Avoid unaligned accesses to extended capabilities.
The PCIe spec tells that all capabilities must be DWORD aligned and the bottom
2 bits of all capability pointers are reserved for future use and must be
ignored when read.

Improve large BAR display
lspci currently displays anything larger than 2GB as a raw number.
I have a device with a larger BAR and wanted to see that reported as
a multiple of a GB.
I took the opportunity to rewrite this routine to make it easier to add
higher powers in the future. It's also slightly shorter, which is nice.
I also changed it to use the binary prefixes, much as I dislike them
personally.

Make Physical Slot work for multifunction cards
I have some multifunction cards in a machine which supports physical
slots. Currently, lspci only displays the Physical Slot for the last
function in the slot. I believe it should display it for all of them.

lspci: Show SR-IOV VF BARs

file timestamp not needed in pci.ids.gz
File timestamp (and file name) have no use for pci.ids.gz
This allow to produce the exact same file even when compiled at different times.
That make paranoid happy.
Even gzip-1.2.4 from 1993 support -n option
Concerning the fact that -n did not include file name, that does not matter
unless the compressed file is moved under a different name and later -N option
is used to open the file.

Stop early if the VPD is corrupt
I have several cards which report more-or-less garbage in their VPD.
It can take an extraordinarily long time to read all their VPD and none
of it is of interest. Instead, if we find an unknown resource type,
just stop trying to read any more.

Improve MSI and MSI-X display
There are several ways I think the MSI and MSI-X capabilities could be
reported better in lspci.
Enable is at the beginning of the MSI-X report, but the end of the
MSI report. Because Enabled is perhaps the most important thing,
I moved it to the start.
The TabSize reported for MSI-X is perhaps a little obscure. I feel
'Count' works better (and is then the same as MSI). We can't readily
tell which of the MSI-X capabilities have been programmed, so we can't
report how many have been enabled.
Both capabilities report 'Mask'. Unfortunately, in MSI, it indicates
whether the device supports per-vector masking, and in MSI-X it indicates
whether all the vectors are masked. This patch changes both; MSI reports
'Maskable' and MSI-X reports 'Masked'.
All these changes combine to turn the report from this:

proc: Work around broken /proc/bus/pci/ on some architectures.
Several architectures (e.g., sparc64) use domains in proc directory
names, which is inconsistent, because /proc/bus/pci/devices is still
unable to represent domains.
Work around it, so that the proc back-end works at least on single-domain
machines.
Vendor- and system-specific VPD items are matched only by their first
character, so we cannot read the item id from the matching structure.
There is a similar issue with unknown VPD items, which is handled by
creating a matching structure dynamically.
We can handle both cases using the static matching structure and the
actual item id, so do that.

Fix inconsistent bus centric view between the sysfs and proc methods
The vendor and device IDs may be different when using sysfs and proc
methods with bus centric view enabled. The sysfs method reads the IDs
from the configuration space rather than uses the values from sysfs
entries. But the proc method always uses values from the proc files.
This fix makes the proc method use the values from the configuration
space too for bus centric view.

Display physical slot information in lspci -v
We've been exposing slot information in /sys/bus/pci/slots for a
long time now (as long as a hotplug driver or slot detection
driver like pci_slot is loaded).
Let's make life better for our users and display that information
in lspci. If slot entries appear in /sys/bus/pci/slots/,
correlate them to PCI devices, and display the information when
lspci -v is issued.
If no slot entries appear in sysfs (due to no modules loaded), do
nothing.
Now you'll see sample output like the following:
