      x86: consolidate header guards · 77ef50a5
      Vegard Nossum authored
      This patch is the result of an automatic script that consolidates the
      format of all the headers in include/asm-x86/.
      
      The format:
      
      1. No leading underscore. Names with leading underscores are reserved.
      2. Pathname components are separated by two underscores. So we can
         distinguish between mm_types.h and mm/types.h.
      3. Everything except letters and numbers are turned into single
         underscores.

      x86: i386-show-unhandled-signals-v3 · abd4f750
      Masoud Asgharifard Sharbiani authored
      This patch makes the i386 behave the same way that x86_64 does when a
      segfault happens.  A line gets printed to the kernel log so that tools
      that need to check for failures can behave more uniformly between
      debug.show_unhandled_signals sysctl variable to 0 (or by doing echo 0 >
      /proc/sys/debug/exception-trace)
      
      Also, all of the lines being printed are now using printk_ratelimit() to
      deny the ability of DoS from a local user with a program like the
      following:
      
      main()
      {
             while (1)
                     if (!fork()) *(int *)0 = 0;
      }
      
      This new revision also includes the fix that Andrew did which got rid of
      new sysctl that was added to the system in earlier versions of this.
      Also, 'show-unhandled-signals' sysctl has been renamed back to the old
      'exception-trace' to avoid breakage of people's scripts.
      
      AK: Enabling by default for i386 will be likely controversal, but let's see what happens
      AK: Really folks, before complaining just fix your segfaults
      AK: I bet this will find a lot of silent issues

      x86_64: disable the GART in shutdown · bc2cea6a
      Yinghai Lu authored
      For K8 system: 4G RAM with memory hole remapping enabled, or more than 4G
      RAM installed.  when using kexec to load second kernel.  In the second
      kernel, when mem is allocated for GART, it will do the memset for clear, it
      will cause restart, because some device still used that for dma.  solution
      will be:
      
      in second kernel: disable that at first before we try to allocate mem for
      it.  or in the first kernel: do disable that before shutdown.
      Andi/Eric/Alan prefer to second one for clean shutdown in first kernel.
      Andi also point out need to consider to AGP enable but mem less 4G case
      too.

      But adds:

      The warnings does not show up during a normal build due to kbuild
      failing to check for section mismatch in vmlinux.
      To see these warnings run:
      scripts/mod/modpost arch/x86_64/kernel/built-in.o
      
      kbuild will be fixed but the 'noise-level' had to be decresed first.
      There remains a few section mismatch warnigns for x86_64 for areas where I did
      not feel confident.
