[Linaro-mm-sig] decruft the vmalloc API

Hi all,

Peter noticed that with some dumb luck you can toast the kernel address space with exported vmalloc symbols.

I used this as an opportunity to decruft the vmalloc.c API and make it much more systematic. This also removes any chance to create vmalloc mappings outside the designated areas or using executable permissions from modules. Besides that it removes more than 300 lines of code.
