[PATCH] sort the devres mess out * 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.

[POWERPC] devres: Add devm_ioremap_prot() We provide an ioremap_flags, so this provides a corresponding devm_ioremap_prot. The slight name difference is at Ben Herrenschmidt's request as he plans on changing ioremap_flags to ioremap_prot in the future.

[PATCH] pci_iomap_regions() error handling fix 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.
