An alternative would be to provide a vmalloc_no_huge function in generic
code (similar to vmalloc_32) (or if preferred in s390 base architecture code)
Something like
void *vmalloc_no_huge(unsigned long size)
{
return __vmalloc_node_flags(size, NUMA_NO_NODE,VM_NO_HUGE_VMAP |
GFP_KERNEL | __GFP_ZERO);
}
EXPORT_SYMBOL(vmalloc_no_huge);
or a similar vzalloc variant.Exactly. Given that this seems to be a weird pecularity of legacy s390 interfaces I'd only export it for 390 for now, although for documentation purposes I'd probably still keep it in vmalloc.c.
