I'm also worried about why there are data symbols following BSS in
our current palinux kernel...
= Though I'd worry about precisely *why* someone wants the _end symbol; whatever
= they're trying to do there's probably a better way.
Maybe there is a better way. The first reason I want to use _end
(and _edata) is to clear the kernel BSS reliably (which is working
The second reason, which doesn't currently work, is to have a symbol
pointing at the very end of kernel memory, since that is where
free memory will start.
Both these tasks are currently being done at run-time -- in one case
by parsing the SOM header and in another case by guessing about a
parameter passed in by the hpux bootloader -- neither is currently
reliable despite the considerable experimentation and
sweat others have poured into the effort. I want to avoid parsing
the SOM header and guessing about bootloaders in the future. It
would also be great to use an old, reliable, and language-system
