Subject: parisc: Mark lock_aligned variables 16-byte aligned on SMP
From: Helge Deller <deller@xxxxxx>
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.
