One of the items on the agenda for this release cycle is fixing the
min stack size macros & runtime limits to be correct per-arch. Some
archs require significantly more than the current values, but I'm not
sure what their needs are. I can do the research, but if anyone has
time to help with this, it would be a nice non-coding way to
contribute.
Basically what I need to know is: for each arch, what is the max size
the kernel allows itself to use for storing saved register state
(sigcontext/mcontext plus any external data these structures point
into)?
For x86_64 and any other arch with redzone, this has to include the
size of the redzone too.
