      drm/gma500: Fix BUG: sleeping function called from invalid context errors · 63e37a79
      Hans de Goede authored
      gma_crtc_page_flip() was holding the event_lock spinlock while calling
      crtc_funcs->mode_set_base() which takes ww_mutex.
      
      The only reason to hold event_lock is to clear gma_crtc->page_flip_event
      on mode_set_base() errors.
      
      Instead unlock it after setting gma_crtc->page_flip_event and on
      errors re-take the lock and clear gma_crtc->page_flip_event it
      it is still set.
      
      This fixes the following WARN/stacktrace:

      drm/meson: Fix OSD1 RGB to YCbCr coefficient · 6463d393
      Stuart Menefy authored
      VPP_WRAP_OSD1_MATRIX_COEF22.Coeff22 is documented as being bits 0-12,
      not 16-28.
      
      Without this the output tends to have a pink hue, changing it results
      in better color accuracy.
      
      The vendor kernel doesn't use this register. However the code which
      sets VIU2_OSD1_MATRIX_COEF22 also uses bits 0-12. There is a slightly
      different style of registers for configuring some of the other matrices,
      which do use bits 16-28 for this coefficient, but those have names
      ending in MATRIX_COEF22_30, and this is not one of those.

      drm/meson: Correct OSD1 global alpha value · 6836829c

      VIU_OSD1_CTRL_STAT.GLOBAL_ALPHA is a 9 bit field, so the maximum

      afs: Enable multipage folio support · 8549a263
      David Howells authored
      Enable multipage folio support for the afs filesystem.
      
      Support has already been implemented in netfslib, fscache and cachefiles
      and in most of afs, but I've waited for Matthew Wilcox's latest folio
      changes.
      
      Note that it does require a change to afs_write_begin() to return the
      correct subpage.  This is a "temporary" change as we're working on
      getting rid of the need for ->write_begin() and ->write_end()
      completely, at least as far as network filesystems are concerned - but
      it doesn't prevent afs from making use of the capability.
