This allows much code to deal with vector_page mappings to be eliminated. On a BEAGLEBONE kernel, this saves 8KB of text and instructions that never have to be executed. (The PJ4B has VBAR but doesn't implement the security extensions it is part of so a method was needed to allow it use VBAR with relying on the default test for the security extensions.)
