HP is recycling both DMI_PRODUCT_NAME and DMI_BIOS_VERSION making
ahci_broken_suspend() trigger for later products which are not
affected by the original problems.  Match BIOS date instead of version
and add references to bko's so that full information can be found
easier later.

bko#15481 shows that we're missing some NVIDIA ahci PCI IDs.  Peer
Chen confirms that IDs 0x580-0x58f are reserved for cases where Linux
ID option is selected in the BIOS and are only used for mcp65-73.  Add
0x0581-0x058f.

There's no real need for a pointer to the MADT to be global. The only
function who uses it is map_madt_entry.

Now that the early _PDC evaluation path knows how to correctly
evaluate _PDC on only physically present processors, there's no
need for the processor driver to evaluate it later when it loads.

To cover the hotplug case, push _PDC evaluation down into the
hotplug paths.

Detect if a processor is physically present before evaluating _PDC.

We want this because some BIOS will provide a _PDC even for processors
that are not present. These bogus _PDC methods then attempt to load
non-existent tables, which causes problems.

We've renamed the old processor_core.c to processor_driver.c, to
convey the idea that it can be built modular and has driver-like
bits.

Now let's re-create a processor_core.c for the bits needed
statically by the rest of the kernel. The contents of processor_pdc.c
are a good starting spot, so let's just rename that file and
complete our three card monte.

The ACPI processor driver can be built as a module. But it has
pieces of code that should always be built statically into the
kernel.

The plan is for processor_core.c to contain the static bits while
processor_driver.c contains the module-like bits.

Since the bulk of the code in the current processor_core.c is
module-like, first step is to rename the file to processor_driver.c

Next step will re-create processor_core.c and cherry-pick out
the static bits.

I pulled them into Linux-2.6 on 2003-08-09.
Over the last 6+ years, several entries have proven to be
unnecessary and deleted, while no new entries have been added.
Matthew suggests that they now have negative value, and I agree.
