- * In TILE Linux each set of four of these uses another 16MB chunk of
- * address space, given 64 tiles and 64KB pages, so we only enable
- * ones that are required by the kernel configuration.
+ * In 32-bit TILE Linux we have to balance the desire to have a lot of
+ * nested atomic mappings with the fact that large page sizes and many
+ * processors chew up address space quickly.  In a typical
+ * 64-processor, 64KB-page layout build, making KM_TYPE_NR one larger
+ * adds 4MB of required address-space.  For now we leave KM_TYPE_NR
+ * set to depth 8.
