As you can see from the comment in asm-alpha/cache.h, something
broke in networking when this was increased to 64. Someone ought
to investigate this...

No it's not. We only want to force alignment on global varaiables.
Putting the alignment on the spinlock wastes *lots* of space when
spinlocks are put into structures. Consider such infrequently used
items as inodes and sockets.
