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().
