      drm/msm: add stubs for msm_{perf,rd}_debugfs_cleanup · 3a270e4d
      Arnd Bergmann authored
      We now call those two functions even when they are not defined
      or declared anywhere because DEBUG_FS is disabled:
      
      drivers/gpu/drm/msm/msm_drv.c: In function 'msm_drm_uninit':
      drivers/gpu/drm/msm/msm_drv.c:244:2: error: implicit declaration of function 'msm_perf_debugfs_cleanup';did you mean 'msm_framebuffer_cleanup'? [-Werror=implicit-function-declaration]
      drivers/gpu/drm/msm/msm_drv.c:245:2: error: implicit declaration of function 'msm_rd_debugfs_cleanup';did you mean 'msm_framebuffer_cleanup'? [-Werror=implicit-function-declaration]
      
      This adds empty stub implementations for that case.

      imx-drm PRE/PRG support, deferred plane disabling, separate alpha support
      
      - Initial support for the Prefetch Resolve Engine/Gasket on i.MX6QP,
        improving linear scanout buffer memory bandwidth utilization. This
        will in the future grow reordering support and allow direct scanout
        of Vivante tiled renderbuffers from the GPU.
      - Deferred plane disabling gets rid of some busy waiting in the atomic
        plane disable and crtc disable paths that lead to wait_for_vblank
        timeouts.
      - Add support for RGBA formats with a separate alpha plane, that can
        reduce memory bandwidth utilization for mostly transparent overlay
        planes by skipping color reads for completely transparent regions.
      - Allow moving an active overlay plane without enforcing a modeset.
      - Add 8-bit and 16-bit bayer formats to ipu_cpmem_set_image.
      - Set the base address in ipu_cpmem_set_image even for invalid formats
        to increase robustness against errors.
      - Use drm_plane_helper_check_state in plane atomic_check.
      - Some cleanup.

      mm/swap: don't BUG_ON() due to uninitialized swap slot cache · 452b94b8
      Linus Torvalds authored
      This BUG_ON() triggered for me once at shutdown, and I don't see a
      reason for the check.  The code correctly checks whether the swap slot
      cache is usable or not, so an uninitialized swap slot cache is not
      actually problematic afaik.
      
      I've temporarily just switched the BUG_ON() to a WARN_ON_ONCE(), since
      I'm not sure why that seemingly pointless check was there.  I suspect
      the real fix is to just remove it entirely, but for now we'll warn about
      it but not bring the machine down.
