Subject: [PATCH v11 01/14] uaccess: add untagged_addr definition for other arches
Date: Fri, 15 Mar 2019 20:51:25 +0100 [thread overview]
Message-ID: <bee403f76b40f37c6790d144a4142f293e0a7d9f.1552679409.git.andreyknvl__43954.278102477$1552679533$gmane$org@google.com> (raw)
In-Reply-To: <cover.1552679409.git.andreyknvl@google.com>
To allow arm64 syscalls to accept tagged pointers from userspace, we must
untag them when they are passed to the kernel. Since untagging is done in
generic parts of the kernel, the untagged_addr macro needs to be defined
for all architectures.
Define it as a noop for architectures other than arm64.
