[PATCH] Mantaining turnstile aligned to 128 bytes in i386 CPUs

[Attilio Rao]

Hi,
Intel documentation points out that having a 128-bytes aligned
syncronizing primitive  (which fits in a cache line) will minimize the
traffic for cache bus, so this patch implements an alignment for i386
on turnstiles.

Any comments, feedbacks?

Attilio

PS: Using __aligned on MI code is usually a bad practice, but please
note that the case !__i386__ is not affected (as you can see in the
patch)
