      percpu: fix first chunk match in per_cpu_ptr_to_phys() · 9983b6f0
      Tejun Heo 提交于
      per_cpu_ptr_to_phys() determines whether the passed in @addr belongs
      to the first_chunk or not by just matching the address against the
      address range of the base unit (unit0, used by cpu0).  When an adress
      from another cpu was passed in, it will always determine that the
      address doesn't belong to the first chunk even when it does.  This
      makes the function return a bogus physical address which may lead to
      crash.
      
      This problem was discovered by Cliff Wickman while investigating a
      crash during kdump on a SGI UV system.
