Caused by commit 64d26fb2ad1f2 (xen: privcmd: fix ioeventfd crash under PV domain) I have used the tree from next-20260803 instead.Sorry for the trouble! Did not expect that to get applied so quickly.. I had noticed recently in my own testing that that patch wasn't actually ready to go in due to the symbol visibility issue, right. I'll work on resolving it. ~val
I'm pretty sure mm maintainers wouldn't like init_mm to be exported to modules. I'd go for a special variant of xen_remap_domain_mfn_array() mapping just a single pfn into init_mm. This could be implemented in mmu_pv.c avoiding the need to export init_mm. Juergen
