Just for the heck of it, I just tried to boot a 7.99.52 kernel built
from today's sources (just a few hours old, updated on 2016-12-27 at
04:43:26 UTC). I got a uvmfault during startup, right after it set my
hostname.
The failing process was running ifconfig, and here's the backtrace

This is an automatically generated notice of a NetBSD-current/i386
build failure.
The failure occurred on babylon5.netbsd.org, a NetBSD/amd64 host,
using sources from CVS date 2016.12.26.23.39.18.
An extract from the build.sh output follows:

I think you can avoid the #ifdef in uvm_mmap.c by simply definining
the macro PAX_MPROTECT_ADJUST() to return 0 if the feature is off.
Also, it would be wiser to just add error handling to the call in
uvm_unix.c, rather then assuming it never fails. Or just remove the
call there if it's so redunda
Hi,
I have simplified the patch, changed it to return EACCES upon errors,
adapted it to -current, and tested it there (both with PAX_MPROTECT set
and not set). It is still not 100% elegant though (adds an #ifdef) so I
will welcome ideas on how to improve it some more.
