      of/irq: Mark initialised interrupt controllers as populated · 15cc2ed6
      Jon Hunter authored
      For interrupt controllers successfully initialised early via device-tree,
      mark these interrupt controllers as populated so we don't unnecessarily
      create a device and populate any platform data later on in the boot
      sequence when we populate all the various platform devices.

      of: fix memory leak related to safe_name() · d9fc8807
      Frank Rowand authored
      Fix a memory leak resulting from memory allocation in safe_name().
      This patch fixes all call sites of safe_name().
      
      Mathieu Malaterre reported the memory leak on boot:
      
      On my PowerMac device-tree would generate a duplicate name:
      
      [    0.023043] device-tree: Duplicate name in PowerPC,G4@0, renamed to "l2-cache#1"
      
      in this case a newly allocated name is generated by `safe_name`. However
      in this case it is never deallocated.
      
      The bug was found using kmemleak reported as:
      
      unreferenced object 0xdf532e60 (size 32):
        comm "swapper", pid 1, jiffies 4294892300 (age 1993.532s)

       "A new bunch of GPIO fixes for v4.7.
      
        This time I am very grateful that Ricardo Ribalda Delgado went in and
        fixed my stupid refcounting mistakes in the removal path for GPIO
        chips.  I had a feeling something was wrong here and so it was.  It
        exploded on OMAP and it fixes their problem.  Now it should be (more)
        solid.
      
        The rest i compilation, Kconfig and driver fixes.  Some tagged for
        stable.
      
        Summary:
      
         - Fix a NULL pointer dereference when we are searching the GPIO
           device list but one of the devices have been removed (struct
           gpio_chip pointer is NULL).
      
         - Fix unaligned reference counters: we were ending on +3 after all
           said and done.  It should be 0.  Remove an extraneous get_device(),
           and call cdev_del() followed by device_del() in gpiochip_remove()
           instead and the count goes to zero and calls the release() function
           properly.
      
         - Fix a compile warning due to a missing #include in the OF/device
           tree portions.
      
         - Select ANON_INODES for GPIOLIB, we're using that for our character
           device.  Some randconfig tests disclosed the problem.
      
         - Make sure the Zynq driver clock runs also without CONFIG_PM enabled
      
         - Fix an off-by-one error in the 104-DIO-48E driver
      
         - Fix warnings in bcm_kona_gpio_reset()"

      Pull SCSI fixes from James Bottomley:
       "Two current fixes:
      
         - one affects Qemu CD ROM emulation, which stopped working after the
           updates in SCSI to require VPD pages from all conformant devices.
      
           Fix temporarily by blacklisting Qemu (we can relax later when they
           come into compliance).
      
         - The other is a fix to the optimal transfer size.  We set up a
           minefield for ourselves by being confused about whether the limits
           are in bytes or sectors (SCSI optimal is in blocks and the queue
           parameter is in bytes).
      
           This tries to fix the problem (wrong setting for queue limits
           max_sectors) and make the problem more obvious by introducing a
           wrapper function"

      sched: panic on corrupted stack end · 29d64551
      Jann Horn authored
      Until now, hitting this BUG_ON caused a recursive oops (because oops
      handling involves do_exit(), which calls into the scheduler, which in
      turn raises an oops), which caused stuff below the stack to be
      overwritten until a panic happened (e.g.  via an oops in interrupt
      context, caused by the overwritten CPU index in the thread_info).
      
      Just panic directly.
