13f8dc981f make the cache access latency a parameter that is based on bus
ticks for the most commonly accessed devices.

dev/baddev.cc:
    Get rid of the constant cache access latency.
    For unimportant devices, don't add any latency.

dev/ns_gige.cc:
    The ethernet dev uses two BARs, and the first bars size was being set
    incorrectly.
dev/tsunamireg.h:
    I don't know why we were using the superpage as the PCI memory addr.
    Changed and works correctly with detailed boot.

dev/pciconfigall.hh:
    Added doxygen comments. Made the hlist of devices private and provided
    members to modify the data.
dev/pcidev.cc:
    updated for change in pciconfigall
dev/tsunami_pchip.cc:
    Deleted commented out code we don't need
kern/linux/linux_syscalls.cc:
    Simplified the number -> name conversion.
kern/linux/linux_syscalls.hh:
    Removed StandardNumber and replaced with Number.
kern/linux/linux_system.cc:
kern/linux/linux_system.hh:
    LinuxSkipIdeDelay50msEvent was simply the same as the SkipFunc event,
    so I removed it. Same with with LinuxSkipFuncEvent.

3bfb59f70d Changes to fix bad DMA handling by disk when using scatter gather page
mappings (writes still unverified, and read could probably be looked over
a bit more too)

dev/ide_disk.cc:
dev/ide_disk.hh:
    Major changes to fix bogus handling of dma transfers.  The read seems to
    work pretty well, but the write is unverfied until we can get a disk
    image that actually tries to write.
dev/tsunami_pchip.cc:
    Change mask to properly mask 13 bits not 12

4a5dcc37bf Whole mess'o'changes.. see individual files
arch/alpha/vtophys.cc:
    Removed buggy code that tries to fix PAL addresses (may cause problems
    while trying to debug in PAL code, but that should do this fix outside
    of vtophys)

kern/linux/linux_system.cc:
    Force simulator to wait until remote debugger attaches (should be removed
    or turned on/off with a flag)
