devres: implement pcim_iomap_regions_request_all()

2008-03-17T12:26:44Z

Some drivers need to reserve all PCI BARs to prevent other drivers misusing unoccupied BARs. pcim_iomap_regions_request_all() requests all BARs and iomap specified BARs. Signed-off-by: Tejun Heo Cc: Greg Kroah-Hartman Cc: Alan Cox Cc: Jeff Garzik Signed-off-by: Jeff Garzik

[PATCH] pci_iomap_regions() error handling fix

2007-02-16T16:13:55Z

It appears that the pcim_iomap_regions() function doesn't get the error handling right. It BUGs early at boot with a backtrace along the lines of: ahci_init pci_register_driver driver_register [...] ahci_init_one pcim_iomap_region pcim_iounmap The following patch allows me to boot. Only the if(mask..) continue; part fixes the problem actually, the gotos where changed so that we don't try to unmap something we couldn't map anyway.

[PATCH] sort the devres mess out

2007-02-11T19:18:07Z

* Split the implementation-agnostic stuff in separate files. * Make sure that targets using non-default request_irq() pull kernel/irq/devres.o * Introduce new symbols (HAS_IOPORT and HAS_IOMEM) defaulting to positive; allow architectures to turn them off (we needed these symbols anyway for dependencies of quite a few drivers). * protect the ioport-related parts of lib/devres.o with CONFIG_HAS_IOPORT.
