[PATCH] reduce MAX_NR_ZONES: fix MAX_NR_ZONES array initializations
Fix array initialization in lots of arches
The number of zones may now be reduced from 4 to 2 for many arches. Fix the
array initialization for the zones array for all architectures so that it is
not initializing a fixed number of elements.
