Last change on this file since 031e264 was 031e264, checked in by Jakub Jermar <jakub@…>, 20 years ago

Fix cpu_init(): frame_alloc() can return 0 as the valid address of block of frames. Do not signal error.

sparc64 work.
Reorganize kernel vs. userspace memory layout.
Add panic_printf().
Turn dummy() into nop rather than into infinite loop.
