For the patch below, what are the "real world use cases" that would
cause this to be needed in the stable kernel trees?  Is there an
in-kernel module that is affected by this limitation?

There are no in-kernel modules which are affected, the "real world"
scenario is debug modules generated by Ksplice.

Also, when was "a while ago" exactly?

Uncertain, but according to my tests for this patch vmalloc is fine
with allocating large blocks on a 2.6.18 kernel.
