      arm64: delete __cpuinit usage from all users · b8c6453a
      Paul Gortmaker authored
      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.
      
      Note that some harmless section mismatch warnings may result, since
      notify_cpu_starting() and cpu_up() are arch independent (kernel/cpu.c)
      are flagged as __cpuinit  -- so if we remove the __cpuinit from
      arch specific callers, we will also get section mismatch warnings.
      As an intermediate step, we intend to turn the linux/init.h cpuinit
      content into no-ops as early as possible, since that will get rid
      of these warnings.  In any case, they are temporary and harmless.
      
      This removes all the arch/arm64 uses of the __cpuinit macros from
      all C files.  Currently arm64 does not have any __CPUINIT used in
      assembly files.

      clocksource: arch_timer: use virtual counters · 0d651e4e
      Mark Rutland authored
      
      
      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: convert arm/arm64 arch timer to use CLKSRC_OF init · 0583fe47
      Rob Herring authored
      
      
      This converts arm and arm64 to use CLKSRC_OF DT based initialization for
      the arch timer. A new function arch_timer_arch_init is added to allow for
      arch specific setup.
      
      This has a side effect of enabling sched_clock on omap5 and exynos5. There
      should not be any reason not to use the arch timers for sched_clock.
