X-Git-Tag: v2.6.31-rc6~15^2~6 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=51b89f7a6615eca184aa0b85db5781d931e9c8d1;p=pandora-kernel.git Bug Fix arch/ia64/kernel/pci-dma.c: fix recursive dma_supported() call in iommu_dma_supported() In commit 160c1d8e40866edfeae7d68816b7005d70acf391, dma_ops->dma_supported = iommu_dma_supported; This dma_ops->dma_supported is first called in platform_dma_init() during kernel boot. Then dma_ops->dma_supported will be called recursively in iommu_dma_supported. Kernel can not boot because kernel can not get out of iommu_dma_supported until it runs out of stack memory.
