help
This symbol controls whether we build the 32-bit VDSO. We obviously
want to do that if we're building a 32-bit kernel. If we're building
- a 64-bit kernel then we only want a 32-bit VDSO if we're building for
- big endian. That is because the only little endian configuration we
- support is ppc64le which is 64-bit only.
