Subject: linux-next: manual merge of the rust tree with the arm64 tree

Hi all,

Today's linux-next merge of the rust tree got a conflict in:

rust/Makefile

between commit:

f82811e22b48 ("rust: Refactor the build target to allow the use of builtin targets")

from the arm64 tree and commit:

ecab4115c44c ("kbuild: mark `rustc` (and others) invocations as recursive")

from the rust tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging. You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.

The resolution looks good -- thanks!

This is now a conflict between the arm64 tree and Linus' tree.
