[Xen-devel] [PATCH 1/3] Don't accept fuzz when patching

[Ross Lagerwall <ross.lagerwall@xxxxxxxxxx>]

When testing and applying patches, set fuzz=0 so that patches must apply
exactly.  Also set "-f" to avoid interactive questions, and reorder so
that patches are tested before the output directory is created.
