linux-next: manual merge of the akpm-current tree with the kvm tree

Hi Andrew,

Today's linux-next merge of the akpm-current tree got a conflict in
arch/x86/kvm/mmu.c between commit 9bb4f6b15ec0 ("KVM: MMU: drop unneeded
checks") from the kvm tree and commit "hlist: drop the node parameter
from iterators" from the akpm-current tree.

I fixed it up (the conflicts were caused by bad white space changes in
the akpm tree patch) and can carry the fix as necessary (no action is
required).

hm, not sure what you meant by "bad" but that patch went and took the
nice fits-in-80-cols kvm code and mucked it all up.  Shall unmuck
tomorrow.

"bad" in the sense that there was lots of white space changes to lines
not otherwise touched by the patch and those white space changes
introduced extra levels of tabs (so the indentation was incorrect) and
merged some lines.  I unmucked some of it, but got bored :-)

linux-next: manual merge of the akpm-current tree with the kvm tree

[Stephen Rothwell]

Hi Andrew,

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

  arch/x86/kvm/mmu.c

between commits:

  7ee0e5b29d27 ("KVM: x86: MMU: Remove unused parameter of __direct_map()")
  029499b47738 ("KVM: x86: MMU: Make mmu_set_spte() return emulate value")

from the kvm tree and commit:

  7fd3f3e7c320 ("kvm: rename pfn_t to kvm_pfn_t")

from the akpm-current tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).
