Just to add a data point: renaming an ARM-named-but-not-ARM-specific file when
another architecture adopts it does have precedent. See the EFI stub/init, which
were renamed precisely to drop the misleading "arm" name once RISC-V reused
them:

2e0eb483c058 ("efi/libstub: Move arm-stub to a common file")
f30f242fb131 ("efi: Rename arm-init to efi-init common for all arch")

The justification there was the same as here — the code isn't actually
ARM-specific, so the ARM name is misleading once a second arch uses it.

That said, I agree it shouldn't be done purely for cosmetics; it makes sense
when it's paired with the real change (dropping the ARM dependency).

Thanks,
