fredette 94791afd65 No longer use BTLB entries to map the entire address spaces of I/O subsystems, ... since BTLB entries can be scarce and very little of an I/O subsystem normally needs to be mapped. Instead, the pmap now allows mappings of I/O space to be entered with pmap_kenter_pa. bus_space mappings for small amounts of I/O space (as for virtually all devices) are made this way, with BTLB entries still used for large mappings for things like framebuffers. This has led to more and cleaned-up uses of bus_space(9) and has caused some autoconf cleanup. Also, kgdb is now attached and connected before autoconfiguration, which is much earlier than before.		2002-08-25 20:19:59 +00:00
