the PCI routing handling, and getting the Joliet stuff right for iso9660.

- final:
    - Patrick Mochel: export the ACPI facs table in /proc too
    - Brian Gerst: Video4Linux cleanup (named initializers)
    - Linus: only use irq13 for FP errors for external FPU's. This
      fixes the Atlon FP exception lockups.
    - Linus: add a new intel signature to the PIRQ table matching logic.
      Make the matching match both reported and actual device ID (with a
      preference for the reported). Fixes PCMCIA on NEC Versa laptops.
    - iso9660: fix Joliet filename argument order bug introduced in pre7
    - Highmem: p_page -> b_page typo.
    - Linus: don't allow pending FPU exceptions without an FPU context..
