2008-04-19x86: integrate pci-dma.cGlauber Costa
The code in pci-dma_{32,64}.c are now sufficiently close to each other. We merge them in pci-dma.c. Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2008-04-19x86: move bad_dma_addressGlauber Costa
It goes to pci-dma.c, and is removed from the arch-specific files. Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2008-04-19x86: move dma_coherent functions to pci-dma.cGlauber Costa
They are placed in an ifdef, since they are i386 specific the structure definition goes to dma-mapping.h. Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2008-04-19x86: merge iommu initialization parametersGlauber Costa
we merge the iommu initialization parameters in pci-dma.c Nice thing, that both architectures at least recognize the same parameters. usedac i386 parameter is marked for deprecation Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2008-04-19x86: merge dma_supportedGlauber Costa
The code for both arches are very similar, so this patch merge them. Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2008-04-19x86: move pci fixup to pci-dma.cGlauber Costa
via_no_dac provides a fixup that is the same for both architectures. Move it to pci-dma.c. Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2008-04-19x86: move x86_64-specific to common code.Glauber Costa
This patch moves the bootmem functions, that are largely x86_64-specific into pci-dma.c. The code goes inside an ifdef. Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2008-04-19x86: move initialization functions to pci-dma.cGlauber Costa
initcalls that triggers the various possibiities for dma subsys are moved to pci-dma.c. Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2008-04-19x86: unify pci-nommuGlauber Costa
merge pci-base_32.c and pci-nommu_64.c into pci-nommu.c Their code were made the same, so now they can be merged. Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

2008-04-19x86: introduce pci-dma.cGlauber Costa
This patch introduces pci-dma.c, a common file for pci dma between i386 and x86_64. As a start, dma_set_mask() is the same between architectures, and is placed there.
