Just in case this list is alive...

I think I've broken the hppa port (== __MACHINE_STACK_GROWS_UP), for
the last half day or so. Could anyone test if kernel boots with
src/sys/kern/kern_exec.c Rev. 1.186?

Thanks.

Latest HEAD doesn't boot

That's not good.

Probably 1.383 works, 1.384 doesn't?

init: copying out path `/sbin/init' 11
pid 1 (init) trap #6
pid 1 (init) backtrace, starting with fp 0xb0001080
sys/kern/kern_exec.c revision 1.387

Actually, they both start init ok.

I think I've restored the original behavior (stack pointer) and now
hp700 boots again.

According to old comments, SP used to points to the top (lowest) of
argc/argv/env/aux/strings, not the bottom (highest). It'd be
interesting to run a very old userland (ld.so) on a new kernel...
