I'm working on various trivial patches (mainly whitespace and
checkpatch.pl cleanups).
I read quite some time ago that it's best to md5sum the vmlinux file
before and after these trivial patches are applied (to ensure that no
executable code has changed, modules on a binary level are identical, etc).
So far, I have no problems producing identical .o and .ko files with my
trivial patches. My problem lies in the resulting vmlinux and vmlinux.o
file, though.
I know the files are different due to date/timestamping the kernel, but
I'm not sure where this happens (and how I can prevent it). Are there
pieces of code and/or Makefile that I can comment out so that the
resulting vmlinux file isn't timestamped (and thus would be an exactly
identical before and after). I know it can be done... I've done it
before (years ago), but seem to have forgotten the trick.
Thanks for the help!
