PCI: Remove pci_get_legacy_ide_irq() and asm-generic/pci.h pci_get_legacy_ide_irq() is only used on platforms that support PNP, so many architectures define it but never use it. Replace uses of it with ATA_PRIMARY_IRQ() and ATA_SECONDARY_IRQ(), which provide the same functionality. Since pci_get_legacy_ide_irq() is no longer used, remove all the architecture-specific definitions of it as well as asm-generic/pci.h, which only provides pci_get_legacy_ide_irq() [bhelgaas: commit log] Co-developed-by: Arnd Bergmann <arnd@arndb.de> Link: https://lore.kernel.org/r/20220722214944.831438-2-shorne@gmail.com Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Stafford Horne <shorne@gmail.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Reviewed-by: Christoph Hellwig <hch@lst.de> Acked-by: Geert Uytterhoeven <geert@linux-m68k.org> Acked-by: Pierre Morel <pmorel@linux.ibm.com> Acked-by: Rafael J.

PCI: remove PCI_DMA_BUS_IS_PHYS This was used by the ide, scsi and networking code in the past to determine if they should bounce payloads. Now that the dma mapping always have to support dma to all physical memory (thanks to swiotlb for non-iommu systems) there is no need to this crude hack any more.

xtensa/PCI: Use generic pci_mmap_resource_range() Commit f719582435 ("PCI: Add pci_mmap_resource_range() and use it for ARM64") added this generic function with the intent of using it everywhere and ultimately killing the old arch-specific implementations. Remove the xtensa-specific pci_mmap_page_range() and use the generic pci_mmap_resource_range() instead. Xtensa can mmap I/O port space, so supply the xtensa-specific pci_iobar_pfn() required to make that work.

PCI: Move pci_dma_* helpers to common code For a long time all architectures implement the pci_dma_* functions using the generic DMA API, and they all use the same header to do so. Move this header, pci-dma-compat.h, to include/linux and include it from the generic pci.h instead of having each arch duplicate this include.

PCI: Xtensa: convert pcibios_set_master() to a non-inlined function This patch converts Xtensa's architecture-specific 'pcibios_set_master()' routine to a non-inlined function. This will allow follow on patches to create a generic 'pcibios_set_master()' function using the '__weak' attribute which can be used by all architectures as a default which, if necessary, can then be over- ridden by architecture-specific code. Converting 'pci_bios_set_master()' to a non-inlined function will allow Xtensa's 'pcibios_set_master()' implementation to remain architecture-specific after the generic version is introduced and thus, not change current behavior. No functional change. Signed-off-by: Myron Stowe <myron.stowe@redhat.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
