Comment (by kallisti5):
Looking at the logs and the mmu code,
{{{
src/system/boot/arch/arm/arch_mmu.cpp
init_page_directory()...
// ****
// 80000 - d0000 here....
// *****
// map ourselfs first... just to make sure
mmu_map_identity((addr_t)&_start, (addr_t)&_end, ARM_MMU_L2_FLAG_C);
// ****
// 100000 - 300000 here....
// *****
// map our page directory region (TODO should not be identity mapped)
mmu_map_identity((addr_t)sPageDirectory, sPageTableRegionEnd,
ARM_MMU_L2_FLAG_C);
}}}
So what is attempting to use the 300000+?
