations of GetNextVariableName() which resulted in machines hanging and sysfs files being created with garbage names.

----------------------------------------------------------------
Matt Fleming (2):
efivars: explicitly calculate length of VariableName
efivars: Handle duplicate names from get_next_variable()

Seth Forshee (2):
efivars: Allow disabling use as a pstore backend
efivars: Add module parameter to disable use as a pstore backend
