linux-next: manual merge of the loongarch tree with the origin tree

[Mark Brown]

Hi all,

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

  arch/loongarch/mm/init.c

between commit:

  6215d9f4470fb ("arch, mm: consolidate empty_zero_page")

from the origin tree and commit:

  8b81576c16c06 ("LoongArch: Add HIGHMEM (PKMAP and FIX_KMAP) support")

from the loongarch 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.
