FUJITA Tomonori f405d2c023 x86/agp: Fix agp_amd64_init() initialization with CONFIG_GART_IOMMU enabled with CONFIG_GART_IOMMU enabled drivers/char/agp/amd64-agp.c has: #ifndef CONFIG_GART_IOMMU module_init(agp_amd64_init); module_exit(agp_amd64_cleanup); #endif agp_amd64_init() was called via gart_iommu_init with CONFIG_GART_IOMMU=y agp_amd64_init() was called via module_init with CONFIG_GART_IOMMU=n The commit `75f1cdf1dd` changes the x86 dma initialization routine: gart_iommu_init() is called only when GART IOMMU is detected. So when GART IOMMU isn't detected, agp_amd64_init isn't called. Marin Mitov reported this issue: http://marc.info/?l=linux-kernel&m=126192729110083&w=2 With this patch, agp_amd64_init() is always called via module_init (the above ifndef is removed). If agp_amd64_init() is called via gart_iommu_init() earlier, agp_amd64_init() finishes without doing anything (when it is called via module_init).
