 #  Regarding the boot and kernel vsegs mapping :
-#  - We use one big physical page (2 Mbytes) for the preloader and the four
-#    boot vsegs, all allocated in cluster[0,0].
-#  - We use one big page per cluster for the replicated kernel code vsegs.
-#  - We use one big page in cluster[0][0] for the kernel data vseg.
-#  - We use one big page per cluster for the distributed kernel heap vsegs.
-#  - We use one big page per cluster for the distributed ptab vsegs.
-#  - We use small physical pages (4 Kbytes) per cluster for the schedulers.
-#  - We use one big page for each external peripheral in IO cluster,
-#  - We use one small page per cluster for each internal peripheral.
+#  - We use one big physical page (2 Mbytes) for the preloader,
