2bc4d06a48 Add empty definition of visit_pte_range_safe() 
This is for linking only. visit_pte_range_safe() is required only
for memdump, as far as i can tell. Since memdump is disabled anyway
I think it's ok to leave this function empty for now.

3bf77446cc mcreboot-smp-x86.sh: add extra_kopts param 
This lets one specify arbitrary kernel parameters, instead of manually
fiddling with the script.
Could ultimately replace params like -t (turbo) and -d (dump_level) that
do not have any side effect (logmode starts a userland daemon)

217dd9c1e5 x86 set_signal: panic if interrupt came from kernel 
This makes debugging errors e.g. FPE from kernel much easier,
we really shouldn't be taking a user level coredump blaming user
in that case anyway

b962da700b do_signal: ignore SIGWINCH 
McKernel would terminate() running program on terminal resizing
It actually looks like there is nothing for us to do when we
get that anyway (tested with `dialog`)
