Andrey Konovalov 9d63092417 UPSTREAM: uaccess: add noop untagged_addr definition
(Upstream commit d93445225cd3c8eb0bf1350c04875576428b45b4).

Architectures that support memory tagging have a need to perform untagging
(stripping the tag) in various parts of the kernel. This patch adds an
untagged_addr() macro, which is defined as noop for architectures that do
not support memory tagging. The oncoming patch series will define it at
least for sparc64 and arm64.
