Hi Oscar,
Hi Naresh,
While building the linux next 20210310 tag for x86_64 architecture with clang-12 and gcc-9 the following warnings / errors were noticed.

Yes, this was also reported by Zi Yan here [1]. Looking into your .config, seems to be the same issue as you have CONFIG_SPARSE_VMEMMAP but !CONFIG_MEMORY_HOTPLUG.
This version fixes those compilation errors.
Thanks for reporting it anyway!

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.
tuxmake --runtime podman --target-arch x86_64 --toolchain clang-12 --kconfig defconfig --kconfig-add https://builds.tuxbuild.com/1pYCPt4WlgSfSdv1BULm6ABINeJ/config
