* A reasonable upper bound for the uncompressed kernel size is 32 MBytes,
* so we will reserve that amount of memory. We have no easy way to tell what
* the actuall size of code + data the uncompressed kernel will use.
* If this is insufficient, the decompressor will relocate itself out of the
* way before performing the decompression.
