+This makes the Linux kernel build as ELFv2 on big endian ppc64. The upstream
+doesn't seem to be interested in this but it's a small patch that is unlikely
+to break/easy to remake and in worst case can always be ditched.
+
+Using ELFv2 has some potential performance benefits and is already always used
+on little endian. It requires a relatively modern toolchain, which we already
+have.
+
+Ping q66 if it does not apply.

+support for box86 and thus reasonably fast emulation of 32-bit x86 games).

+
+This allows compat_sys calls with 64-bit args to function correctly
+when called by ppcle userlands on ppc64le.
+
+Tested with `file /bin/bash` (pread64) and `truncate -s 5G test` (ftruncate64).
