[GIT PULL] [lucid] mvl-dove: preserve VFP/NEON state around signal handlers

[Eric Miao]

Andy,

As Dave suggested, VFP/NEON state should be preserved around signal
handlers (as described in bug 507503). Dove is less vulnerable to this bug
as it doesn't have a NEON, but it's a better to have for the VFP as well.

Please consider pull.
