    4444#  Regarding the boot and kernel vsegs mapping :
    45 #  - We use one big physical page (2 Mbytes) for the preloader and the four
    46 #    boot vsegs, all allocated in cluster[0,0].
    47 #  - We use one big page per cluster for the replicated kernel code vsegs.
    48 #  - We use one big page in cluster[0][0] for the kernel data vseg.
    49 #  - We use one big page per cluster for the distributed kernel heap vsegs.
    50 #  - We use one big page per cluster for the distributed ptab vsegs.
    51 #  - We use small physical pages (4 Kbytes) per cluster for the schedulers.
    52 #  - We use one big page for each external peripheral in IO cluster,
    53 #  - We use one small page per cluster for each internal peripheral.
     45#  - We use one big physical page (2 Mbytes) for the preloader,
     46#    the 4 boot vsegs are packed in one BPP allocated in cluster[0,0].
     47#  - We use one BPP per cluster for the replicated kernel code vsegs.
     48#  - We use one BPP in cluster[0][0] for the kernel data vseg.
     49#  - We use two BPP per cluster for the distributed kernel heap vsegs.
     50#  - We use one BPP per cluster for the distributed ptab vsegs.
     51#  - We use two SPP per cluster for each schedulers.
     52#  - We use one PBB for each external peripheral in IO cluster,
     53#  - We use one SPP per cluster for each internal peripheral.
