      [ARM] 3024/1: Add cpu_v6_proc_fin · 67c5587a

      Patch from Tony Lindgren
      
      Machine restart calls cpu_proc_fin() to clean and disable
      cache, and turn off interrupts. This patch adds proper
      cpu_v6_proc_fin.

      [PATCH] Handle spurious page fault for hugetlb region · 3359b54c
      Seth, Rohit authored
      
      
      The hugetlb pages are currently pre-faulted.  At the time of mmap of
      hugepages, we populate the new PTEs.  It is possible that HW has already
      cached some of the unused PTEs internally.  These stale entries never
      get a chance to be purged in existing control flow.
      
      This patch extends the check in page fault code for hugepages.  Check if
      a faulted address falls with in size for the hugetlb file backing it.
      We return VM_FAULT_MINOR for these cases (assuming that the arch
      specific page-faulting code purges the stale entry for the archs that
      need it).

      [ This is apparently arguably an ia64 port bug. But the code won't
        hurt, and for now it fixes a real problem on some ia64 machines ]
