Module Name:    src
Committed By:   maxv
Date:           Fri Aug 18 10:28:53 UTC 2017

Modified Files:

        src/sys/arch/i386/conf: kern.ldscript kern.ldscript.4MB

Log Message:
Fill the .text padding with 0xcc (int3), in such a way that any jump into
this area will automatically fault. The alignment within the section is
necessary, in order to fill strictly all of the padding (took me a while
to figure this out); but it does not change the kernel size.

Greatly inspired from FreeBSD, but for some reason they decided not to
apply the alignment.
