[PATCH AUTOSEL 6.6 01/47] hwtracing: hisi_ptt: Handle the interrupt in hardirq context

Otherwise we may violate the synchronization requirements of the perf core, referenced to the change of arm-ccn PMU commit 0811ef7e2f54 ("bus: arm-ccn: fix PMU interrupt flags").

[PATCH 1/4] drm/i915/dmc: Don't enable any pipe DMC events

by Ville Syrjala

From: Ville Syrjälä <ville.syrjala(a)linux.intel.com> The pipe DMC seems to be making a mess of things in ADL. Various weird symptoms have been observed such as missing vblank irqs, typicalle happening when using multiple displays. Keep all pipe DMC event handlers disabled until needed (which is never atm). This is also what Windows does on ADL+. We can also drop DG2 from disable_all_flip_queue_events() since on DG2 the pipe DMC is the one that handles the flip queue events.

Turns out this one requires another commit to go with it, both for v6.7-rc* and stable backports. I was just a bit too late with it for v6.7-rc4 [1]. Please hold off with all stable backports of this until you can backport 96d7e7940136 ("drm/i915: Check pipe active state in {planes,vrr}_{enabling,disabling}()") from drm-intel-fixes with it. It should find its way to v6.7-rc5. Thanks, and sorry for the mess. :( BR, Jani.

[PATCH] drm/i915: fix display ver 12-13 fault error handling

by Jani Nikula

Unless I'm completely misreading the bspec, there are no defined bits for plane gtt fault errors in DE PIPE IIR for a display versions 12-14. This would explain why DG2 in the linked bug is getting thousands of fault errors.

[PATCH 5.15.y] mm: fix oops when filemap_map_pmd) without prealloc_pte

by Hugh Dickins

syzbot reports oops in lockdep's __lock_acquire(), called from __pte_offset_map_lock() called from filemap_map_pages(); or when I run the repro, the oops comes in pmd_install(), called from filemap_map_pmd() called from filemap_map_pages(), just before the __pte_offset_map_lock(). The problem is that filemap_map_pmd() has been assuming that when it finds pmd_none(), a page table has already been prepared in prealloc_pte; and indeed do_fault_around() has been careful to preallocate one there, when it finds pmd_none(): but what if *pmd became none in between? My 6.6 mods in mm/khugepaged.c, avoiding mmap_lock for write, have made it easy for *pmd to be cleared while servicing a page fault; but even before those, a huge *pmd might be zapped while a fault is serviced. The difference in symptomatic stack traces comes from the "memory model" in use: pmd_install() uses pmd_populate() uses page_to_pfn(): in some models that is strict, and will oops on the NULL prealloc_pte; in other models, it will construct a bogus value to be populated into *pmd, then __pte_offset_map_lock() oops when trying to access split ptlock pointer (or some other symptom in normal case of ptlock embedded not pointer).
