Please use savedefconfig to place the changes in the correct location
Also indicate changes if any in vmlinux in commit message.
A bootlog indicating functionality in diffstat is also additional good
thing to do.

Just to clarify the request, use "make savedefconfig" to generate a
defconfig, then based on that put _only_ the relevant changes in the
commit.

Nishanth, what are you asking for here? Just a mentioning if this has
any impact to vmlinux (or is isolated to the modules selected), or are
you asking for anything specific?

Yup, thanks for clarifying.

In this case, just ensure to state that vmlinux size has'nt
changed, in case where we see a =y, we should indicate via
./scripts/bloat-o-meter change that is introduced and if yes, we
should explain why this is fundamental to system boot.
Why is this necessary? This is to prevent product specific
configurations (such as early display banner, chime etc) from creeping
and increasing vmlinux size which has an impact for all ARM SoCs.

Sounds very reasonable, I'll make sure to ask for such motivations in
the defconfig changes that I pick up through the Qualcomm tree as well.
