My question is, how to merge this series. I am touching all architectures, but the first patch is a prerequisite of the rest of this series. One possibility is to ask the x86 maintainers to pickup the first 5 patches for v5.12-rc1, and then send the rest for v5.13-rc1, splitting per-arch. I want the x86 maintainers to check the first 5 patches because I cleaned up the x32 code. I know x32 was considered for deprecation, but my motivation is to clean-up scripts across the tree without changing the functionality.
