The following configurations are failing for System/390:
* gcc-8-allmodconfig
* gcc-8-allnoconfig
* gcc-8-defconfig (+CONFIG_DEBUG_INFO_BTF=n)
* gcc-8-tinyconfig
* gcc-13-allmodconfig
* gcc-13-allnoconfig
* gcc-13-defconfig
* gcc-13-tinyconfig
* clang-17-allmodconfig

* clang-17-defconfig
* clang-17-tinyconfig
* clang-nightly-allmodconfig
* clang-nightly-allnoconfig
* clang-nightly-defconfig
* clang-nightly-tinyconfig
The error looks like this:

Bisection points to:
commit 1a5dd59623dc206de30df2d13316a3ce9be6821a
Author: Heiko Carstens <hca@...ux.ibm.com>
Date: Tue Oct 24 10:15:20 2023 +0200
s390/cmma: fix handling of swapper_pg_dir and invalid_pg_dir
commit 84bb41d5df48868055d159d9247b80927f1f70f9 upstream.
Reverting that commit made the build pass.
Reproducer:
tuxmake --runtime podman --target-arch s390 --toolchain gcc-13 --kconfig tinyconfig
Then, there's a PowerPC failure too on the following configurations:
* gcc-8-allmodconfig
* gcc-8-defconfig
* gcc-13-allmodconfig
* gcc-13-defconfig
* clang-17-defconfig
* clang-nightly-defconfig
That looks like this:

I guess it might be due to this:
commit fd018dfa8f0b963d65700d518596f9d834844fca
Author: Gaurav Batra <gbatra@...ux.vnet.ibm.com>

powerpc/pseries/iommu: enable_ddw incorrectly returns direct mapping for SR-IOV device
commit 3bf983e4e93ce8e6d69e9d63f52a66ec0856672e upstream.
Reverting that commit does make the build pass again.
Reproducer:
tuxmake --runtime podman --target-arch powerpc --toolchain gcc-13 --kconfig defconfig
