Modified files:
usr.sbin/acpi/acpidump acpi_user.c acpidump.h
Log:
Instead of scanning the entire lower 1 MB of RAM, only scan locations
where the RSD PTR can actually occur. According to section 5.2.2
of the ACPI spec, we only consider two regions for the base address:
1. EBDA (0x0 - 0x3FF)
2. High memory (0xE0000 - 0xFFFFF)
I don't know whether this fixes any actual problems but is more correct.
