      iomap: make the default iomap functions fail softer · 6cbf0c70
      Linus Torvalds 提交于
      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.

      [PATCH] sort the devres mess out · 5ea81769
      Al Viro 提交于
      * 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.

      devres: implement pcim_iomap_regions() · d24bbbf2
      Tejun Heo 提交于
      Implement pcim_iomap_regions().  This function takes mask of BARs to
      request and iomap.  No BAR should have length of zero.  BARs are
      iomapped using pcim_iomap_table().

      devres: device resource management · 9ac7849e
      Tejun Heo 提交于
      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()

      [PATCH] add Big Endian variants of ioread/iowrite · dae409a2
      James Bottomley 提交于
      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).

      Linux-2.6.12-rc2 · 1da177e4
      Linus Torvalds 提交于
      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!
