This is the initial value. It is usually clamped to 25% of all
memory (for direct mapping) or 25% of kernel memory depending on
the machine. However, some systems (arm and i386) limit it further.

#ifndef NMBCLUSTERS_MAX
#define NMBCLUSTERS_MAX (0x2000000 / MCLBYTES)  /* Limit to 64MB for clusters */
#endif

The value is probably wrong as the comment and the commit message
talk about a 64MB limit but the value corresponds to 32MB.
