      efi/arm64: Fix debugfs crash by adding a terminator for ptdump marker · 74c953ca
      Qian Cai authored
      When reading 'efi_page_tables' debugfs triggers an out-of-bounds access here:
      
        arch/arm64/mm/dump.c: 282
        if (addr >= st->marker[1].start_address) {
      
      called from:
      
        arch/arm64/mm/dump.c: 331
        note_page(st, addr, 2, pud_val(pud));
      
      because st->marker++ is is called after "UEFI runtime end" which is the
      last element in addr_marker[]. Therefore, add a terminator like the one
      for kernel_page_tables, so it can be skipped to print out non-existent
      markers.
      
      Here's the KASAN bug report:

      x86/resctrl: Avoid confusion over the new X86_RESCTRL config · e6d42931
      Johannes Weiner authored
      "Resource Control" is a very broad term for this CPU feature, and a term
      that is also associated with containers, cgroups etc. This can easily
      cause confusion.
      
      Make the user prompt more specific. Match the config symbol name.
      
       [ bp: In the future, the corresponding ARM arch-specific code will be
         under ARM_CPU_RESCTRL and the arch-agnostic bits will be carved out
         under the CPU_RESCTRL umbrella symbol. ]
