Yonghong Song says:

====================
Previous maximum supported integer bit width is 64. But
the __int128 type has been supported by most (if not all)
64bit architectures including bpf for both gcc and clang.

The kernel itself uses __int128 for x64 and arm64. Some bcc
tools are using __int128 in bpf programs to describe ipv6
addresses. Without 128bit int support, the vmlinux BTF won't
work and those bpf programs using __int128 cannot utilize BTF.

This patch set therefore implements BTF __int128 support.
