Fixed up conflict in arch/powerpc/kernel/pci_64.c due to OF device tree
scanning having been moved and merged for the 32- and 64-bit cases. The
'needs_freset' initialization added in 6e19314cc ("PCI/powerpc: support
PCIe fundamental reset") is now in arch/powerpc/kernel/pci_of_scan.c.
The current mp_bus_to_node array is initialized only by AMD specific
code, since AMD platforms have registers that can be used for
determining mode numbers. On new Intel platforms it's necessary to
initialize this array as well though, otherwise all PCI node numbers
will be 0, when in fact they should be -1 (indicating that I/O isn't
tied to any particular node).
So move the mp_bus_to_node code into the common PCI code, and
initialize it early with a default value of -1. This may be overridden
later by arch code (e.g. the AMD code).
With this change, PCI consistent memory and other node specific
allocations (e.g. skbuff allocs) should occur on the "current" node.
If, for performance reasons, applications want to be bound to specific
nodes, they should open their devices only after being pinned to the
CPU where they'll run, for maximum locality.

There are cases where full date information is required instead of
just the year. Add month and day parsing to dmi_get_year() and rename
it to dmi_get_date().
As the original function only required '/' followed by any number of
parseable characters at the end of the string, keep that behavior to
avoid upsetting existing users.
The new function takes dates of format [mm[/dd]]/yy[yy]. Year, month
and date are checked to be in the ranges of [1-9999], [1-12] and
[1-31] respectively and any invalid or out-of-range component is
returned as zero.
The dummy implementation is updated accordingly but the return value
is updated to indicate field not found which is consistent with how
other dummy functions behave.

commit 30a18d6c3f
Date: Tue Feb 19 03:21:20 2008 -0800
x86: multi pci root bus with different io resource range, on
64-bit
It turns out that:
1. that AMD-based systems have two HT chains.
2. BIOS doesn't allocate resources for BAR 6 of devices under 8132 etc
3. that multi-peer-root patch will try to split root resources to peer
root resources according to PCI conf of NB
4. PCI core assigns unassigned resources, but they overlap with BARs
that are used by ioapic addr of io4 and 8132.
The reason: at that point ioapic address are not inserted yet. Solution
is to insert ioapic resources into the tree a bit earlier.

Issue a warning if _CRS returns too many resource descriptors to be
accommodated by the fixed size resource array instances. If there is no
transparent bridge on the root bus "too many" is the
PCI_BUS_NUM_RESOURCES size of the resource array. Otherwise, the last 3
slots of the resource array must be excluded making the maximum
(PCI_BUS_NUM_RESOURCES - 3).
The current code:
- is silent when _CRS returns too many resource descriptors and

So we can set io apic routing only when enabling the device irq.
This is advantageous for IRQ descriptor allocation affinity: if we set up
the IO-APIC entry later, we have a chance to allocate the IRQ descriptor
later and know which device it is on and can set affinity accordingly.

pci mmap code was doing memtype reserve for a while now. Recently we
added memtype tracking in remap_pfn_range, and pci code indirectly calls
remap_pfn_range. So, we don't need seperate tracking in pci code
anymore. Which means a patch that removes ~50 lines of code :-).
Also, recently we found out that the pci tracking is not working as we expect
it to work in some cases. Specifically, userlevel X mmap of pci, with some
recent version of X, is having a problem with vm_page_prot getting reset.
The pci tracking uses vm_page_prot to pass on the protection type from parent
to child during fork.
a) Parent does a pci mmap
b) We look at PAT and get either UC_MINUS or WC mapping for parent
c) Store that mapping type in vma vm_page_prot for future use
d) This thread does a fork
e) Fork results in mmap_ops ->open for the child process
f) We get the vm_page_prot from vma and reserve that type for the child process
But, between c) and e) above, the vma vm_page_prot is getting reset to zero.
This results in PAT reserve failing at the time of fork as in here.
http://marc.info/?l=linux-kernel&m=123858163103240&w=2
This cleanup makes the above problem go away as we do not depend on
vm_page_prot in our PAT code anymore.

While looking at the issue in the thread:
http://marc.info/?l=dri-devel&m=123606627824556&w=2
noticed a bug in pci PAT code and memory type setting.
PCI mmap code did not set the proper protection in vma, when it
inherited protection in reserve_memtype. This bug only affects
the case where there exists a WC mapping before X does an mmap
with /proc or /sys pci interface. This will cause X userlevel
mmap from /proc or /sysfs to fail on fork.
