Okay, here it is, slightly expanded version. It actually makes use of
newly defined type for type-checking purposes; still no code changes.

 BARs of host bridges often have special meaning and AFAIK are best left
to be setup by the firmware or system-specific startup code and kept
intact by the generic resource handler.  For example a couple of host
bridges used for MIPS processors interpret BARs as target-mode decoders
for accessing host memory by PCI masters (which is quite reasonable).
For them it's desirable to keep their decoded address range overlapping
with the host RAM for simplicity if nothing else (I can imagine running
out of address space with lots of memory and 32-bit PCI with no DAC
support in the participating devices).

 This is already the case with the i386 and ppc platform-specific PCI
resource allocators.  Please consider the following change for the generic
allocator.  Currently we have a pile of hacks implemented for host bridges
to be left untouched and I'd be pleased to remove them.

The patch below lets five files under drivers/pci/hotplug/ simply use
MODULE to check whether they are compiled as part of a module.

MODULE is the common idiom for checking whether a file is built as part
of a module.

closely, the previous #if's in cpcihp_generic.c and cpci_hotplug_pci.c

The documentation says dma_set_api() returns 1 on success and
0 on error, which is plain wrong, standard kernel return codes
are used instead (0 on ok, -ESOMETHING on error).

The meye hardware needs to access the main memory for DMA using
32 bit addresses. The previous version of the meye driver used
dma_addr_t types to build those addresses and ensured that
sizeof(dma_addr_t) = 4 by disabling HIGHMEM64G in Kconfig.

However, this way of doing it also makes meye unavailable on
some kernel configurations. As Arjan said previously, future Fedora
kernels may have HIGHMEM64G activated by default (davej says it won't
happen, at least for now...). Other distributions may do the same and
this will require meye users to recompile the whole kernel.

The attached patch makes the meye driver use dma_addr_t addresses 
internally, but converts them to u32 before giving them to the
hardware.

When adding or deleting from the source list make sure to find matches
by comparing against the new source address, not the group address.
Also, check each addr in the list rather than just the first one.
And, finally, only delete from list when there's a match rather than
vice-versa.  Drop the effort to keep list sorted, since it's not done
on full-state api and can create an sl_addr entry that the delta api
won't be able to delete. Without these fixes sl_count can be corrupted
which can allow for kernel memory corruption.

I recently learnt that limiting RAM with by using only "mem=xxxM" is no
good on machines equipped with PCI.  In my case (vanilla 2.6.9) the cardbus
bridge on my laptop got mapped to the unused RAM area which resulted in
wierd errors due to the collision.

The right solution is to use "mem=" together with "memmap=" to mark the
unused RAM area reserved.

Henceforth I force the kernel to use 2016MiB by passing "mem=2016M
memmap=32M#2016M" instead of just "mem=2016M".
