* powerpc/of-bindings: Don't support linux,<modalias> "compatible" valuesGrant Likely2008-10-10
| | | | | | | | | | | | | | Compatible property values in the form linux,<modalias> is not documented anywhere and using it leaks Linux implementation details into the device tree data (which is bad). Remove support for compatible values of this form. If any platforms exist which depended on this code (and I don't know of any), then they can be fixed up by adding legacy translations to the lookup table in this file.

* powerpc: Fix error path in kernel_thread functionJosh Poimboeuf2008-10-10
| | | | | | | | | | | | | | The powerpc 32-bit and 64-bit kernel_thread functions don't properly propagate errors being returned by the clone syscall. (In the case of error, the syscall exit code returns a positive errno in r3 and sets the CR0[SO] bit.) This patch fixes that by negating r3 if CR0[SO] is set after the syscall.

* powerpc/cell/oprofile: Fix test on overlay_tbl_offset in vma_mapRoel Kluin2008-10-10
| | | | | | | | | | | | | | | Offset is unsigned and when an address isn't found in the vma map vma_map_lookup() returns the vma physical address + 0x10000000. vma_map_lookup used to return 0xffffffff on a failed lookup, but a change was made to return the vma physical address + 0x10000000 There are two callers of vam_map_lookup: one of them correctly deals with this new return value, but the other (below) did not.

* powerpc: Fix no interrupt handling in pata_of_platformAnton Vorontsov2008-10-10
| | | | | | | | | | | | | When no interrupt is specified the pata_of_platform fills the irq_res resource with -1, which is wrong to do for two reasons: 1. By definition, 'no irq' should be IRQ 0, not some negative integer; 2. pata_platform checks for irq_res.start > 0, but since irq_res.start is unsigned type, the check will be true for `-1'.

| | | | | | | | | | | | | | Testing hotplug memory remove has revealed that we can oops in pseries_lmb_remove(). The incorrect shift causes a NULL pointer dereference in the page_zone() inline routine. I have only been able to reproduce the oops on kernels with large pages enabled.

* powerpc: Fix sysfs pci mmap on 32-bit machines with 64-bit PCIBenjamin Herrenschmidt2008-10-06
| | | | | | | | | | | | When manipulating 64-bit PCI addresses, the code would lose the top 32-bit in a couple of places when shifting a pfn due to missing type casting from the 32-bit pfn to a 64-bit resource before the shift. This breaks using newer X servers for example on 440 machines with the PCI bus above 32-bit. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

| | | | | | | | | | | | | | rtas_log_read() doesn't check file flags for O_NONBLOCK and blocks non-blocking readers of /proc/ppc64/rtas/error_log when there is no data available. This fixes it.

* powerpc: Enforce sane MAX_ORDERJohannes Berg2008-10-06
| | | | | | | | | | | | | | powerpc uses CONFIG_FORCE_MAX_ZONEORDER, and some things depend on it being at least 10 when 64k pages are not configured (notably the dart iommu code with CONFIG_PM). The defaults are fine, but when going from a 64K pages config to one without 64K pages, MAX_ORDER stays at 9 which is too low for 4K pages. This patch makes the Kconfig enforce at least the defaults.

* powerpc: Avoid integer overflow in page_is_ram()Roland Dreier2008-10-06
| | | | | | | | | | | | | | | | | | | | | | | | | | 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 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 Boyer2008-09-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Bruce2008-09-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Gala2008-09-24
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

These properties connect the SSI nodes to the DMA nodes for the DMA channels that the SSI should use. Also update the ssi.txt documentation. These properties will be needed when the ASoC V2 version of the Freescale MPC8610 device drivers are merged into the mainline.
