| 54 | * should not overlap that area, or the kernel will have to copy itself |
| 55 | * somewhere else before decompression. Similarly, the address of any other |
| 56 | * data passed to the kernel shouldn't overlap the start of RAM. Pushing |
| 57 | * this up to 16M allows for a sizable kernel to be decompressed below the |
