Handle more bogus MCFG entries
Some Asus P4 boards seem to have broken MCFG tables with
only a single entry for busses 0-0. Special case these
and assume they mean all busses can be accessed.

Error checking is scattered through various layers of the dlpar code,
leading to a somewhat opaque code structure. This patch consolidates
error checking in one routine, simplifying the code a tad. There's
also some whitespace cleanup here too.

Minor cleanup. Move structure initializer to bottom of file,

Minor cleanup. Add the prefix rpaphp_* to several generic-sounding routines.
Remove rpaphp_remove_slot(), which is a one-liner.

Remove general baroqueness. The function rpaphp_enable_pci_slot()
has a fairly simple logic structure, once all of the debug printk's
are removed. Its called from only one place, and that place also
has a very simple structure once he printk's are removed. Merge
the two together.

Remove general baroqueness. The function rpaphp_unconfig_pci_adapter()
is really just three lines of code, once all the dbg printks are removed.
And its called in only one place. So replace the call by the thre lines.
Also, provide proper semaphore locking in the affected function
disable_slot()

This patch fixes the AMD POGO errata on the hotplug controller where the
platform will lock up or reboot if PERR/SERR generation is enabled and a
slot is sent an enable command. This fix disables PERR/SERR generation
before a slot is sent the enable command by first saving related
registers, turning off SERR/PERR generation, enabling the slot, then
restoring the registers.

Removing and then adding a PCI slot to a running partition results in
a kernel panic. The current code attempts to add iospace for an entire
root bus, which is inappropriate, and silently fails. When a pci device
tries to use the iospace, a page fault is taken, as the iospace had not
been mapped, and of course the page fault cannot be resolved.
This only occurs for PCI adapters using pio, which may be why it hadn't
been seen earlier (this seems to have been broken for a while).
This patch has survived testing of dozens of slot add and removes.

The RPAPHP hoplug driver will not build as a module, because it calls
on pci_claim_resource(), which is not exported. This exports the symbol.
Problem reported by Olaf Hering <olh@suse.de>
A grep indicates that building drivers/parisc/lba_pci.c
would have trouble building as a module for the same reason.

Somewhere between 2.6.14 and 2.6.15-rc3, some PCI ids were apparently
removed. The ecc.c module, which is not a part of the kernel.org tree, but
included in some distributions, fails to compile.

I missed this usage in drivers/pci/msi.h:
#ifdef CONFIG_SMP
#define set_msi_irq_affinity set_msi_affinity
#else
#define set_msi_irq_affinity NULL
#endif
set_msi_affinity() is declared and exclusively used in msi.c.
Here's a better way so (hopefully) history doesn't repeat itself.
