A couple hardened usercopy changes:
- drop now unneeded is_vmalloc_or_module() check; Laura Abbott
- use enum instead of literals for stack frame API; Sahara
mm/usercopy: Drop extra is_vmalloc_or_module() check
Previously virt_addr_valid() was insufficient to validate if virt_to_page()
could be called on an address on arm64. This has since been fixed up so
there is no need for the extra check. Drop it.
