Agree. At least i see a few users of it:

urezki@pc638:~/data/coding/linux-next.git$ grep -rn early_param ./arch/ | grep
vmalloc
./arch/arm/mm/mmu.c:1152:early_param("vmalloc", early_vmalloc);
./arch/unicore32/mm/mmu.c:276:early_param("vmalloc", early_vmalloc);
./arch/x86/mm/pgtable_32.c:86:early_param("vmalloc", parse_vmalloc);
