no-MMU: expose vmalloc_huge() for alloc_large_system_hash()
It turns out that for the CONFIG_MMU=n builds, vmalloc_huge() was never defined, since it's defined in mm/vmalloc.c, which doesn't get built for the no-MMU configurations. Just implement the trivial wrapper for the no-MMU case too. In fact, just make it an alias to the existing __vmalloc() function that has the same signature.
