Fix some problems with the SPARSE_MAPPING option in the kernel linker.
- Ensure that the end of the mapping passed to vm_page_wire() is
page-aligned. vm_page_wire() expects this.
- Wire pages before reading data into them.
- Apply protections specified in the segment descriptor using
vm_map_protect() once relocation processing is done.
- On amd64, ensure that we load KLDs above KERNBASE, since they
are compiled with the "kernel" memory model by default.
