Hi Ard.

John is not the "only remaining user". I also reported the problem. I am sorry I don't update the kernel every month. Yes there might have been more than 30 days between updates.


Thanks for the report.

Apologies if that sounded a bit callous but it does help get some
clarity regarding the ia64 situation. Essentially, we have a very
small number of downstream users but no dedicated developers or
maintainers. That is still not a great situation.

I'd prefer if we don't remove the Itanium McKinley+ support but I'll understand if it must.


If you are invested in keeping Itanium alive, how much effort would
you be willing to spend yourself on testing and reviewing Itanium
changes?

It isn't just that. Trying to build ia64:allmodconfig with gcc 11.2
fails due to build warning(s) which are now errors, and the same
build with gcc 11.3 or later (and binutils 2.32 or later) fails
completely with
    Error: Register number out of range 0..1
and similar all over the place. So there isn't just code bitrot,
there is also compiler and/or binutils bitrot.
