This patch has been added to the 3.18 stable tree. If you have any
objections, please let us know.
===============
[ Upstream commit 3a72494ac2a3bd229db941d51e7efe2f6ccd947b ]
The timer user status compat ioctl returned the bogus struct used for
64bit architectures instead of the 32bit one. This patch addresses
it to return the proper struct.
