So this only happens with _fairly_ long argument lists, right? Maybe
your config has a 64kB page size, and normal programs never expand
beyond a single page?
I bet it is because of f313c51d26aa ("execve: expand new process stack
manually ahead of time"), but I don't see exactly why.
But pa-risc is the only architecture with CONFIG_STACK_GROWSUP, and
while I really thought that commit should do the exact same thing as
the old
#ifdef CONFIG_STACK_GROWSUP
special case, I must clearly have been wrong.
Would you mind just verifying that yes, that commit on mainline is
broken for you, and the previous one works?
