      vfio: Fix PCI INTx disable consistency · 899649b7
      Alex Williamson 提交于
      The virq_disabled flag tracks the userspace view of INTx masking
      across interrupt mode changes, but we're not consistently applying
      this to the interrupt and masking handler notion of the device.
      Currently if the user sets DisINTx while in MSI or MSIX mode, then
      returns to INTx mode (ex. rebooting a qemu guest), the hardware has
      DisINTx+, but the management of INTx thinks it's enabled, making it
      impossible to actually clear DisINTx.  Fix this by updating the
      handler state when INTx is re-enabled.

      vfio: Move PCI INTx eventfd setting earlier · 9dbdfd23
      Alex Williamson 提交于
      We need to be ready to recieve an interrupt as soon as we call
      request_irq, so our eventfd context setting needs to be moved
      earlier.  Without this, an interrupt from our device or one
      sharing the interrupt line can pass a NULL into eventfd_signal
      and oops.

      vfio: Fix PCI mmap after b3b9c293 · 34002f54
      Alex Williamson 提交于
      Our mmap path mistakely relied on vma->vm_pgoff to get set in
      remap_pfn_range.  After b3b9c293, that path only applies to
      copy-on-write mappings.  Set it in our own code.

           Aside from the issues discussed at the LKS, distros are shipping
           NFSv4.1 with all the trimmings.
         - Fix fdatasync()/fsync() for the corner case of a server reboot.
         - NFSv4 OPEN access fix: finally distinguish correctly between
           open-for-read and open-for-execute permissions in all situations.
         - Ensure that the TCP socket is closed when we're in CLOSE_WAIT
         - More idmapper bugfixes
         - Lots of pNFS bugfixes and cleanups to remove unnecessary state and
           make the code easier to read.
         - In cases where a pNFS read or write fails, allow the client to
           resume trying layoutgets after two minutes of read/write-
           through-mds.
         - More net namespace fixes to the NFSv4 callback code.
         - More net namespace fixes to the NFSv3 locking code.
         - More NFSv4 migration preparatory patches.
           Including patches to detect network trunking in both NFSv4 and
           NFSv4.1
         - pNFS block updates to optimise LAYOUTGET calls."

      Linus Torvalds 提交于
      Pull pwm changes from Thierry Reding:
       "All legacy PWM providers have now been moved to the PWM subsystem.
        The plan for 3.8 is to adapt all board files to provide a lookup table
        for PWM devices in order to get rid of the global namespace.
        Subsequently, users of the legacy pwm_request() and pwm_free()
        functions can be migrated to the new pwm_get() and pwm_put()
        functions.  Once this has been completed, the legacy API and the
        compatibility code in the core can be removed.
      
        In addition to the above, these changes also add support for
        configuring the polarity of a PWM signal (currently only supported on
        ECAP and EHRPWM) and include a much needed rework of the i.MX driver.
        Managed functions to obtain and release a PWM device (devm_pwm_get()
        and devm_pwm_put()) have been added and the pwm-backlight driver has
        been updated to use them.  If the PWM subsystem hasn't been enabled,
        dummy functions are provided that allow the subsystem to safely
        compile out.
      
        Some common checks on input parameters have been moved to the core and
        removed from the drivers.  Finally, a small fix corrects the
        description of the PWM specifier's second cell in the device tree
        representation."
