      commit: e9eafcb5 [1/2] drm: move drm_can_sleep() to drm_util.h

         arch/ia64/include/asm/pal.h: In function 'ia64_pal_tr_read':
         arch/ia64/include/asm/pal.h:1703:64: error: implicit declaration of function 'ia64_tpa'; did you mean 'ia64_pal'?  [-Werror=implicit-function-declaration]

                                                                         ^~~~~~~~
      ...
      
      So we have a situation where we do not pull in <linux/types.h>
      when building for alpha and for ia64 we need even more definitions
      are required.
      
      Two invasive fixes where considered:
      - Change all declarations of arch_irqs_disabled_flags() to use bool
      - Add include of <linux/types.h> to all files that uses bool for
        arch_irqs_disabled_flags
      
      To invasive with a too high pain/benefit ratio, so dropped.
      They would not cover ia64 either.
      
      Some less invasive fixes was also considered:
      - Add include of <linux/types.h> to drm_util.h
      - Add include of <linux/interrupt.h> to drm_util.h
      
      The first was dropped as this did not cover the ia64 case.
      
      The latter was considered the best option as there could
      be other similar cases and we would like the header files below
      include/drm/ to be selfcontained.
      So we end up pulling in a lot of stuff not needed, but this is
      the price we pay in drm/ because the kernel headers are not all
      selfcontained.
      
      While at it, ordred the includefiles in drm_util in alphabetical order.
      
      Build tested with alpha,ia64,arm,x86 with allmodconfig and allyesconfig.
      
      v2:
      - fix ia64 build, changed to include interrupt.h
      - sort include files alphabetically

      dt-bindings: panel: Add missing .txt suffix · 993a815d

      All other files in that directory have a .txt suffix, so add one for
      consistency.
