      proc_sysctl: fix oops caused by incorrect command parameters · 697edcb0
      Xiaoming Ni authored
      The process_sysctl_arg() does not check whether val is empty before
      invoking strlen(val).  If the command line parameter () is incorrectly
      configured and val is empty, oops is triggered.
      
      For example:
        "hung_task_panic=1" is incorrectly written as "hung_task_panic", oops is
        triggered. The call stack is as follows:
          Kernel command line: .... hung_task_panic
          ......
          Call trace:
          __pi_strlen+0x10/0x98
          parse_args+0x278/0x344
          do_sysctl_args+0x8c/0xfc
          kernel_init+0x5c/0xf4
          ret_from_fork+0x10/0x30
      
      To fix it, check whether "val" is empty when "phram" is a sysctl field.
      Error codes are returned in the failure branch, and error logs are
      generated by parse_args().

      powerpc/mm/highmem: use __set_pte_at() for kmap_local() · 78502582
      Thomas Gleixner authored
      The original PowerPC highmem mapping function used __set_pte_at() to
      denote that the mapping is per CPU.  This got lost with the conversion
      to the generic implementation.
      
      Override the default map function.
