+
+commit 43e2b37e2ab660c3565d4cff27922bc70e79c3f1 upstream.
+
+In some scenarios, the DPT object gets shrunk but
+the actual framebuffer did not and thus its still
+there on the DPT's vm->bound_list. Then it tries to
+rewrite the PTEs via a stale CPU mapping. This causes panic.

+Subject: drm/i915: Fix audio component initialization
+
+From: Imre Deak <imre.deak@intel.com>
+
+commit 75800e2e4203ea83bbc9d4f63ad97ea582244a08 upstream.
+
+After registering the audio component in i915_audio_component_init()
+the audio driver may call i915_audio_component_get_power() via the
+component ops. This could program AUD_FREQ_CNTRL with an uninitialized
+value if the latter function is called before display.audio.freq_cntrl
+gets initialized. The get_power() function also does a modeset which in
+the above case happens too early before the initialization step and
+triggers the
+
+"Reject display access from task"
+
+error message added by the Fixes: commit below.
+
+Fix the above issue by registering the audio component only after the
+initialization step.
+
+Fixes: 87c1694533c9 ("drm/i915: save AUD_FREQ_CNTRL state at audio domain suspend")

+Subject: drm/i915/gt: Disarm breadcrumbs if engines are already idle
+
+From: Chris Wilson <chris@chris-wilson.co.uk>
+
+commit 70cb9188ffc75e643debf292fcddff36c9dbd4ae upstream.
+
+The breadcrumbs use a GT wakeref for guarding the interrupt, but are
+disarmed during release of the engine wakeref. This leaves a hole where
+we may attach a breadcrumb just as the engine is parking (after it has
+parked its breadcrumbs), execute the irq worker with some signalers still
+attached, but never be woken again.
+
+That issue manifests itself in CI with IGT runner timeouts while tests
+are waiting indefinitely for release of all GT wakerefs.

+
+commit 39bc27bd688066a63e56f7f64ad34fae03fbe3b8 upstream.
+
+Lack of check for copy-on-write (COW) mapping in drm_gem_shmem_mmap
+allows users to call mmap with PROT_WRITE and MAP_PRIVATE flag
+causing a kernel panic due to BUG_ON in vmf_insert_pfn_prot:
+BUG_ON((vma->vm_flags & VM_PFNMAP) && is_cow_mapping(vma->vm_flags));
+
+Return -EINVAL early if COW mapping is detected.
+
+This bug affects all drm drivers using default shmem helpers.
+It can be reproduced by this simple example:
+void *ptr = mmap(0, size, PROT_WRITE, MAP_PRIVATE, fd, mmap_offset);
+ptr[0] = 0;

+Subject: pmdomain: ti-sci: Fix duplicate PD referrals
+
+From: Tomi Valkeinen <tomi.valkeinen@ideasonboard.com>
+
+commit 670c900f69645db394efb38934b3344d8804171a upstream.
+
+When the dts file has multiple referrers to a single PD (e.g.
+simple-framebuffer and dss nodes both point to the DSS power-domain) the
+ti-sci driver will create two power domains, both with the same ID, and
+that will cause problems as one of the power domains will hide the other
+one.
+
+Fix this checking if a PD with the ID has already been created, and only
+create a PD for new IDs.

+Subject: riscv: rewrite __kernel_map_pages() to fix sleeping in invalid context
+
+From: Nam Cao <namcao@linutronix.de>
+
+commit fb1cf0878328fe75d47f0aed0a65b30126fcefc4 upstream.
+
+__kernel_map_pages() is a debug function which clears the valid bit in page
+table entry for deallocated pages to detect illegal memory accesses to
+freed pages.
+
+This function set/clear the valid bit using __set_memory(). __set_memory()
+acquires init_mm's semaphore, and this operation may sleep. This is
+problematic, because __kernel_map_pages() can be called in atomic context,
+and thus is illegal to sleep. An example warning that this causes:
+
+BUG: sleeping function called from invalid context at kernel/locking/rwsem.c:1578
+in_atomic(): 1, irqs_disabled(): 0, non_block: 0, pid: 2, name: kthreadd
+preempt_count: 2, expected: 0
+CPU: 0 PID: 2 Comm: kthreadd Not tainted 6.9.0-g1d4c6d784ef6 #37

+
+Rewrite this function with apply_to_existing_page_range(). It is fine to
+not have any locking, because __kernel_map_pages() works with pages being
+allocated/deallocated and those pages are not changed by anyone else in the
+meantime.

+Subject: rtla/auto-analysis: Replace \t with spaces
+
+From: Daniel Bristot de Oliveira <bristot@kernel.org>
+
+commit a40e5e4dd0207485dee75e2b8e860d5853bcc5f7 upstream.
+
+When copying timerlat auto-analysis from a terminal to some web pages or
+chats, the \t are being replaced with a single ' ' or ' ', breaking
+the output.
+
+For example:
+ ## CPU 3 hit stop tracing, analyzing it ##
+ IRQ handler delay: 1.30 us (0.11 %)
+ IRQ latency: 1.90 us
+ Timerlat IRQ duration: 3.00 us (0.24 %)
+ Blocking thread: 1223.16 us (99.00 %)
+ insync:4048 1223.16 us
+ IRQ interference 4.93 us (0.40 %)
+ local_timer:236 4.93 us
+ ------------------------------------------------------------------------
+ Thread latency: 1235.47 us (100%)
+
+Replace \t with spaces to avoid this problem.

+Subject: rtla/timerlat: Simplify "no value" printing on top
+
+From: Daniel Bristot de Oliveira <bristot@kernel.org>
+
+commit 5f0769331a965675cdfec97c09f3f6e875d7c246 upstream.
+
+Instead of printing three times the same output, print it only once,
+reducing lines and being sure that all no values have the same length.
+
+It also fixes an extra '\n' when running the with kernel threads, like
+here:
+
+ =============== %< ==============
+ Timer Latency
+
+ 0 00:00:01 | IRQ Timer Latency (us) | Thread Timer Latency (us)
+ CPU COUNT | cur min avg max | cur min avg max
+ 2 #0 | - - - - | 161 161 161 161
+ 3 #0 | - - - - | 161 161 161 161
+ 8 #1 | 54 54 54 54 | - - - -'\n'
+
+ ---------------|----------------------------------------|---------------------------------------
+ ALL #1 e0 | 54 54 54 | 161 161 161
+ =============== %< ==============
+
+This '\n' should have been removed with the user-space support that
+added another '\n' if not running with kernel threads.
