John Baldwin 7157eae462 For no good reason I had assumed that ACPI table headers would be page ... aligned (or at least not cross a page boundary). However, it turns out that on at least one machine one table header does cross a page boundary. This caused problems with the MADT early probe as it uses the crash dump map to load ACPI tables by loading the RSDT/XSDT into pages 1 ... N and loading the header of each ACPI table header into page 0 looking for the MADT. However, if a table header crossed a page boundary, then page 1 would get trashed resulting in a panic. Fix this by reserving the first 2 pages for ACPI table headers (headers are less than a page in size, so 2 pages will be sufficient) and use pages 2 .. N for the RSDT and XSDT. Note: amd64 should probably be simplified to just use pmap_mapbios() for all these tables which will use the direct map and not need the crash dump hack.
