Subject: vmalloc_32 should use GFP_KERNEL
From: Benjamin Herrenschmidt <[EMAIL PROTECTED]>
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.
