3 # kernel gets loaded at 0x00f00000 by the loader, but runs at virtual address
4 # 0xc0f00000. RAM starts at 0. We put the pagetable at a reasonable place
5 # in memory, but may need to bounce it higher if there's a problem with this.
6 # We could paper over this by loading the kernel at 0xc0000000 virtual, but
7 # that leads to other complications, so we'll just reclaim the lower region of
8 # ram after we're loaded. Put the page tables for startup at 1MB.
