Comment (by arvindsraj):

 In the newest version of the patch, sp points to the highest address of
 the RAM_stack specified in LOADER_MEMORYMAP.

 Also, mmu_init sets the amount of physical memory allocated to
 0(http://cgit.haiku-
 os.org/haiku/tree/src/system/boot/arch/arm/arch_mmu.cpp#n621) but the
 stack frames for start_netbsd and start_raw are using up physical memory.
 Would that be a problem?
