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

Hi all,

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

  arch/riscv/include/asm/set_memory.h

between commit:

  8d91b0973358 ("riscv: Consistify protect_kernel_linear_mapping_text_rodata() use")

from the risc-v tree and commit:

  e022d55b4d97 ("set_memory: allow set_direct_map_*_noflush() for multiple pages")

from the akpm 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.

Cheers,
Stephen Rothwell
