      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: fix C1E && nx6325 stability problem · e2079c43
      Rafael J. Wysocki authored
      The problems are that, with the ACPI vs timer overring issue _fixed_,
      after using the box for some time (between several seconds and 1 hour, at
      random) processes get very high CPU loads (once I've got X using 107% of
      the CPU, for example) and the system becomes unresponsive, as though there
      were interrupts lost or something similar.
      
      Andreas Herrman reproduced similar problems:

      So lets fall back to the IRQ0/INT0 configuration on this box.
      
      This basically restores the dont-use-the-lapic-timer exception mechanism
      that was unconditional on this box prior commit 8750bf5 ("x86: add C1E
      aware idle function").

      [PATCH] i386: Allow to use GENERICARCH for UP kernels · 874c4fe3
      Andi Kleen authored
      There are some machines around (large xSeries or Unisys ES7000) that
      need physical IO-APIC destination mode to access all of their IO
      devices. This currently doesn't work in UP kernels as used in
      distribution installers.
      
      This patch allows to compile even UP kernels as GENERICARCH which
      allows to use physical or clustered APIC mode.

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
