These definitions were needed to build arch/arm64/kernel/ptrace.c with CONFIG_COMPAT64 a long time ago, before "arm64: ptrace: Support compat64". This is not the case any more, however since "fs/compat_binfmt_elf: Align compat64 with compat32" we do need to define compat_elf_gregset_t to keep linux/elfcore-compat.h happy.
This is the correct approach and there is no plan to change it, so let's remove the outdated TODO.

Given we've already handled compat_elf_gregset_t and the rest, i'd say +1
Indeed, thanks for having a look. Now in next.
