[merged] mm-_install_special_mapping-apply-vm_locked_clear_mask.patch removed from -mm tree

[Andrew Morton]

The patch titled
     Subject: mm: _install_special_mapping() apply VM_LOCKED_CLEAR_MASK
has been removed from the -mm tree.  Its filename was
     mm-_install_special_mapping-apply-vm_locked_clear_mask.patch

This patch was dropped because it was merged into mainline or a subsystem tree

Subject: mm: _install_special_mapping() apply VM_LOCKED_CLEAR_MASK

_install_special_mapping() adds the VM_SPECIAL bit VM_DONTEXPAND (and
never attempts to update locked_vm), so it ought to be consistent with
mmap_region() and mlock_fixup(), making sure not to add VM_LOCKED or
VM_LOCKONFAULT.  I doubt that this fixes any problem in practice: just do
it for consistency.
