linux-next: manual merge of the tip tree

[Mark Brown]

Today's linux-next merge of the kvm-arm tree got conflicts in
mm/mprotect.c between c3d16e1652 (mm: migration: do not lose soft dirty
bit if page is in migration state) from Linus' tree and e920e14c (mm: Do
not flush TLB during protection change if !pte_present &&
!migration_entry) from the tip tree.

I've fixed up as below and can carry as required.

diff --cc mm/mprotect.c

  		}
  	} while (pte++, addr += PAGE_SIZE, addr != end);
  	arch_leave_lazy_mmu_mode();
