* powerpc: Avoid integer overflow in page_is_ram()Roland Dreier2008-10-071-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | Commit 8b150478 ("ppc: make phys_mem_access_prot() work with pfns instead of addresses") fixed page_is_ram() in arch/ppc to avoid overflow for addresses above 4G on 32-bit kernels. However arch/powerpc's page_is_ram() is missing the same fix -- it computes a physical address by doing pfn << PAGE_SHIFT, which overflows if pfn corresponds to a page above 4G. In particular this causes pages above 4G to be mapped with the wrong caching attribute; for example many ppc440-based SoCs have PCI space above 4G, and mmap()ing MMIO space may end up with a mapping that has caching enabled. Fix this by working with the pfn and avoiding the conversion to physical address that causes the overflow. This patch compares the pfn to max_pfn, which is a semantic change from the old code -- that code compared the physical address to high_memory, which corresponds to max_low_pfn. However, I think that was is another bug, since highmem pages are still RAM.

| | | | | | | | | | | | | | | | | | | | | | | | | | The Arches Evaluation board is based on the AMCC 460GT SoC chip. This board is a dual processor board with each processor providing independent resources for Rapid IO, Gigabit Ethernet, and serial communications. Each 460GT has it's own 512MB DDR2 memory, 32MB NOR FLASH, UART, EEPROM and temperature sensor, along with a shared debug port. The two 460GT's will communicate with each other via shared memory, Gigabit Ethernet and x1 PCI-Express.

| * ibm_newemac: MAL support for PowerPC 405EZJosh Boyer2008-09-302-5/+62
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The PowerPC 405EZ SoC has some differences in the interrupt layout and handling for the MAL. The SERR, TXDE, and RXDE interrupts are OR'd into a single interrupt. Also, due to the possibility for interrupt coalescing, the TXEOB and RXEOB interrupts require an interrupt bit to be cleared in the ICINTSTAT SDR. This sets the proper MAL feature bits for 405EZ boards, and adds a common shared handler for SERR, TXDE, and RXDE. The defines for the ICINTSTAT DCR are added to the proper header file as well. This has been adapted from code originally written by Stefan Roese.

| * ibm_newemac: Introduce mal_has_featureJosh Boyer2008-09-302-0/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are some PowerPC SoCs that do odd things with the MAL handling. In order to accommodate them, we need to introduce a feature mechanism that is similar to the existing emac_has_feature function. This adds a feature variable to the mal_instance structure, and adds a mal_has_feature function. Two features are defined and are guarded by Kconfig options that are selected by the affected platforms. MAL_FTR_CLEAR_ICINSTAT is used for platforms that need to clear the interrupt bits in the ICINTSTAT SDR for txeob/rxeob. This is common on MAL implementations that have interrupt coalescing. MAL_FTR_COMMON_ERR_INT is used for platforms that have SERR, TXDE, and RXDE OR'd into a single interrupt bit.

| * | POWERPC: Allow 32-bit hashed pgtable code to support 36-bit physicalBecky Bruce2008-09-2410-33/+109
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This rearranges a bit of code, and adds support for 36-bit physical addressing for configs that use a hashed page table. The 36b physical support is not enabled by default on any config - it must be explicitly enabled via the config system. This patch *only* expands the page table code to accomodate large physical addresses on 32-bit systems and enables the PHYS_64BIT config option for 86xx. It does *not* allow you to boot a board with more than about 3.5GB of RAM - for that, SWIOTLB support is also required (and coming soon).

| * | powerpc: Introduce local (non-broadcast) forms of tlb invalidatesKumar Gala2008-09-244-5/+72
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduced a new set of low level tlb invalidate functions that do not broadcast invalidates on the bus: _tlbil_all - invalidate all _tlbil_pid - invalidate based on process id (or mm context) _tlbil_va - invalidate based on virtual address (ea + pid) On non-SMP configs _tlbil_all should be functionally equivalent to _tlbia and _tlbil_va should be functionally equivalent to _tlbie. The intent of this change is to handle SMP based invalidates via IPIs instead of broadcasts as the mechanism scales better for larger number of cores. On e500 (fsl-booke mmu) based cores move to using MMUCSR for invalidate alls and tlbsx/tlbwe for invalidate virtual address. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We essentially adopt the 64-bit dma code, with some changes to support 32-bit systems, including HIGHMEM. dma functions on 32-bit are now invoked via accessor functions which call the correct op for a device based on archdata dma_ops. If there is no archdata dma_ops, this defaults to dma_direct_ops. In addition, the dma_map/unmap_page functions are added to dma_ops because we can't just fall back on map/unmap_single when HIGHMEM is enabled. In the case of dma_direct_*, we stop using map/unmap_single and just use the page version - this saves a lot of ugly ifdeffing. We leave map/unmap_single in the dma_ops definition, though, because they are needed by the iommu code, which does not implement map/unmap_page. Ideally, going forward, we will completely eliminate map/unmap_single and just have map/unmap_page, if it's workable for 64-bit.
