      Driver core: Add support for compatibility classes · 46227094
      Jean Delvare authored
      When turning class devices into bus devices, we may need to
      temporarily add links in sysfs so that user-space applications
      are not confused. This is done by adding the following API:
      
      * Functions to register and unregister compatibility classes.
        These appear in sysfs at the same location as regular classes, but
        instead of class devices, they contain links to bus devices.
      * Functions to create and delete such links. Additionally, the caller
        can optionally pass a target device to which a "device" link should
        point (typically that would be the device's parent), to fully emulate
        the original class device.
      
      The i2c subsystem will be the first user of this API, as i2c adapters
      are being converted from class devices to bus devices.

      uio: add generic driver for PCI 2.3 devices · ccb86a69
      Michael S. Tsirkin authored
      This adds a generic uio driver that can bind to any PCI device.  First
      user will be virtualization where a qemu userspace process needs to give
      guest OS access to the device.
      
      Interrupts are handled using the Interrupt Disable bit in the PCI
      command register and Interrupt Status bit in the PCI status register.
      All devices compliant to PCI 2.3 (circa 2002) and all compliant PCI
      Express devices should support these bits.  Driver detects this support,
      and won't bind to devices which do not support the Interrupt Disable Bit
      in the command register.
      
      It's expected that more features of interest to virtualization will be
      added to this driver in the future. Possibilities are: mmap for device
      resources, MSI/MSI-X, eventfd (to interface with kvm), iommu.

      mem_class: fix bug · 162dd421
      Jin Dongming authored
      When I build and boot -next on fedora 10, I can not login anymore.
      When I input the user name and password, the system does not output
      any message and requires user to input the user name and password
      again and again.
      
      I find the patch which caused this problem with "GIT BISECT" command.
      And the patch is
          commit 7c4b7daa1878972ed0137c95f23569124bd6e2b1
          "mem_class: use minor as index instead of searching the array".
      
      Though I don't know the real reason why user could not login, I
      confirmed the patch I made as following could resolve the problem on
      fedora 10.

      Greg Kroah-Hartman authored
      No one should directly access the driver_data field, so remove the field
      and make it private.  We dynamically create the private field now if it
      is needed, to handle drivers that call get/set before they are
      registered with the driver core.
      
      Also update the copyright notices on these files while we are there.

      Driver core: add new device to bus's list before probing · 2023c610
      Alan Stern authored
      This patch (as1271) affects when new devices get linked into their
      bus's list of devices.  Currently this happens after probing, and it
      doesn't happen at all if probing fails.  Clearly this is wrong,
      because at that point quite a few symbolic links have already been
      created in sysfs.  We are committed to adding the device, so it should
      be linked into the bus's list regardless.
      
      In addition, this needs to happen before the uevent announcing the new
      device gets issued.  Otherwise user programs might try to access the
      device before it has been added to the bus.
      
      To fix both these problems, the patch moves the call to
      klist_add_tail() forward from bus_attach_device() to bus_add_device().
      Since bus_attach_device() now does nothing but probe for drivers, it
      has been renamed to bus_probe_device().  And lastly, the kerneldoc is
      updated.

      When it is build without CONFIG_SECURITY_SELINUX.  This is harmless, but
      the function should be inlined, so it gets compiled out.

      fix undefined reference to user_shm_unlock · 2195d281
      Hugh Dickins authored
      My 353d5c30 "mm: fix hugetlb bug due to
      user_shm_unlock call" broke the CONFIG_SYSVIPC !CONFIG_MMU build of both
      2.6.31 and 2.6.30.6: "undefined reference to `user_shm_unlock'".
      
      gcc didn't understand my comment! so couldn't figure out to optimize
      away user_shm_unlock() from the error path in the hugetlb-less case, as
      it does elsewhere.  Help it to do so, in a language it understands.

      cleanup console_print() · 353f6dd2
      Anirban Sinha authored
      console_print() is an old legacy interface mostly unused in the entire
      kernel tree. It's best to clean up its existing use and let developers
      use their own implementation of it as they feel fit.
