       "Fixes two issues with the Qualcomm SA8775P platform:
      
         - Some minor device tree binding flunky that is nice to iron out but
           more importantly:
      
         - Support the increased interrupt targets mask from 3 to 4 bits,
           making interrupts with higher (hardware) numbers work"

      Pull ARM SoC fixes from Arnd Bergmann:
       "As usual, mostly DT fixes for the major Arm platforms from Qualcomm
        and NXP, plus a bit for Rockchips and others:
      
        The qualcomm fixes mainly deal with their higher-end arm64 devices
        trees, fixing issues in L3 interconnect, crypto, thermal, UFS and a
        regression for the DSI phy.
      
        NXP i.MX has two correctness fixes for the 64-bit chips, dealing with
        the imx93 "anatop" module and the CSI interface. On the 32-bit side,
        there are functional fixes for RTC, display and SD card intefaces.
      
        Rockchip fixes are for wifi support on certain boards, a eMMC
        stability and DT build warnings.
      
        On TI OMAP, a regulator is described in DT to avoid problems with the
        ethernet phy initialization.
      
        The code changes include a missing MMIO serialization on OMAP, plus a
        few minor fixes on ASpeed and AMD/Zynq chips"

      drm/qxl: fix UAF on handle creation · c611589b
      Wander Lairson Costa authored
      qxl_mode_dumb_create() dereferences the qobj returned by
      qxl_gem_object_create_with_handle(), but the handle is the only one
      holding a reference to it.
      
      A potential attacker could guess the returned handle value and closes it
      between the return of qxl_gem_object_create_with_handle() and the qobj
      usage, triggering a use-after-free scenario.
      
      Reproducer:
      
      int dri_fd =-1;
      struct drm_mode_create_dumb arg = {0};
      
      void gem_close(int handle);
      
      void* trigger(void* ptr)
      {
      	int ret;
      	arg.width = arg.height = 0x20;
      	arg.bpp = 32;
      	ret = ioctl(dri_fd, DRM_IOCTL_MODE_CREATE_DUMB, &arg);
      	if(ret)
      	{
      		perror("[*] DRM_IOCTL_MODE_CREATE_DUMB Failed");
      		exit(-1);
      	}
      	gem_close(arg.handle);
      	while(1) {
      		struct drm_mode_create_dumb args = {0};
      		args.width = args.height = 0x20;
      		args.bpp = 32;
      		ret = ioctl(dri_fd, DRM_IOCTL_MODE_CREATE_DUMB, &args);
      		if (ret) {
      			perror("[*] DRM_IOCTL_MODE_CREATE_DUMB Failed");
      			exit(-1);
      		}
      
      		printf("[*] DRM_IOCTL_MODE_CREATE_DUMB created, %d\n", args.handle);
      		gem_close(args.handle);
      	}
      	return NULL;
      }
      
      void gem_close(int handle)
      {

      	args.handle = handle;
      	int ret = ioctl(dri_fd, DRM_IOCTL_GEM_CLOSE, &args); // gem close handle
      	if (!ret)
      		printf("gem close handle %d\n", args.handle);

      Disabling lock debugging due to kernel taint
      
      Instead of returning a weak reference to the qxl_bo object, return the
      created drm_gem_object and let the caller decrement the reference count
      when it no longer needs it. As a convenience, if the caller is not
      interested in the gobj object, it can pass NULL to the parameter and the
      reference counting is descremented internally.
      
      The bug and the reproducer were originally found by the Zero Day Initiative project (ZDI-CAN-20940).

      qede: fix firmware halt over suspend and resume · 2eb9625a
      Manish Chopra authored
      While performing certain power-off sequences, PCI drivers are
      called to suspend and resume their underlying devices through
      PCI PM (power management) interface. However this NIC hardware
      does not support PCI PM suspend/resume operations so system wide
      suspend/resume leads to bad MFW (management firmware) state which
      causes various follow-up errors in driver when communicating with
      the device/firmware afterwards.
      
      To fix this driver implements PCI PM suspend handler to indicate
      unsupported operation to the PCI subsystem explicitly, thus avoiding
      system to go into suspended/standby mode.
      
      Without this fix device/firmware does not recover unless system
      is power cycled.

      sock: Fix misuse of sk_under_memory_pressure() · 2d0c88e8
      Abel Wu authored
      The status of global socket memory pressure is updated when:
      
        a) __sk_mem_raise_allocated():
      
      	enter: sk_memory_allocated(sk) >  sysctl_mem[1]
      	leave: sk_memory_allocated(sk) <= sysctl_mem[0]
      
        b) __sk_mem_reduce_allocated():
      
      	leave: sk_under_memory_pressure(sk) &&
      		sk_memory_allocated(sk) < sysctl_mem[0]
      
      So the conditions of leaving global pressure are inconstant, which
      may lead to the situation that one pressured net-memcg prevents the
      global pressure from being cleared when there is indeed no global
      pressure, thus the global constrains are still in effect unexpectedly
      on the other sockets.
      
      This patch fixes this by ignoring the net-memcg's pressure when
      deciding whether should leave global memory pressure.
      
      Fixes: e1aab161 ("socket: initial cgroup code.")

      asm-generic: partially revert "Unify uapi bitsperlong.h for arm64, riscv and loongarch" · 6e8d9690
      Arnd Bergmann authored
      Unifying the asm-generic headers across 32-bit and 64-bit architectures
      based on the compiler provided macros was a good idea and appears to work
      with all user space, but it caused a regression when building old kernels
      on systems that have the new headers installed in /usr/include, as this
      combination trips an inconsistency in the kernel's own tools/include
      headers that are a mix of userspace and kernel-internal headers.
      
      This affects kernel builds on arm64, riscv64 and loongarch64 systems that
      might end up using the "#define __BITS_PER_LONG 32" default from the old
      tools headers. Backporting the commit into stable kernels would address
      this, but it would still break building kernels without that backport,
      and waste time for developers trying to understand the problem.
      
      arm64 build machines are rather common, and on riscv64 this can also
      happen in practice, but loongarch64 is probably new enough to not
      be used much for building old kernels, so only revert the bits
      for arm64 and riscv.

      Qualcomm ARM64 fixes for v6.5
      
      This corrects the invalid path specifier for L3 interconnects in the CPU
      nodes of SM8150 and SM8250. It corrects the compatible of the SC8180X L3
      node, to pass the binding check.
      
      The crypto core, and its DMA controller, is disabled on SM8350 to avoid
      the system from crashing at boot while the issue is diagnosed.
      
      A thermal zone node name conflict is resolved for PM8150L, on the RB5
      board.
      
      The UFS vccq voltage is corrected on the SA877P Ride platform, to
      address observed stability issues.
      
      The reg-names of the DSI phy on SC7180 are restored after an accidental
      search-and-replace update.

      Revert "drm/edid: Fix csync detailed mode parsing" · 50b6f2c8
      Jani Nikula authored
      This reverts commit ca62297b.
      
      Commit ca62297b ("drm/edid: Fix csync detailed mode parsing") fixed
      EDID detailed mode sync parsing. Unfortunately, there are quite a few
      displays out there that have bogus (zero) sync field that are broken by
      the change. Zero means analog composite sync, which is not right for
      digital displays, and the modes get rejected. Regardless, it used to
      work, and it needs to continue to work. Revert the change.
      
      Rejecting modes with analog composite sync was the part that fixed the
      gitlab issue 8146 [1]. We'll need to get back to the drawing board with
      that.

      net: dsa: mv88e6xxx: Wait for EEPROM done before HW reset · 23d775f1
      Alfred Lee authored
      If the switch is reset during active EEPROM transactions, as in
      just after an SoC reset after power up, the I2C bus transaction
      may be cut short leaving the EEPROM internal I2C state machine
      in the wrong state.  When the switch is reset again, the bad
      state machine state may result in data being read from the wrong
      memory location causing the switch to enter unexpected mode
      rendering it inoperational.
