*** This bug is a security vulnerability ***

Public security bug reported:

A flaw was found in the linux kernel which could cause a kernel panic
when restoring machine specific registers on ppc platform.  Incorrect
transactional memory state registers could inadvertently change the call
path on return from userspace and cause the kernel to enter an unknown
state in the transactional memory handling code and panic in a BUG_ON()
defensively.
