hexagon: Remove unusable symbols from the ptrace.h uapi (2023-10-25 15:54:24 +0200)
----------------------------------------------------------------
asm-generic updates for v6.7
The ia64 architecture gets its well-earned retirement as planned,
now that there is one last (mostly) working release that will
be maintained as an LTS kernel.
The architecture specific system call tables are updated for
the added map_shadow_stack() syscall and to remove references
to the long-gone sys_lookup_dcookie() syscall.
----------------------------------------------------------------
Note that the ia64 removal has a number of conflicts against
modified files from other pull requests. It might help to pull
this a few days later, after most of the other ones are already
there.

Dear all,
so the ia64 removal happened despite the efforts - not only from us - to
keep it alive in Linux. That is a - sad - fact now.
There was no real breakage for ia64 in the kernel that I know of since
[db3e33d] was merged five months ago and _if it ain't broke, don't fix it_.
Well, it's really broken now.
We built upon what others had accomplished before in the kernel and
outside of the kernel. We started to take care of existing problems
(glibc, gcc) and others also did their part in getting things fixed for
ia64 (grub). We gathered people around us that have both the required
machines and the interest to help out. And despite what others claim, we
are users of this architecture and continue to be and we are not alone.
We simply tried to take care of the architecture in and outside of
kernel space with the assumption that this was what was needed to keep
an architecture alive. But apparently that was either not good enough,
not wanted or simply not enough to prevent its removal.
At the moment I am out of ideas what other options there are, actually
I'm really puzzled here. Because what we tried to accomplish, isn't that
what you want for Linux: to arouse people's interest in working on the
kernel and ecosytem? Well, you were successful with that for ia64, but
removed it anyhow.
So I ask the simple question:
What needs to be done to get ia64 back into Linux?
All the best,
Frank

Well, I'd have personally been willing to resurrect it, but I was told
several times that other projects were basically just waiting for the
kernel support to die.
Has the itanium situation really changed?
The thing is, nobody doing new kernel code wants to deal with itanium,
so relegating it to the same situation that i386 support was ("it
still works in old kernels") doesn't seem to be a huge issue for the
people who actually want to use those machines.
That said, I'd be willing to resurrect itanium support, even though I
personally despise the architecture with a passion for being
fundamentally based on faulty design premises, and an implementation
based on politics rather than good technical design.
But only if it turns out to actually have some long-term active
interest (ie I'd compare it to the situation with m68k etc - clearly
dead architectures that we still support despite them being not
relevant - because some people care and they don't cause pain).
So I'd be willing to come back to the "can we resurrect it"
discussion, but not immediately - more along the lines of a "look,
we've been maintaining it out of tree for a year, the other
infrastructure is still alive, there is no impact on the rest of the
kernel, can we please try again"?

This made my day. :-)

Fully agreed.

I think this is a very reasonable approach. If the keeping the architecture
alive is sustainable, it should be possible to do that out of tree for a
given period of time.
Thanks,
Adrian

That's understandable, thank you for clarifying that. I was wondering
why Itanium and not Alpha, PA-RISC etc., this seems to give a clue to
that.

I agree with Adrian, that sounds very reasonable to me. If we want
Itanium to stay in kernel and it is a burden to other developers, it
is fair that we take the burden on us for the time being even if it
means overhead from maintaning an out-of-tree patch. For reference, I
already created a fork:
https://github.com/lenticularis39/linux-ia64/tree/master-revert-ia64-removal
and will try to maintain it building and working.
Also, I will see whether it is feasible to maintain it out-of-tree in
the following months, and if I manage to do so, I will have a much
better argument on why I should maintain it in-tree than my previous
"Hi, I heard you are deleting Itanium. I have only one unrelated
two-line commit in the kernel but I have a machine and will try to
maintain it, please don't remove it" post
(https://lore.kernel.org/linux-ia64/CAHtyXDfvS4OYLjOqALy74vR4w9DOFjJ9z8UOFeDpyjv7_PHNXw@mail.gmail.com/).
As I'm also a maintainer of the T2 SDE distribution, I will keep
building and testing it as part of it (there is even an enthusiast in
our community who runs Itanium Linux daily for some tasks).
I will revisit the topic here in case the effort succeeds for a longer
amount of time.

Well, we definitely made some progress in this regard. But as you wrote,
this was not a pressing issue as long as ia64 stayed in the kernel.
Which is why I wanted to concentrate on kernel support first and
foremost. My thinking was that a working architecture wouldn't be
dropped*. And with kernel support saved, we could have gone full steam
ahead into the other projects.
Well, we did proceed with tackling the problems in the other projects
anyhow from the start, but now the situation is a little different.

That is really something.
We'll see where this goes. I always hope for the best. (-:
If you feel like checking on our status, you know where to look (see my
email to you from 2023-09-23).
