The idle entry/exit code saves/restores GPRs in the stack "red zone"
(Protected Zone according to PowerPC64 ELF ABI v2). However, the offset
used for the first GPR is incorrect and overwrites the back chain - the
Protected Zone actually starts below the current SP. In practice this is
probably not
Although they are harmless, I think we should keep the consistency of
kernel coding style.
Thanks

I realise they're superfluous, but they're also harmless as far as I'm
aware.
