  dma-mapping: reject GFP_COMP for noncoherent allocations (2022-12-21 08:45:38 +0100)

----------------------------------------------------------------
dma-mapping fixes for Linux 6.2

Fix up the sound code to not pass __GFP_COMP to the non-coherent DMA
allocator, as it copes with that just as badly as the coherent allocator,
and then add a check to make sure no one passes the flag ever again.

----------------------------------------------------------------
Christoph Hellwig (2):
      ALSA: memalloc: don't use GFP_COMP for non-coherent dma allocations
      dma-mapping: reject GFP_COMP for noncoherent allocations
