* In the boot blocks, stop assuming we have a 1:1 mapping of low physicalmiod2010-06-2914-574/+1221
| | | | | | | | | | | | | | | | | | | | | | memory, but instead gather memory layout information and work with the MMU (or the PROM) to make sure we can actually load the kernel image in a proper contiguous physical memory area. In order to do this, we look at the kernel image twice; during the first pass, the kernel footprint is computed, and then after making sure it can be loaded, the second pass loads the actual image. Since such a logic doesn't work on media which can not seek backwards, such as tapes, we check for the boot device being a tape and, in that case, assume a fixed (generous) image size and don't load the kernel symbol table (to avoid seeking backwards); since tape boot is supposed to be only used to boot bsd.rd, this is something we can live with. While there, lower the address the boot blocks are loaded in memory, because the last crank did not work with some early sun4c OpenPROM, which only map about 3.5MB of memory. Memory games logic from NetBSD, tape handling by me.

| | | | | | | | max-baud-rate hint. Adjust TTYHOG (the nearly full logic) to this new situation. The larger buffers are required by the very high speed KDDI devices in Japan (CF com, or USB ucom) so those are the only two drivers which currently ask for a larger buffer size. ok yasuoka miod

| | | | | | | | | | | | | | | | | | | | | | which contains the constraints for DMA/memory allocation for each architecture, and dma_constraints which contains the range of addresses that are dma accessable by the system. This is based on ariane@'s physcontig diff, with lots of bugfixes and additions the following additions by my self: Introduce a new function pool_set_constraints() which sets the address range for which we allocate pages for the pool from, this is now used for the mbuf/mbuf cluster pools to keep them dma accessible. The !direct archs no longer stuff pages into the kernel object in uvm_km_getpage_pla but rather do a pmap_extract() in uvm_km_putpages. Tested heavily by my self on i386, amd64 and sparc64.
