I have just confirmed that pasting
#define GFP_DMA32 ((__force gfp_t)0x04u)
into /alsa-kernel/pci/emu10k1/memory.c (not a correct fix -just taken from 2.6.24 headers) enables build to complete. So there should be no other hidden issues.
Could you try attached patch (also pasted bellow)?
That's too overhead. A simple #ifndef GFP_DMA32 would work. And, GFP_DMA32 isn't GFP_DMA.
But old kernels with dma_mask < 0xffffffff sets GFP_DMA flag for page allocation. So there's no regression.
GFP_DMA32 means to allocate from ZONE_DMA32 which was a part of ZONE_NORMAL.
