linux-next: manual merge of the rust tree with the origin tree

Hi all,

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

  tools/include/linux/lockdep.h

between commit:

  3a49cc22d31ec ("tools/lib/lockdep: drop leftover liblockdep headers")

from the origin tree and commit:

  ab4cc3d9c564d ("kallsyms: increase maximum kernel symbol length to 512")

from the rust tree.

I fixed it up by removing lockdep.h again 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.
