The patch looks good, but I'd suggest adding a oneline description
referencing that ia64 as a whole is removed.

I see that you created a couple of patches looking for __ia64__
but not CONFIG_IA64. If we get consensus on patch 1, we should
do that as well, let me know if you you want to add those or
would like me to help here.

I can probably do the same recursive check for removed Kconfig
options that I used for finding dead code after the boardfile
removal.
