After we support HAVE_ARCH_HUGE_VMAP, we can now enbale HAVE_ARCH_HUGE_VMALLOC
too. This feature has been used in kvmalloc and alloc_large_system_hash
for now. This feature can be disabled by kernel parameters "nohugevmalloc".

should be "select HAVE_ARCH_HUGE_VMALLOC if HAVE_ARCH_HUGE_VMAP"

this could also fix the lkp build issue.
