Subject: linux-next: manual merge of the kbuild tree with Lnus' tree

Hi all,

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

  arch/riscv/Kconfig

between commit:

  41f9049cff32 ("riscv: Only allow LTO with CMODEL_MEDANY")

from Lnus' tree and commit:

  6578a1ff6aa4 ("riscv: Remove version check for LTO_CLANG selects")

from the kbuild tree.

I fixed it up (I think - 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.

Cheers,
Stephen Rothwell
