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

2015-03-12T20:04:01Z

Previously, pci_scan_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_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_bus() and do it after any resource assignment in the callers.

mm: enhance free_reserved_area() to support poisoning memory with zero

2013-07-03T23:07:32Z

Address more review comments from last round of code review. 1) Enhance free_reserved_area() to support poisoning freed memory with pattern '0'. This could be used to get rid of poison_init_mem() on ARM64. 2) A previous patch has disabled memory poison for initmem on s390 by mistake, so restore to the original behavior. 3) Remove redundant PAGE_ALIGN() when calling free_reserved_area().

PCI: Make the struct pci_dev * argument of pci_fixup_irqs const.

2011-07-22T15:26:06Z

Aside of the usual motivation for constification, this function has a history of being abused a hook for interrupt and other fixups so I turned this function const ages ago in the MIPS code but it should be done treewide. Due to function pointer passing in varous places a few other functions had to be constified as well.

alpha: nautilus - fix hang on boot

2009-01-16T00:39:40Z

Recently introduced generic pci_common_swizzle() relies on bus->self being NULL for the root PCI bus. But on nautilus bus->self points to the host bridge device, which is necessary as we do a root bus sizing on this system. As a result, pci_common_swizzle() loops infinitely. This worked until 2.6.29-rc1 because the alpha-specific swizzle routine checked for bus->parent == NULL (instead of bus->self). Fixed by clearing bus->self after bus sizing is done.

alpha: fix legacy mode PCI IDE controllers

2008-04-24T15:35:46Z

Legacy IDE resources were never properly allocated on most alpha platforms, so IDE expectedly stopped working after commit 10f000a2fd805e8ccfe988e8615545467bb7f7df (generic pci_enable_resources). Always allocate "fixed" PCI resources before doing anything else; remove Cypress IDE quirk, as it's a generic problem which is handled in common PCI probe code.
