Module Name:    src
Committed By:   maxv
Date:           Sat Jul  9 07:25:00 UTC 2016

Modified Files:
        src/sys/kern: subr_kobj.c subr_kobj_vfs.c
        src/sys/sys: kobj_impl.h

Log Message:
When loading a module from VFS and from the bootloader, the kernel packs
up the module segments into one big RWX chunk. Split this chunk into two
different text and data+bss+rodata chunks. The latter is made non-
executable. This also provides some kind of ASLR, since the chunks are
not necessarily contiguous.
