Thanks - I wasn't aware of any issues there, but I'll see if I can dig a bit 
further
into this. From a quick glance I suspect it's most likely the commits 
immediately
below the one above to mark the memory used by -kernel and -initrd in use, but 
these
were added to make sure that we didn't accidentally claim from the memory 
containing
the kernel/initrd...


ATB,

Mark.
