nommu: Provide is_vmalloc_addr() stub.
Introduced in commit-id 9e2779fa281cfda13ac060753d674bbcaa23367e and
ifdef'ed out for nommu in 8ca3ed87db062201e1fa15b64a9214e193fc3a8a, both
approaches end up breaking the nommu build in different ways. An
impressive feat for a 2-liner.
Current is_vmalloc_addr() users fall in to two camps:
- Determining whether to use vfree()/kfree()
- Whether to do vmlist traversal (only /proc/kcore).
Since we don't support /proc/kcore on nommu, that leaves the
vfree()/kfree() determination use cases. nommu vfree() happens to be a
wrapper to kfree() anyways, so is_vmalloc_addr() can always return 0
and end up with the right behaviour.
