[PATCH 0/3] Transactional memory fixes

[Paul Mackerras]

This series of patches fixes a couple of cases where bugs in the
handling of FP/VMX/VSX state around transactions can lead to
corruption of the FP/VMX/VSX state visible to user processes.  The
bugs were found basically by inspection but then verified by writing
small test programs that provoke the bugs.
