x86: change early_gart_iommu_check() back to any_mapped
Kevin Winchester reported a GART related direct rendering failure against linux-next-20080611, which shows up via these log entries: PCI: Using ACPI for IRQ routing PCI: Cannot allocate resource region 0 of device 0000:00:00.0 agpgart: Detected AGP bridge 0 agpgart: Aperture conflicts with PCI mapping. agpgart: Aperture from AGP @ e0000000 size 128 MB agpgart: Aperture conflicts with PCI mapping. agpgart: No usable aperture found. agpgart: Consider rebooting with iommu=memaper=2 to get a good aperture. instead of the expected: PCI: Using ACPI for IRQ routing agpgart: Detected AGP bridge 0 agpgart: Aperture from AGP @ e0000000 size 128 MB Kevin bisected it down to this change in tip/x86/gart: "x86: checking aperture size order". agp check is using request_mem_region(), and could fail if e820 is reserved... change it back to e820_any_mapped().
