+         This lets you select the page size of the kernel.  For best
+         performance, a page size of 16KB is recommended.  For best
+         compatibility with 32bit applications, a page size of 4KB should be
+         selected (the vast majority of 32bit binaries work perfectly fine
+         with a larger page size).
