Subject: linux-next: manual merge of the risc-v tree with Linus' tree

Hi all,

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

  arch/riscv/Makefile

between commit:

  ef10bdf9c3e6 ("riscv: Kconfig.socs: Split ARCH_CANAAN and SOC_CANAAN_K210")

from Linus' tree and commits:

  3b938e231b66 ("riscv: merge two if-blocks for KBUILD_IMAGE")
  c1f59d035966 ("riscv: make image compression configurable")

from the risc-v 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.

Stephen Rothwell
