      [PATCH] x86-64: Only look at per_cpu data for online cpus. · 70a0a535
      Eric W. Biederman authored
      
      
      When I generalized __assign_irq_vector I failed to pay attention
      to what happens when you access a per cpu data structure for
      a cpu that is not online.   It is an undefined case making any
      code that does it have undefined behavior as well.
      
      The code still needs to be able to allocate a vector across cpus
      that are not online to properly handle combinations like lowest
      priority interrupt delivery and cpu_hotplug.  Not that we can do
      that today but the infrastructure shouldn't prevent it.
      
      So this patch updates the places where we touch per cpu data
      to only touch online cpus, it makes cpu vector allocation
      an atomic operation with respect to cpu hotplug, and it updates
      the cpu start code to properly initialize vector_irq so we
      don't have inconsistencies.

      [PATCH] x86-64: Simplify the vector allocator. · d1752aa8
      Eric W. Biederman authored
      
      
      There is no reason to remember a per cpu position of which vector
      to try.  Keeping a global position is simpler and more likely to
      result in a global vector allocation even if I don't need or require
      it.  For level triggered interrupts this means we are less likely to
      acknowledge another cpus irq, and cause the level triggered irq to
      harmlessly refire.
      
      This simplification makes it easier to only access data structures
      of  online cpus, by having fewer special cases to deal with.

      [ARM] Comment out missing configuration symbols · 52f0c673
      Russell King authored
      
      
      HAS_TOUCHSCREEN_ADS7843_LH7 and HAS_TOUCHSCREEN_ADC_LH7 are referenced
      but not defined in the LH7A40x configuration.  Comment them out to
      prevent them causing warnings.

         Feel free to remove the Kconfig lines.  I'll add it back with
         the rest of the config entries.
