      Revert "fsnotify: fix oops in fsnotify_clear_marks_by_group_flags()" · d725e66c
      Linus Torvalds 提交于
      This reverts commit a2673b6e.
      
      Kinglong Mee reports a memory leak with that patch, and Jan Kara confirms:
      
       "Thanks for report! You are right that my patch introduces a race
        between fsnotify kthread and fsnotify_destroy_group() which can result
        in leaking inotify event on group destruction.
      
        I haven't yet decided whether the right fix is not to queue events for
        dying notification group (as that is pointless anyway) or whether we
        should just fix the original problem differently...  Whenever I look
        at fsnotify code mark handling I get lost in the maze of locks, lists,
        and subtle differences between how different notification systems
        handle notification marks :( I'll think about it over night"
      
      and after thinking about it, Jan says:
      
       "OK, I have looked into the code some more and I found another
        relatively simple way of fixing the original oops.  It will be IMHO
        better than trying to fixup this issue which has more potential for
        breakage.  I'll ask Linus to revert the fsnotify fix he already merged
        and send a new fix"

       "Here are some overly ripe pin control fixes for the v4.2 series.
      
        They got delayed because of various crap commits and having to clean

        good.
      
         - some dead defines dropped from the Samsung driver, was targeted for
           -rc2 but got delayed
         - drop the strict mode from abx500, this was too strict
         - fix the R-Car sparse IRQs code to work as intended
         - fix the IRQ code for the pinctrl-single GPIO backend to not enforce
           threaded IRQs
         - clear the latched events/IRQs for the Broadcom BCM2835 driver
         - fix up debugfs for the Freescale imx1 driver
         - fix a typo bug in the Schmitt Trigger setup in the LPC18xx driver"

      s390: adapt entry.S to the move of thread_struct · 3827ec3d
      Martin Schwidefsky 提交于
      git commit 0c8c0f03
      "x86/fpu, sched: Dynamically allocate 'struct fpu'"
      moved the thread_struct to the end of the task_struct.
      
      This causes some of the offsets used in entry.S to overflow their
      instruction operand field. To fix this  use aghi to create a
      dedicated pointer for the thread_struct.

      AVR32/time: Migrate to new 'set-state' interface · 09adcdf2
      Viresh Kumar 提交于
      Migrate avr32 driver to the new 'set-state' interface provided by
      clockevents core, the earlier 'set-mode' interface is marked obsolete
      now.
      
      This also enables us to implement callbacks for new states of clockevent
      devices, for example: ONESHOT_STOPPED.
      
      We want to call cpu_idle_poll_ctrl() in shutdown only if we were in
      oneshot or resume state earlier. Create another variable to save this
      information and check that in shutdown callback.

      Subject: pinctrl: imx1-core: Fix debug output in .pin_config_set callback · 9571b25d
      Uwe Kleine-König 提交于
      imx1_pinconf_set assumes that the array of pins in struct
      imx1_pinctrl_soc_info can be indexed by pin id to get the
      pinctrl_pin_desc for a pin. This used to be correct up to commit
      607af165 which removed some entries from the array and so made it
      wrong to access the array by pin id.
      
      The result of this bug is a wrong pin name in the output for small pin
      ids and an oops for the bigger ones.
      
      This patch is the result of a discussion that includes patches by Markus
      Pargmann and Chris Ruehl.

      pinctrl: bcm2835: Clear the event latch register when disabling interrupts · 714b1dd8
      Jonathan Bell 提交于
      It's possible to hit a race condition if interrupts are generated on a GPIO
      pin when the IRQ line in question is being disabled.
      
      If the interrupt is freed, bcm2835_gpio_irq_disable() is called which
      disables the event generation sources (edge, level). If an event occurred
      between the last disabling of hard IRQs and the write to the event
      source registers, a bit would be set in the GPIO event detect register
      (GPEDSn) which goes unacknowledged by bcm2835_gpio_irq_handler()
      so Linux complains loudly.
      
      There is no per-GPIO mask register, so when disabling GPIO interrupts
      write 1 to the relevant bit in GPEDSn to clear out any stale events.

      pinctrl: single: ensure pcs irq will not be forced threaded · c10372e6

      The PSC IRQ is requested using request_irq() API and as result it can

      sh-pfc: fix sparse GPIOs for R-Car SoCs · 61bb3aef
      Sergei Shtylyov 提交于
      The PFC driver causes the kernel to hang on the R-Car gen2 SoC based  boards
      when the CPU_ALL_PORT() macro is fixed to reflect the reality, i.e. when the
      GPIO space becomes actually sparse.  This happens because the _GP_GPIO() macro
      includes  an indexed initializer which causes the "holes" (array entries filled
      with all 0s) between the groups  of the existing GPIOs; and the driver can't
      cope with that.  There seems to  be no reason to use the indexed initializer,
      so we can remove the index specifier and so avoid the "holes".

      pinctrl: abx500: remove strict mode · 27aa2e3a
      Linus Walleij 提交于
      Commit a21763a0
      "pinctrl: nomadik: activate strict mux mode"
      put all Nomadik pin controllers to strict mode. This was
      not good on the Snowball platform: the muxing of GPIOs to
      different pins is done with hogs in the DTS file, and then
      these GPIOs are used by offset, relying on hogs to mux the
      pins. Since that means the pin controller "owns" the pins
      and at the same time we have a GPIO user, this pin controller
      is by definition not strict.

      added support for 64-bit FPU on a 32-bit MIPS R6 processor but it missed
      the 64-bit CPU case leading to FPU failures when requesting FR=1 mode
      (which is always the case for MIPS R6 userland) when running a 32-bit
      kernel on a 64-bit CPU. We also fix the MIPS R2 case.

      After this commit, the 'return' statement in pmd_free is executed in all
      cases. Even for pmd that are not attached to the pgd.  So 'free_pages'
      can never be called anymore, leading to a memory leak.

       "Two families of fixes:
      
         - Fix an FPU context related boot crash on newer x86 hardware with
           larger context sizes than what most people test.  To fix this
           without ugly kludges or extensive reverts we had to touch core task
           allocator, to allow x86 to determine the task size dynamically, at
           boot time.
      
           I've tested it on a number of x86 platforms, and I cross-built it
           to a handful of architectures:
      
                                              (warns)               (warns)
