linux-next: manual merge of the mm-nonmm-unstable tree with the mm,mm-fixes tree

Hi all,

Today's linux-next merge of the mm-nonmm-unstable tree got a conflict in:

mm/secretmem.c

between commits:

0d171c47f2be6 ("mm/secretmem: properly account locked pages")
a31a4988ca3e8 ("set_memory: add number of pages parameter to set_direct_map APIs")

from the mm,mm-fixes tree and commit:

d2c5e077cbeaf ("mm/secretmem: properly account locked pages")

from the mm-nonmm-unstable 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.
