You are just repeating what the OP already knows ;). But what is the
reason for e.g. the version mismatch?

Probably the info is provided by this message.

"dpkg-buildpackage: error: debian/rules binary subprocess returned exit
status 2"

However, without a detailed explanation of what the OP already has
done, it's only possible to help by guessing. Let alone that the OP
does insist in continuing doing several things beyond the OP's
understanding at once. The OP doesn't know how tmpfs works [1] and how
to build kernel packages. So why not forget the tmpfs learning curve for
the moment and just struggle with the kernel package learning curve? Why
doing two unfamiliar things at once? Why not starting with one
unfamiliar thing first?

Ralf
