Several architectures override module_alloc() only to define address range for code allocations different than VMALLOC address space. Provide a generic implementation in execmem that uses the parameters for address space ranges, required alignment and page protections provided by architectures. The architectures must fill execmem_info structure and implement execmem_arch_setup() that returns a pointer to that structure. This way the execmem initialization won't be called from every architecture, but rather from a central place, namely a core_initcall() in execmem. The execmem provides execmem_alloc() API that wraps __vmalloc_node_range() with the parameters defined by the architectures. If an architecture does not implement execmem_arch_setup(), execmem_alloc() will fall back to module_alloc().
