It seems I accidentally switched the guard on linux/elf-fdpic.h from #ifdef __KERNEL__ to #ifndef __KERNEL__ when attempting to expand the guarded region to cover the elf_fdpic_params struct when doing the UAPI split - with the result that the struct became unavailable to kernel code. Move incorrectly guarded bits back to the kernelspace header. Whilst we're at it, the __KERNEL__ guards can be deleted as they're no longer necessary.
