      apparmor: fix regression in mount mediation when feature set is pinned · 5b9f57cf
      John Johansen authored
      When the mount code was refactored for Labels it was not correctly
      updated to check whether policy supported mediation of the mount
      class.  This causes a regression when the kernel feature set is
      reported as supporting mount and policy is pinned to a feature set
      that does not support mount mediation.

       "Another small stash of fixes for fallout from the PTI work:
      
         - Fix the modules vs. KASAN breakage which was caused by making
           MODULES_END depend of the fixmap size. That was done when the cpu
           entry area moved into the fixmap, but now that we have a separate
           map space for that this is causing more issues than it solves.
      
         - Use the proper cache flush methods for the debugstore buffers as
           they are mapped/unmapped during runtime and not statically mapped
           at boot time like the rest of the cpu entry area.
      
         - Make the map layout of the cpu_entry_area consistent for 4 and 5
           level paging and fix the KASLR vaddr_end wreckage.
      
         - Use PER_CPU_EXPORT for per cpu variable and while at it unbreak
           nvidia gfx drivers by dropping the GPL export. The subject line of
           the commit tells it the other way around, but I noticed that too
           late.
      
         - Fix the ASM alternative macros so they can be used in the middle of
           an inline asm block.
      
         - Rename the BUG_CPU_INSECURE flag to BUG_CPU_MELTDOWN so the attack

      and
      
      Warning (unit_address_format): Node /XXX unit name should not have leading 0s
      
      Converted using the following command:
      
      find . -type f \( -iname *.dts -o -iname *.dtsi \) -exec sed -i -e "s/@\([0-9a-fA-FxX\.;:#]+\)\s*{/@\L\1 {/g" -e "s/@0x\(.*\) {/@\1 {/g" -e "s/@0+\(.*\) {/@\1 {/g" {} +^C
      
      For simplicity, two sed expressions were used to solve each warnings separately.
      
      To make the regex expression more robust a few other issues were resolved,
      namely setting unit-address to lower case, and adding a whitespace before the
      the opening curly brace:
      
      https://elinux.org/Device_Tree_Linux#Linux_conventions

      mfd: rtsx: Release IRQ during shutdown · 107b7d9f
      Sinan Kaya authored
      'Commit cc27b735 ("PCI/portdrv: Turn off PCIe services during

      Even though rtsx_pci driver implements a shutdown callback, it is not
      releasing the interrupt that it registered during probe. This is causing
      the ACPI layer to complain that the shared IRQ is in use while freeing
      IRQ.
      
      This code releases the IRQ to prevent resource leak and eliminate the
      warning.

      ARM: dts: kirkwood: fix pin-muxing of MPP7 on OpenBlocks A7 · 56aeb07c
      Thomas Petazzoni authored
      MPP7 is currently muxed as "gpio", but this function doesn't exist for
      MPP7, only "gpo" is available. This causes the following error:
      
      kirkwood-pinctrl f1010000.pin-controller: unsupported function gpio on pin mpp7
      pinctrl core: failed to register map default (6): invalid type given
      kirkwood-pinctrl f1010000.pin-controller: error claiming hogs: -22
      kirkwood-pinctrl f1010000.pin-controller: could not claim hogs: -22
      kirkwood-pinctrl f1010000.pin-controller: unable to register pinctrl driver
      kirkwood-pinctrl: probe of f1010000.pin-controller failed with error -22
      
      So the pinctrl driver is not probed, all device drivers (including the
      UART driver) do a -EPROBE_DEFER, and therefore the system doesn't
      really boot (well, it boots, but with no UART, and no devices that
      require pin-muxing).
      
      Back when the Device Tree file for this board was introduced, the
      definition was already wrong. The pinctrl driver also always described
      as "gpo" this function for MPP7. However, between Linux 4.10 and 4.11,
      a hog pin failing to be muxed was turned from a simple warning to a
      hard error that caused the entire pinctrl driver probe to bail
      out. This is probably the result of commit 61187142 ("pinctrl:
      core: Fix pinctrl_register_and_init() with pinctrl_enable()").
      
      This commit fixes the Device Tree to use the proper "gpo" function for
      MPP7, which fixes the boot of OpenBlocks A7, which was broken since
      Linux 4.11.

      Pull drm fixes from Dave Airlie:
       "Just collecting some fixes to finish my hoildays :-).
      
        A few fixes for i915 (one documentation build fix), one ttm fix, one
        AMD display fix, one omapdrm fix, and a set of armada fixes from
        Russell.
      
        All seem pretty small, you can now return to your latest security news
        site"
