3573b8649e Guard call to gencore and freecore 
The gencore() and freecore() code in gencore.c is guarded by
POSTK_DEBUG_ARCH_DEP_18, so the call to these functions should
also be guarded, otherwise linking fails.

0a22320a3c Don't allocate memory for 0-page-sized requests 
Previously the allocator would return all availble memory for a
request of 0 pages. This is rather counter-intuitive and left no
memory for subsequent allocations.

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)

c3dfb1663d page_fault_handler: do not try to fault addresses < 4k 
There is no good reason to map these low addresses (userspace could with
mmap fixed, but that is grounds for many exploits...);

the main advantage however is if we do a null deref or close to (0->foo)
within a pagefault we will get a panic stack instead of getting a hang
because we cannot get some locks.

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

d4cd756a91 x86/cpu.c: unhandled page fault: print pre-fault stack

suggested invocation of addr2line to pretty-print the result.

b894619d1b Speed up parallel builds 
- make should be $(MAKE)
 - add + in front of rules spawning long-lasted make process in a
subshell. (This would not be needed with $(MAKE) -C .. target, but our
makefiles do not handle that because they use $(PWD))
 - split the main 'all' rule as all 4 targets are independant
 - fix dependencies where appropriate for parallelism

Extra, not speed-related changes:
 - remove some double-colon for targets as they do not need it

This cuts build time from 5s to 1.5s on a laptop with -j4, and more
importantly from 85s to 35s on a KNL node.
As a bonus, the fixed dependencies removes the need to clean before
rebuilding all the time. Probably.

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`)
