Alan added a CONFIG options for FORCED_DEBUG slab debugging, but there
is one minor problem with FORCED_DEBUG: FORCED_DEBUG disables
HW_CACHEALIGN, and several drivers assume that HW_CACHEALIGN implies a
certain alignment (iirc usb/uhci.c assumes 16-byte alignment)

I've attached a patch that fixes the explicit alignment control in
kmem_cache_create().

The parameter 'offset' [the minimum offset to be used for cache
coloring] actually is the guaranteed alignment, except that the
implementation was broken. I've fixed the implementation and renamed
'offset' to 'align'.

Patch against 2.4.2-ac6
