2009-09-17MIPS: Don't corrupt page tables on vmalloc fault.David Daney
The code after the vmalloc_fault: label in do_page_fault() modifies user page tables, this is not correct for 64-bit kernels. For 64-bit kernels we should go straight to the no_context handler skipping vmalloc_fault. Signed-off-by: David Daney <ddaney@caviumnetworks.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2009-09-17MIPS: Shrink the size of tlb handlerWu Fei
By combining swapper_pg_dir and module_pg_dir, several if conditions can be eliminated from the tlb exception handler. The reason they can be combined is that, the effective virtual address of vmalloc returned is at the bottom, and of module_alloc returned is at the top. It also fixes the bug in vmalloc(), which happens when its return address is not covered by the first pgd. Signed-off-by: Wu Fei <at.wufei@gmail.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

This allows the callers to now pass down the full set of FAULT_FLAG_xyz flags to handle_mm_fault().

2009-05-20MIPS: 64-bit: Fix system lockup.Greg Ungerer
The address range size calculation inside local_flush_tlb_kernel_range() is being truncated by a too small size variable holder on 64-bit systems. The truncated size can result in an erroneous tlbsize check that means we sit spinning inside a loop trying to flush a hige number of TLB entries. This is for all intents and purposes a system hang. Fix by using an appropriately sized valiable to hold the size. [Ralf: Greg's original patch submission identified the issue and fixed one instance in tlb-r4k.c but there there were several more. For consistency I also modified tlb-r3k.c even though that file is only used on 32-bit.] Signed-off-by: Greg Ungerer <gerg@snapgear.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

This patch removes the various CPU_AU1??? model constants in favor of a single CPU_ALCHEMY one. All currently existing Alchemy models are identical in terms of cpu core and cache size/organization. The parts of the mips kernel which need to know the exact CPU revision extract it from the c0_prid register already; and finally nothing else in-tree depends on those any more. Should a new variant with slightly different "company options" and/or "processor revision" bits in c0_prid appear, it will be supported immediately (minus an exact model string in cpuinfo).

2009-03-11MIPS: NEC VR5500 processor support fixupShinya Kuribayashi
Current VR5500 processor support lacks of some functions which are expected to be configured/synthesized on arch initialization. Here're some VR5500A spec notes: * All execution hazards are handled in hardware. * Once VR5500A stops the operation of the pipeline by WAIT instruction, it could return from the standby mode only when either a reset, NMI request, or all enabled interrupts is/are detected. In other words, if interrupts are disabled by Status.IE=0, it keeps in standby mode even when interrupts are internally asserted. Notes on WAIT: The operation of the processor is undefined if WAIT insn is in the branch delay slot. The operation is also undefined if WAIT insn is executed when Status.EXL and Status.ERL are set to 1. * VR5500A core only implements the Load prefetch. With these changes, it boots fine.

2008-07-26dma-mapping: add the device argument to dma_mapping_error()FUJITA Tomonori
Add per-device dma_mapping_ops support for CONFIG_X86_64 as POWER architecture does: This enables us to cleanly fix the Calgary IOMMU issue that some devices are not behind the IOMMU (http://lkml.org/lkml/2008/5/8/423). I think that per-device dma_mapping_ops support would be also helpful for KVM people to support PCI passthrough but Andi thinks that this makes it difficult to support the PCI passthrough (see the above thread). So I CC'ed this to KVM camp. Comments are appreciated. A pointer to dma_mapping_ops to struct dev_archdata is added. If the pointer is non NULL, DMA operations in asm/dma-mapping.h use it. If it's NULL, the system-wide dma_ops pointer is used as before. If it's useful for KVM people, I plan to implement a mechanism to register a hook called when a new pci (or dma capable) device is created (it works with hot plugging). It enables IOMMUs to set up an appropriate dma_mapping_ops per device. The major obstacle is that dma_mapping_error doesn't take a pointer to the device unlike other DMA operations. So x86 can't have dma_mapping_ops per device. Note all the POWER IOMMUs use the same dma_mapping_error function so this is not a problem for POWER but x86 IOMMUs use different dma_mapping_error functions. The first patch adds the device argument to dma_mapping_error. The patch is trivial but large since it touches lots of drivers and dma-mapping.h in all the architecture. This patch: dma_mapping_error() doesn't take a pointer to the device unlike other DMA operations. So we can't have dma_mapping_ops per device. Note that POWER already has dma_mapping_ops per device but all the POWER IOMMUs use the same dma_mapping_error function. x86 IOMMUs use device argument.
