treewide: replace obsolete _refok by __ref

2016-08-02T21:31:41Z

There was only one use of __initdata_refok and __exit_refok __init_refok was used 46 times against 82 for __ref. Those definitions are obsolete since commit 312b1485fb50 ("Introduce new section reference annotations tags: __ref, __refdata, __refconst") This patch removes the following compatibility definitions and replaces them treewide. /* compatibility defines */ #define __init_refok __ref #define __initdata_refok __refdata #define __exit_refok __ref I can also provide separate patches if necessary. (One patch per tree and check in 1 month or 2 to remove old definitions) [akpm@linux-foundation.org: coding-style fixes] Link: http://lkml.kernel.org/r/1466796271-3043-1-git-send-email-fabf@skynet.be Signed-off-by: Fabian Frederick Cc: Ingo Molnar Cc: Sam Ravnborg Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

PCI: Remove unused "pci_probe" flags

2015-07-27T22:09:40Z

The following flags are only used on x86, but they got copied to FR-V, MN10300, and SuperH: PCI_PROBE_BIOS PCI_PROBE_CONF1 PCI_PROBE_CONF2 PCI_ASSIGN_ROMS PCI_NO_CHECKS PCI_BIOS_IRQ_SCAN PCI_ASSIGN_ALL_BUSSES FR-V and MN10300 do test for PCI_ASSIGN_ROMS, but they never set it, so it's dead code. Remove the unused flags above. Signed-off-by: Bjorn Helgaas

PCI: Remove unnecessary #includes of

In include/linux/pci.h, we already #include , so we don't need to include directly. Remove the unnecessary includes. All the files here already include . Signed-off-by: Bjorn Helgaas Acked-by: Simon Horman # sh Acked-by: Ralf Baechle

PCI: Assign resources before drivers claim devices (pci_scan_root_bus())

2015-03-19T15:17:13Z

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: Yijing Wang Signed-off-by: Bjorn Helgaas CC: Richard Henderson CC: Ivan Kokshaysky CC: Matt Turner CC: David Howells CC: Tony Luck CC: Michal Simek CC: Ralf Baechle CC: Koichi Yasutake CC: Sebastian Ott CC: "David S.

sh/PCI: Pass GAPSPCI_DMA_BASE CPU & bus address to dma_declare_coherent_memory()

2014-05-20T22:55:39Z

dma_declare_coherent_memory() needs both the CPU physical address and the bus address of the device memory. They are the same on this platform, but in general we should use pcibios_resource_to_bus() to account for any address translation done by the PCI host bridge. This makes no difference on Dreamcast, but is safer if the usage is copied to future drivers. Signed-off-by: Bjorn Helgaas Acked-by: Arnd Bergmann CC: Magnus Damm CC: linux-sh@vger.kernel.org

sh/PCI: Use default pcibios_enable_device()

We don't need anything arch-specific in pcibios_enable_device(), so drop the arch implementation and use the default generic one. Signed-off-by: Bjorn Helgaas CC: Paul Mundt CC: linux-sh@vger.kernel.org

PCI: Delay enabling bridges until they're needed

2013-07-25T18:35:03Z

We currently enable PCI bridges after scanning a bus and assigning resources. This is often done in arch code. This patch changes this so we don't enable a bridge until necessary, i.e., until we enable a PCI device behind the bridge. We do this in the generic pci_enable_device() path, so this also removes the arch-specific code to enable bridges. [bhelgaas: changelog] Signed-off-by: Yinghai Lu Signed-off-by: Bjorn Helgaas

async: rename and redefine async_func_ptr

2013-03-12T20:59:14Z

A function type is typically defined as typedef ret_type (*func)(args..) but async_func_ptr is not. Redefine it. Also rename async_func_ptr to async_func_t for _func_t suffix is more generic. Signed-off-by: Lai Jiangshan Signed-off-by: Tejun Heo Cc: Arjan van de Ven
