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.

This fixes parallel (-j) builds and makes it possible to build

This should hold until the real fix arrives.
What is the HPET I hear you ask? It is the High Precision Event Timer
that is supposed to supplement and eventually replace the 8254 timer and
the RTC periodic interrupts. Among other things, it is 64 bit (can be
run in 32 bit mode for 32 bit cpus), and is suitable as a replacement for
the ACPI timer on SMP systems (the specs are much better) and as a
replacement for the ITC based synthetic clock for on ia64 systems.
It seems IA64 and AMD64 systems tend to have this. It is likely to start
showing up in i386 systems if it isn't already on some of them.
* AcpiOsDerivePciId(): finds a bus number, given the slot/func and the
acpi parse tree.
* AcpiOsPredefinedOverride(): use the sysctl hw.acpi.os_name to
override the value for _OS.

o Extend struct ACPIrsdp with the ACPI 2.0 fields which involves
changing a prior reserved field into the ACPI revision,
o Only calculate the RSDP checksum on the first 20 bytes to remain
compatible with ACPI 1.0 tables; we don't check the extended
checksum covering the whole table,
o Use the length field in the RSDP to map the RSDP into the address
space so that we don't have to know about future extensions here.
