I tried this and got a parse error. So I assumed perhaps I
needed to upgrade to the latest C compiler to be able
to handle the assignment of a inline static initializer:
#define CPU_MASK_NONE { {[0 ... CPU_ARRAY_SIZE-1] = 0UL} }
I was disappointed that using gcc 3.3 didn't fix the problem:

------------------------------------------------------------------------------
I'll settle for Matt Mackall <mpm@selenic.com> fix for now:
+#define apm_save_cpus() (current->cpus_allowed)
I wonder why other, like Thomas Schlichter <schlicht@uni-mannheim.de>,
had no problem with the CPU_MASK_NONE fix.
I tried adding the #include <linux/cpumask.h> that Marc-Christian
Petersen <m.c.p@wolk-project.de> sugested but it didn't help. Looks
like Jan De Luyck <lkml@kcore.org> had a similar result.
