Bug#703574: efivars can turn some Samsung systems into bricks

[Ben Hutchings <ben@decadent.org.uk>]

Package: src:linux
Version: 3.2.39-2
Severity: critical
Tags: upstream fixed-upstream patch

EFI can store named variables in persistant storage (i.e. flash),
which is compacted at boot.  On some Samsung systems (and maybe
others), compaction fails and the system will not boot if the
variable space is more than 50% full.

The workaround for this is:

    efi: be more paranoid about available space when creating variables

which I backported into 3.2.41.

Ben.
