-	 * The taskstats structure is internally aligned on 8 byte
-	 * boundaries but the layout of the aggregrate reply, with
-	 * two NLA headers and the pid (each 4 bytes), actually
-	 * force the entire structure to be unaligned. This causes
-	 * the kernel to issue unaligned access warnings on some
-	 * architectures like ia64. Unfortunately, some software out there
-	 * doesn't properly unroll the NLA packet and assumes that the start
-	 * of the taskstats structure will always be 20 bytes from the start
-	 * of the netlink payload. Aligning the start of the taskstats
-	 * structure breaks this software, which we don't want. So, for now
-	 * the alignment only happens on architectures that require it
-	 * and those users will have to update to fixed versions of those
-	 * packages. Space is reserved in the packet only when needed.
-	 * This ifdef should be removed in several years e.g. 2012 once
-	 * we can be confident that fixed versions are installed on most
-	 * systems. We add the padding before the aggregate since the
-	 * aggregate is already a defined type.
