Delete the ability to build an ACPI kernel that does
not include PCI support. When such a machine is created
and it requires a tuned kernel, send a patch.

Current acpi_register_gsi() function has no way to indicate errors to its
callers even though acpi_register_gsi() can fail to register gsi because of
some reasons (out of memory, lack of interrupt vectors, incorrect BIOS, and so
on). As a result, caller of acpi_register_gsi() cannot handle the case that
acpi_register_gsi() fails. I think failure of acpi_register_gsi() should be
handled properly.
This series of patches changes acpi_register_gsi() to return negative value on
error, and also changes callers of acpi_register_gsi() to handle failure of
acpi_register_gsi().
This patch changes the type of return value of acpi_register_gsi() from
"unsigned int" to "int" to indicate an error. If acpi_register_gsi() fails to
register gsi, it returns negative value.

This patch is the first step in properly handling the MCFG PCI table.
It defines the structures properly, and saves off the table so that the
pci mmconfig code can access it. It moves the parsing of the table a
little later in the boot process, but still before the information is
needed.

This patch adds the following new interfaces for I/O xAPIC
hotplug. The implementation of these interfaces depends on each
architecture.
o int acpi_register_ioapic(acpi_handle handle, u64 phys_addr,
u32 gsi_base);
This new interface is to add a new I/O xAPIC specified by
phys_addr and gsi_base pair. phys_addr is the physical address
to which the I/O xAPIC is mapped and gsi_base is global system
interrupt base of the I/O xAPIC. acpi_register_ioapic returns
0 on success, or negative value on error.
o int acpi_unregister_ioapic(acpi_handle handle, u32 gsi_base);
This new interface is to remove a I/O xAPIC specified by
gsi_base. acpi_unregister_ioapic returns 0 on success, or
negative value on error.

x86_64 genapic mechanism should be aware of machines that use physical APIC
mode regardless of how many clusters/processors are detected.
ACPI 3.0 FADT makes this determination very simple by providing a feature
flag "force_apic_physical_destination_mode" to state whether the machine
unconditionally uses physical APIC mode.
Unisys' next generation x86_64 ES7000 will need to utilize this FADT
feature flag in order to boot the x86_64 kernel in the correct APIC mode.
This patch has been tested on both x86_64 commodity and ES7000 boxes.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
