SubjectRe: [PATCH v15 00/17] arm64: untag user pointers passed to the kernel
Thanks for a lot of valuable input! I've read through all the replies
and got somewhat lost. What are the changes I need to do to this
series?

1. Should I move untagging for memory syscalls back to the generic
code so other arches would make use of it as well, or should I keep
the arm64 specific memory syscalls wrappers and address the comments
on that patch?

2. Should I make untagging opt-in and controlled by a command line argument?

3. Should I "add Documentation/core-api/user-addresses.rst to describe
proper care and handling of user space pointers with untagged_addr(),
with examples based on all the cases seen so far in this series"?
Which examples specifically should it cover?

Is there something else?
