History
Alan Cox e58bb1c453 Changed the implementation of the primitives to guarantee atomicity 
with respect to interrupts on UP systems.  (The upgrade from gcc 2.7.x
to egcs 1.1.2 produced at least one non-atomic code sequence in
swap_pager_getpages.)

In addition, the primitives are now SMP-safe, but only on SMPs.  (For
portability between SMPs and UPs, modules are compiled with the SMP-safe
versions.)
