      clocksource+irqchip: delete __cpuinit usage from all related files · 8c37bb3a
      Paul Gortmaker 提交于
      The __cpuinit type of throwaway sections might have made sense
      some time ago when RAM was more constrained, but now the savings
      do not offset the cost and complications.  For example, the fix in
      commit 5e427ec2 ("x86: Fix bit corruption at CPU resume time")
      is a good example of the nasty type of bugs that can be created
      with improper use of the various __init prefixes.
      
      After a discussion on LKML[1] it was decided that cpuinit should go
      the way of devinit and be phased out.  Once all the users are gone,
      we can then finally remove the macros themselves from linux/init.h.
      
      This removes all the drivers/clocksource and drivers/irqchip uses of
      the __cpuinit macros from all C files.

      clocksource: arm_global_timer: Add ARM global timer support · c1b40e44
      Stuart Menefy 提交于
      This is a simple driver for the global timer module found in the Cortex
      A9-MP cores from revision r1p0 onwards. This should be able to perform
      the functions of the system timer and the local timer in an SMP system.
      
      The global timer has the following features:
          The global timer is a 64-bit incrementing counter with an
      auto-incrementing feature. It continues incrementing after sending
      interrupts. The global timer is memory mapped in the private memory
      region.
          The global timer is accessible to all Cortex-A9 processors in the
      cluster. Each Cortex-A9 processor has a private 64-bit comparator that
      is used to assert a private interrupt when the global timer has reached
      the comparator value. All the Cortex-A9 processors in a design use the
      banked ID, ID27, for this interrupt. ID27 is sent to the Interrupt
      Controller as a Private Peripheral Interrupt. The global timer is
      clocked by PERIPHCLK.

      clocksource: arch_timer: use virtual counters · 0d651e4e
      Mark Rutland 提交于
      Switching between reading the virtual or physical counters is
      problematic, as some core code wants a view of time before we're fully
      set up. Using a function pointer and switching the source after the
      first read can make time appear to go backwards, and having a check in
      the read function is an unfortunate block on what we want to be a fast
      path.
      
      Instead, this patch makes us always use the virtual counters. If we're a
      guest, or don't have hyp mode, we'll use the virtual timers, and as such
      don't care about CNTVOFF as long as it doesn't change in such a way as
      to make time appear to travel backwards. As the guest will use the
      virtual timers, a (potential) KVM host must use the physical timers
      (which can wake up the host even if they fire while a guest is
      executing), and hence a host must have CNTVOFF set to zero so as to have
      a consistent view of time between the physical timers and virtual
      counters.

      ARM: nomadik: fix clocksource warning · 3c09f4da
      Arnd Bergmann 提交于
      The clocksource API has changed slightly, which causes a harmless
      warning:
      
      /git/arm-soc/drivers/clocksource/nomadik-mtu.c:259:28: warning: 'nmdk_timer_match' defined but not used [-Wunused-variable]
       static struct of_device_id nmdk_timer_match[] __initconst = {
                                  ^
      
      Fortunately, the same API change also lets us simplify the code
      while removing the warning.
