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

From: Mark Brown <[email-masked]>

Hi all,

Today's linux-next merge of the drm tree got conflicts in:

  rust/kernel/lib.rs
  scripts/Makefile.build

between commit:

  7fa2b092b1ff8 ("rust: kbuild: remove `feature(...)`s that are now stable")

from the rust tree and commits:

  80df573af9ef3 ("rust: drm: gem: shmem: Add DRM shmem helper abstraction")
  3cc319d5f433a ("rust: enable the `generic_arg_infer` feature")
  f9f0b4a1f35d3 ("rust: interop: Add list module for C linked list interface")

from the drm 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.
