x86: delay the export removal of init_mm
delay the removal of this symbol export by one more kernel release,
giving external modules such as VirtualBox a chance to stop using it.

 	is largely pointless as without a lot of work only the most
 	trivial of Solaris binaries can work with the emulation code.

+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.
