Log Message:
Rework of kernel I/O & memory mappings along with new implementation of
bus_space_map for PCI memory.
The mapping of system devices and I/O space has been shuffled to place them
at the top of memory leaving a larger contiguous chunk between the kernel
itself and the I/O mappings for the kernel VM area. This allows support
for kernel VM areas > 48MB.
The 144MB fixed mapping of early PCI memory space has been removed and a
new version of the bus_space_map() function has been implemented to map
PCI memory into the kernel VM area as required rather than using the fixed
mapping.
A mapping of the first 1MB of PCI memory is maintained for ISA memory
accesses and accesses to the VGA memory.
