- * Note on how mapped kernels work: the text and data section is
- * compiled at cksseg segment (LOADADDR = 0xc001c000), and the
- * init/setup/data section gets a 16M virtual address bump in the
- * ld.script file (so that tlblo0 and tlblo1 maps the sections).
- * The vmlinux.64 section addresses are put in the xkseg range
- * using the change-addresses makefile option. Use elfdump -of
- * on IRIX to see where the sections go. The Origin loader loads
- * the two sections contiguously in physical memory. The loader
- * sets the entry point into kernel_entry using a xkphys address,
- * but instead of using 0xa800000001160000, it uses the address
- * 0xa800000000160000, which is where it physically loaded that
- * code. So no jumps can be done before we have switched to using
- * cksseg addresses.
