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

Hi all,

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

  arch/riscv/include/asm/pci.h

between commit:

  bb356ddb78b2 ("RISC-V: PCI: Avoid handing out address 0 to devices")

from the risc-v tree and commit:

  a2912b45b082 ("asm-generic: Add new pci.h and use it")

from the pci 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
