The entry16 and entry16_debug functions need to compute appropriate 16-bit segments before dropping to real mode. Each is intended to use its own entry address as the segment base. However, both were using the entry address of entry16_debug, causing the code-segment reload to branch to the wrong place in the non-debug case. This bug was only visible when running kexec with --real-mode and without --debug.
