In the meantime, can you rebase the tree once more to split out the driver patches and make sure the architecture port without the drivers still builds cleanly (at least defconfig and allmodconfig) using the compiler from [1]? If this requires additional patches, please add them on top. Once that is done, we can ask Linus to consider merging the branch for the architecture port, while you keep working with the pci and irqchip maintainers to merge the drivers either for 5.19 or a future release. While this means merging a branch that does not actually work on any hardware by itself, it should be sufficient for the libc patches to consider the ABI stable, and it is consistent with how we keep CPU architecture support separate from platform driver support elsewhere.
