Hi Mike,

This commit is making my intel box not boot in mm-unstable :>) I bisected it to
this commit.

For what it's worth, we've found the same under Xen too.

There's one concrete bug in the series, failing to cope with the absence
of superpages (fix in
https://lore.kernel.org/xen-devel/6bb03333-74ca-4c2c-85a8-72549b85a5b4@suse.com/ (local)
but not formally posted yet AFAICT).

Now sent out:

https://lore.kernel.org/lkml/20250103065631.26459-1-jgross@suse.com/T/#u (local)

Thanks,

Marek, Adam, can you try this patch? Although the reply here is for
another future series being worked on the fix is for commit
2e45474ab14f ("execmem: add support for cache of large ROX pages").

Hi Luis,

I suppose you're referring to the issue described here
https://lore.kernel.org/linux-mm/CAGcaFA2hdThQV6mjD_1_U+GNHThv84+MQvMWLgEuX+LVbAyDxg@mail.gmail.com/T/ (local)
Unfortnuetly this patch didn't help.

Best,
Marek
