Use WARN() instead of a printk+WARN_ON() pair; this way the message becomes part of the warning section for better reporting/collection. In addition, one of the if() clauses collapes into the WARN() entirely now.

Almost all implementations of pci_iomap() in the kernel, including the generic lib/iomap.c one, copies the content of a struct resource into unsigned long's which will break on 32 bits platforms with 64 bits resources. This fixes all definitions of pci_iomap() to use resource_size_t. I also "fixed" the 64bits arch for consistency.

It appears that 64-bit PCI resources cannot possibly ever have worked on x86-32 even when the RESOURCES_64BIT config option was set, because any driver that tried to [pci_]ioremap() the resource would have been unable to do so because the high 32 bits would have been silently dropped on the floor by the ioremap() routines that only used "unsigned long". Change them to use "resource_size_t" instead, which properly encodes the whole 64-bit resource data if RESOURCES_64BIT is enabled. Acked-by: NH.

We used to BUG_ON() for a badly mapped IO port, which is certainly correct, but actually made it harder to debug the case where the ATA drivers had incorrectly mapped a nonconnected ATA port. So make badly mapped ports trigger a WARN_ON(), and throw the IO away instead (and return all ones for reads). For things like broken driver initialization - which is the most likely cause anyway - that should mean that the machine comes up and is usable (at least that was the case for the ATA breakage that triggered this patch). It tends to be a whole lot easier to do a "dmesg" on a working machine than to try to capture logs off a dead one. Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

* 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.

Implement device resource management, in short, devres. A device driver can allocate arbirary size of devres data which is associated with a release function. On driver detach, release function is invoked on the devres data, then, devres data is freed. devreses are typed by associated release functions. Some devreses are better represented by single instance of the type while others need multiple instances sharing the same release function. Both usages are supported. devreses can be grouped using devres group such that a device driver can easily release acquired resources halfway through initialization or selectively release resources (e.g. resources for port 1 out of 4 ports). This patch adds devres core including documentation and the following managed interfaces. * alloc/free : devm_kzalloc(), devm_kzfree() * IO region : devm_request_region(), devm_release_region() * IRQ : devm_request_irq(), devm_free_irq() * DMA : dmam_alloc_coherent(), dmam_free_coherent(), dmam_declare_coherent_memory(), dmam_pool_create(), dmam_pool_destroy() * PCI : pcim_enable_device(), pcim_pin_device(), pci_is_managed() * iomap : devm_ioport_map(), devm_ioport_unmap(), devm_ioremap(), devm_ioremap_nocache(), devm_iounmap(), pcim_iomap_table(), pcim_iomap(), pcim_iounmap() Signed-off-by: NTejun Heo <htejun@gmail.com> Signed-off-by: NJeff Garzik <jeff@garzik.org>

In the new io infrastructure, all of our operators are expecting the underlying device to be little endian (because the PCI bus, their main consumer, is LE). However, there are a fair few devices and busses in the world that are actually Big Endian. There's even evidence that some of these BE bus and chip types are attached to LE systems. Thus, there's a need for a BE equivalent of our io{read,write}{16,32} operations. The attached patch adds this as io{read,write}{16,32}be. When it's in, I'll add the first consume (the 53c700 SCSI chip driver).

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
