This looks like a bad conflict resolution of a patch in Andrew's set.
3394cb084a8d ("arm64: mte: add in-kernel MTE helpers") has reintroduced
set_sctlr_el1_tcf0() which was removed in e710c29e0177 ("arm64: mte:
make the per-task SCTLR_EL1 field usable elsewhere") (in arm64 tree).
But this doesn't happen in the original patch
arm64-mte-add-in-kernel-mte-helpers.patch in Andrew's set.

steps to reproduce:
# TuxMake is a command line tool and Python library that provides
# portable and repeatable Linux kernel builds across a variety of
# architectures, toolchains, kernel configurations, and make targets.
#
# TuxMake supports the concept of runtimes.
# See https://docs.tuxmake.org/runtimes/, for that to work it requires
# that you install podman or docker on your system.
#
# To install tuxmake on your system globally:
# sudo pip3 install -U tuxmake
#
# See https://docs.tuxmake.org/ for complete documentation.
