--------------------------------

commit b28fc0d8739c03e7b6c44914a9d00d4c6dddc0ea upstream.

On parisc we need 16-byte alignment for variables which are used for
locking. Mark the __lock_aligned attribute acordingly so that the
.data..lock_aligned section will get that alignment in the generated
object files.
