linux-next: manual merge of the generic-ioremap tree with the risc-v tree

[Stephen Rothwell]

Hi all,

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

  arch/riscv/include/asm/io.h

between commit:

  0c3ac28931d5 ("riscv: separate MMIO functions into their own header file")

from the risc-v tree and commits:

  d092a8707326 ("arch: rely on asm-generic/io.h for default ioremap_* definitions")
  38af57825313 ("riscv: use the generic ioremap code")

from the generic-ioremap 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.
