This adds a patch to support CONFIG_UIDGID_STRICT_TYPE_CHECKS being activated in
the kernel config (selected by CONFIG_USER_NS for example).
When this kernel option is enabled, current->cred->uid is a structure rather
than a simple integer type (uid_t and gid_t), so we need to check for that and
also pass the current user namespace where needed.
