Hi all,

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

  arch/riscv/include/asm/io.h

between commit:

  85731f537aaf ("mm/ioremap: pass pgprot_t to ioremap_prot() instead of unsigned long")

from th mm-unstable breanch of the mm tree and commit:

  a9ebcb88136c ("mm/memremap: Pass down MEMREMAP_* flags to arch_memremap_wb()")

from the tip 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.

This is now a conflict between the mm-stable tree and Linus' tree.

The fix for the merge-conflict looks good.
