vmalloc_32 should use GFP_KERNEL
I've noticed lots of failures of vmalloc_32 on machines where it shouldn't have failed unless it was doing an atomic operation. Looking closely, I noticed that: #if defined(CONFIG_64BIT) && defined(CONFIG_ZONE_DMA32) #define GFP_VMALLOC32 GFP_DMA32 #elif defined(CONFIG_64BIT) && defined(CONFIG_ZONE_DMA) #define GFP_VMALLOC32 GFP_DMA #else #define GFP_VMALLOC32 GFP_KERNEL #endif Which seems to be incorrect, it should always -or- in the DMA flags on top of GFP_KERNEL, thus this patch. This fixes frequent errors launchin X with the nouveau DRM for example.
