The 'report_error' interface for PCI devices found on s390 can be used by a user space program to inject an adapter error notification. Add a new kernel interface zpci_report_error to allow a PCI device driver to inject these error notifications without a detour over user space.

The dma-mapping core and the implementations do not change the DMA attributes passed by pointer. Thus the pointer can point to const data. However the attributes do not have to be a bitfield. Instead unsigned long will do fine: 1. This is just simpler. Both in terms of reading the code and setting attributes. Instead of initializing local attributes on the stack and passing pointer to it to dma_set_attr(), just set the bits. 2. It brings safeness and checking for const correctness because the attributes are passed by value. Semantic patches for this change (at least most of them): virtual patch virtual context @r@ identifier f, attrs; @@ f(..., - struct dma_attrs *attrs + unsigned long attrs , ...) { ... } @@ identifier r.f; @@ f(..., - NULL + 0 ) and // Options: --all-includes virtual patch virtual context @r@ identifier f, attrs; type t; @@ t f(..., struct dma_attrs *attrs); @@ identifier r.f; @@ f(..., - NULL + 0 ) Link: http://lkml.kernel.org/r/1468399300-5399-2-git-send-email-k.kozlowski@samsung.comSigned-off-by: NKrzysztof Kozlowski <k.kozlowski@samsung.com> Acked-by: NVineet Gupta <vgupta@synopsys.com> Acked-by: NRobin Murphy <robin.murphy@arm.com> Acked-by: NHans-Christian Noren Egtvedt <egtvedt@samfundet.no> Acked-by: Mark Salter <msalter@redhat.com> [c6x] Acked-by: Jesper Nilsson <jesper.nilsson@axis.com> [cris] Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> [drm] Reviewed-by: NBart Van Assche <bart.vanassche@sandisk.com> Acked-by: Joerg Roedel <jroedel@suse.de> [iommu] Acked-by: Fabien Dessenne <fabien.dessenne@st.com> [bdisp] Reviewed-by: Marek Szyprowski <m.szyprowski@samsung.com> [vb2-core] Acked-by: David Vrabel <david.vrabel@citrix.com> [xen] Acked-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com> [xen swiotlb] Acked-by: Joerg Roedel <jroedel@suse.de> [iommu] Acked-by: Richard Kuo <rkuo@codeaurora.org> [hexagon] Acked-by: Geert Uytterhoeven <geert@linux-m68k.org> [m68k] Acked-by: Gerald Schaefer <gerald.schaefer@de.ibm.com> [s390] Acked-by: NBjorn Andersson <bjorn.andersson@linaro.org> Acked-by: Hans-Christian Noren Egtvedt <egtvedt@samfundet.no> [avr32] Acked-by: Vineet Gupta <vgupta@synopsys.com> [arc] Acked-by: Robin Murphy <robin.murphy@arm.com> [arm64 and dma-iommu] Signed-off-by: NAndrew Morton <akpm@linux-foundation.org> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

When we use the iommu_area_alloc helper to get dma addresses we specify the boundary_size parameter but not the offset (called shift in this context). As long as the offset (start_dma) is a multiple of the boundary we're ok (on current machines start_dma always seems to be 4GB).

As virtio-ccw will have dma ops, we can no longer default to the zPCI ones. Make use of dev_archdata to keep the dma_ops per device. The pci devices now use that to override the default, and the default is changed to use the noop ops for everything that does not specify a device specific one.

For each PCI function we need to maintain arch specific data in struct zpci_dev which also contains a pointer to struct pci_dev. When a function is registered or deregistered (which is triggered by PCI common code) we need to adjust that pointer which could interfere with the machine check handler (triggered by FW) using zpci_dev->pdev. Since multiple instances of the same pdev could exist at a time this can't be solved with locking. Fix that by ditching the pdev pointer and use a bus walk to reach struct pci_dev (only one instance of a pdev can be registered at the bus at a time).

On s390 we need to maintain a mapping between iomem addresses and arch specific function identifiers. Currently the mapping table is created as such that we could span the whole iomem address space. Since we can only map each bar space from each possible function we have an upper bound for the number of mapping entries.

DMA addresses returned from map_page() are calculated by using an iommu bitmap plus a start_dma offset. The size of this bitmap is based on the main memory size. If we have more than (4 TB - start_dma) main memory, the DMA address calculation will also produce addresses > 4 TB. Such addresses cannot be inserted in the 3-level DMA page table, instead the entries modulo 4 TB will be overwritten. Fix this by restricting the iommu bitmap size to (4 TB - start_dma). Also set zdev->end_dma to the actual end address of the usable range, instead of the theoretical maximum as reported by the hardware, which fixes a sanity check in dma_map() and also the IOMMU API domain geometry aperture calculation.

Almost everyone implements dma_set_mask the same way, although some time that's hidden in ->set_dma_mask methods. This patch consolidates those into a common implementation that either calls ->set_dma_mask if present or otherwise uses the default implementation. Some architectures used to only call ->set_dma_mask after the initial checks, and those instance have been fixed to do the full work. h8300 implemented dma_set_mask bogusly as a no-ops and has been fixed. Unfortunately some architectures overload unrelated semantics like changing the dma_ops into it so we still need to allow for an architecture override for now.

Previously, pci_scan_root_bus() created a root PCI bus, enumerated the devices on it, and called pci_bus_add_devices(), which made the devices available for drivers to claim them. Most callers assigned resources to devices after pci_scan_root_bus() returns, which may be after drivers have claimed the devices. This is incorrect; the PCI core should not change device resources while a driver is managing the device. Remove pci_bus_add_devices() from pci_scan_root_bus() and do it after any resource assignment in the callers. Note that ARM's pci_common_init_dev() already called pci_bus_add_devices() after pci_scan_root_bus(), so we only need to remove the first call: pci_common_init_dev pcibios_init_hw pci_scan_root_bus pci_bus_add_devices # first call pci_bus_assign_resources pci_bus_add_devices # second call [bhelgaas: changelog, drop "root_bus" var in alpha common_init_pci(), return failure earlier in mn10300, add "return" in x86 pcibios_scan_root(), return early if xtensa platform_pcibios_fixup() fails] Signed-off-by: NYijing Wang <wangyijing@huawei.com> Signed-off-by: NBjorn Helgaas <bhelgaas@google.com> CC: Richard Henderson <rth@twiddle.net> CC: Ivan Kokshaysky <ink@jurassic.park.msu.ru> CC: Matt Turner <mattst88@gmail.com> CC: David Howells <dhowells@redhat.com> CC: Tony Luck <tony.luck@intel.com> CC: Michal Simek <monstr@monstr.eu> CC: Ralf Baechle <ralf@linux-mips.org> CC: Koichi Yasutake <yasutake.koichi@jp.panasonic.com> CC: Sebastian Ott <sebott@linux.vnet.ibm.com> CC: "David S.
