      pinctrl: nomadik: nmk_prcm_gpiocr_get_mode may be unused · 0fafd50e
      Arnd Bergmann 提交于
      nmk_prcm_gpiocr_get_mode is only needed for debugfs output at
      the moment, which can be compile-time disabled. Marking
      the function __maybe_unused still gives us compile-time
      coverage, but avoids a gcc warning.
      
      Without this patch, building nhk8815_defconfig results in:

      pinctrl: exynos: don't mark probing functions as __init · 312b00e5
      Arnd Bergmann 提交于
      Functions called from a driver probe() method must not be
      marked __init, because they may get called after the
      init phase is done, when the device shows up late, or
      because of deferred probing.
      
      Without this patch, building exynos_defconfig results in
      multiple warnings like:
      
      WARNING: drivers/pinctrl/built-in.o(.text+0x51bc): Section mismatch in reference from the function exynos5440_pinctrl_probe() to the function .init.text:exynos5440_gpiolib_register()
      The function exynos5440_pinctrl_probe() references
      the function __init exynos5440_gpiolib_register().
      This is often because exynos5440_pinctrl_probe lacks a __init
      annotation or the annotation of exynos5440_gpiolib_register is wrong.

      Tiejun Chen 提交于
      With lazy interrupt, we always call __check_irq_replaysome with
      decrementers_next_tb to check if we need to replay timer interrupt.
      So in hotplug case we also need to set decrementers_next_tb as MAX
      to make sure __check_irq_replay don't replay timer interrupt
      when return as we expect, otherwise we'll trap here infinitely.

      powerpc/pasemi: Fix crash on reboot · 72640d88
      Steven Rostedt 提交于
      commit f96972f2 "kernel/sys.c: call disable_nonboot_cpus() in
      kernel_restart()"
      
      added a call to disable_nonboot_cpus() on kernel_restart(), which tries
      to shutdown all the CPUs except the first one. The issue with the PA
      Semi, is that it does not support CPU hotplug.
      
      When the call is made to __cpu_down(), it calls the notifiers
      CPU_DOWN_PREPARE, and then tries to take the CPU down.
      
      One of the notifiers to the CPU hotplug code, is the cpufreq. The
      DOWN_PREPARE will call __cpufreq_remove_dev() which calls
      cpufreq_driver->exit. The PA Semi exit handler unmaps regions of I/O
      that is used by an interrupt that goes off constantly
      (system_reset_common, but it goes off during normal system operations
      too). I'm not sure exactly what this interrupt does.
      
      Running a simple function trace, you can see it goes off quite a bit:
      
      # tracer: function
      #
      #           TASK-PID    CPU#    TIMESTAMP  FUNCTION

      When the region is unmapped, the system crashes with:

        13) macvlan_get_size() causes underallocation netlink message space,
            fix from Eric Dumazet.
      
        14) Avoid division by zero in xfrm_replay_advance_bmp(), from Nickolai
            Zeldovich.  Amusingly the zero check was already there, we were
            just performing it after the modulus :-)
      
        15) Some more splice bug fixes from Eric Dumazet, which fix things
            mostly eminating from how we now more aggressively use high-order
            pages in SKBs.
      
        16) Fix size calculation bug when freeing hash tables in the IPSEC
            xfrm code, from Michal Kubecek.
      
        17) Fix PMTU event propagation into socket cached routes, from Steffen
            Klassert.
      
        18) Fix off by one in TX buffer release in netxen driver, from Eric
            Dumazet.
      
        19) Fix rediculous memory allocation requirements introduced by the
            tuntap multiqueue changes, from Jason Wang.
      
        20) Remove bogus AMD platform workaround in r8169 driver that causes
            major problems in normal operation, from Timo Teräs.
      
        21) virtio-net set affinity and select queue don't handle
            discontiguous cpu numbers properly, fix from Wanlong Gao.
      
        22) Fix a route refcounting issue in loopback driver, from Eric
            Dumazet.  There's a similar fix coming that we might add to the
            macvlan driver as well.
      
        23) Fix SKB leaks in batman-adv's distributed arp table code, from
            Matthias Schiffer.
      
        24) r8169 driver gives descriptor ownership back the hardware before
            we're done reading the VLAN tag out of it, fix from Francois
            Romieu.
      
        25) Checksums not calculated properly in GRE tunnel driver fix from
            Pravin B Shelar.
      
      26) Fix SCTP memory leak on namespace exit."
