Matthew Wilcox 0bb1be3e30 x86/PCI: Move set_pci_bus_resources_arch_default into arch/x86
Commit 30a18d6c3f introduced a new
function to set the PCI bus resources.  Unfortunately, neither the
author, nor the committers seemed to know that we already have somewhere
to do that -- pcibios_fixup_bus().  This patch moves the hook (used only
by the K8 code) into x86-specific code where it should have been in the
first place.

Suresh Siddha 5a3ae27605 x86, PAT: Remove duplicate memtype reserve in pci mmap
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.

Pallipadi, Venkatesh 9cdec04938 x86, PAT, PCI: Change vma prot in pci_mmap to reflect inherited prot
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.

Yinghai Lu 068258bc15 x86/PCI: host mmconfig detect clean up
Fix mmconfig detection to not assume a single mmconfig space in the
northbridge, paving the way for AMD fam10h + mcp55 CPUs.  On those, the
MSR has some range, but the mcp55 pci config will have another one.

Also helps the mcp55 + io55 case, where every one will have one range.

If it is mcp55, exclude the range that is used by CPU MSR, in other
words , if the CPU claims busses 0-255, the range in mcp55 is dropped,
because CPU HW will not route those ranges to mcp55 mmconfig to handle
it.

Yinghai Lu dfadd9edff PCI/x86: detect host bridge config space size w/o using quirks
Many host bridges support a 4k config space, so check them directy
instead of using quirks to add them.

We only need to do this extra check for host bridges at this point,
because only host bridges are known to have extended address space
without also having a PCI-X/PCI-E caps.  Other devices with this
property could be done with quirks (if there are any).

As a bonus, we can remove the quirks for AMD host bridges with family
10h and 11h since they're not needed any more.

With this patch, we can get correct pci cfg size of new Intel CPUs/IOHs
with host bridges.

Bjorn Helgaas 600914ba52 PCI/x86: make early dump handle multi-function devices
The early "dump PCI config space" code skips many multi-function
devices.  This patch fixes that, so it dumps all devices in PCI
domain 0.

We should not skip the rest of the functions if CLASS_REVISION is
0xffffffff.  Often multi-function devices have gaps in the function ID
space, e.g., 1c.0 and 1c.2 exist but 1c.1 doesn't.  The CLASS_REVISION
of the non-existent 1c.1 function will appear to be 0xffffffff.

We should only look at the HEADER_TYPE of function zero.  Often the
"multi-function" is set in function zero, but not in other functions.

Impact: Changes reboot behavior.

If port CF9 seems to be safe to touch, attempt it before trying the
keyboard controller.  Port CF9 is not available on all chipsets (a
significant but decreasing number of modern chipsets don't implement
it), but port CF9 itself should in general be safe to poke (no ill
effects if unimplemented) on any system which has PCI Configuration
Method #1 or #2, as it falls inside the PCI configuration port range
in both cases.  No chipset without PCI is known to have port CF9,
either, although an explicit "pci=bios" would mean we miss this and
therefore don't use port CF9.  An explicit "reboot=pci" can be used to
force the use of port CF9.

Linus Torvalds 011fec7486 Un-break printk strings in x86 PCI probing code
Breaking lines due to some imaginary problem with a long line length is
often stupid and wrong, but never more so when it splits a string that
is printed out into multiple lines.  This really ended up making it much
harder to find where some error strings were printed out, because a
simple 'grep' didn't work.

I'm sure there is tons more of this particular idiocy hiding in other
places, but this particular case hit me once more last week. So fix it.
