Public bug reported: SRU Justification
Impact: The upstream process for stable tree updates is quite similar in scope to the Ubuntu SRU process, e.g., each patch has to demonstrably fix a bug, and each patch is vetted by upstream by originating either directly from a mainline/stable Linux tree or a minimally backported form of that patch. The following upstream stable patches should be included in the Ubuntu kernel: v5.4.76 upstream stable release from git://git.kernel.org/ drm/i915: Break up error capture compression loops with cond_resched() drm/i915/gt: Delay execlist processing for tgl drm/i915: Drop runtime-pm assert from vgpu io accessors ASoC: Intel: Skylake: Add alternative topology binary name UBUNTU: update dkms package versions linkage: Introduce new macros for assembler symbols arm64: asm: Add new-style position independent function annotations arm64: lib: Use modern annotations for assembly functions arm64: Change .weak to SYM_FUNC_START_WEAK_PI for arch/arm64/lib/mem*.S tipc: fix use-after-free in tipc_bcast_get_mode ptrace: fix task_join_group_stop() for the case when current is traced cadence: force nonlinear buffers to be cloned chelsio/chtls: fix memory leaks caused by a race chelsio/chtls: fix always leaking ctrl_skb gianfar: Replace skb_realloc_headroom with skb_cow_head for PTP gianfar: Account for Tx PTP timestamp in the skb headroom ionic: check port ptr before use ip_tunnel: fix over-mtu packet send fail without TUNNEL_DONT_FRAGMENT flags net: usb: qmi_wwan: add Telit LE910Cx 0x1230 composition powerpc/vnic: Extend "failover pending" window sctp: Fix COMM_LOST/CANT_STR_ASSOC err reporting on big-endian platforms sfp: Fix error handing in sfp_probe() Fonts: Replace discarded const qualifier ALSA: hda/realtek - Fixed HP headset Mic can't be detected ALSA: hda/realtek - Enable headphone for ASUS TM420 ALSA: usb-audio: Add implicit feedback quirk for Zoom UAC-2 ALSA: usb-audio: add usb vendor id as DSD-capable for Khadas devices ALSA: usb-audio: Add implicit feedback quirk for Qu-16 ALSA: usb-audio: Add implicit feedback quirk for MODX mm: mempolicy: fix potential pte_unmap_unlock pte error lib/crc32test: remove extra local_irq_disable/enable kthread_worker: prevent queuing delayed work from timer_fn when it is being canceled mm: always have io_remap_pfn_range() set pgprot_decrypted() gfs2: Wake up when sd_glock_disposal becomes zero ring-buffer: Fix recursion protection transitions between interrupt context mtd: spi-nor: Don't copy self-pointing struct around ftrace: Fix recursion check for NMI test ftrace: Handle tracing when switching between context regulator: defer probe when trying to get voltage from unresolved supply spi: bcm2835: fix gpio cs level inversion tracing: Fix out of bounds write in get_trace_buf futex: Handle transient "ownerless" rtmutex state correctly ARM: dts: sun4i-a10: fix cpu_alert temperature arm64: dts: meson: add missing g12 rng clock x86/kexec: Use up-to-dated screen_info copy to fill boot params of: Fix reserved-memory overlap detection drm/sun4i: frontend: Rework a bit the phase data drm/sun4i: frontend: Reuse the ch0 phase for RGB formats drm/sun4i: frontend: Fix the scaler phase on A33 blk-cgroup: Fix memleak on error path blk-cgroup: Pre-allocate tree node on blkg_conf_prep scsi: core: Don't start concurrent async scan on same host drm/amdgpu: add DID for navi10 blockchain SKU scsi: ibmvscsi: Fix potential race after loss of transport vsock: use ns_capable_noaudit() on socket create nvme-rdma: handle unexpected nvme completion data length nvmet: fix a NULL pointer dereference when tracing the flush command drm/vc4: drv: Add error handding for bind ACPI: NFIT: Fix comparison to '-ENXIO' usb: cdns3: gadget: suspicious implicit sign extension drm/nouveau/nouveau: fix the start/end range for migration drm/nouveau/gem: fix "refcount_t: underflow;
