Description: x86_64: userspace address leak

Notes:
 bwh> This depends on fixes to FPU state management that have not been
 bwh> applied to 2.6.32.y.  In order to fix it, we would need to either
 bwh> pick only commit b3b0870ef3ff ("i387: do not preload FPU state at
 bwh> task switch time") which will hurt FP performance, or backport a
 bwh> large number of changes.  I did prepare a backport but don't feel
 bwh> confident enough to use it.
