delay the removal of this symbol export by one more kernel release,
giving external modules such as VirtualBox a chance to stop using it.

		---------------------------

		What: init_mm export
		When: 2.6.26
		Why: Not used in-tree. The current out-of-tree users used it to
		work around problems in the CPA code which should be resolved
		by now. One usecase was described to provide verification code
		of the CPA operation. That's a good idea in general, but such
		code / infrastructure should be in the kernel and not in some
		out-of-tree driver.
