Let attribute group vectors be declared "const". We'd
like to let most attribute metadata live in read-only

Modern I/O buses like PCIe and HT can be configured for multiple speeds
and widths. When an ipath HCA seems to have lower than expected
performance, it is very useful to be able to display what the driver
thinks the bus speed is.

IBA7220 includes many more configurable IB settings. Getting/setting
these is now grouped into a pair of chip specific functions accessed via
function pointers. Provide sysfs access to these settings.

Commit 23b9c1ab ("Infiniband: make ipath driver use default driver
groups.") introduced a bug in the ipath driver where
ipath_device_create_group() fell through into the error path, even on
success, which meant that the sysfs groups it created would always get
removed right away. This made ipath_device_remove_group() hit the
BUG_ON() in sysfs_remove_group() when it tried to remove those groups a
second time.
Correct the return path so that the groups stick around until they are
supposed to be cleaned up.

Make the ipath driver use the new driver functions so that it does not
touch the sysfs portion of the driver structure.
We also remove the redundant symlink from the device back to the driver,
as it is already in the sysfs tree. Any userspace tools should be using
the standard symlink, not some driver specific one.

This patch adds the ability to set the LMC via a sysfs file as if the SM
sent a SubnSet(PortInfo) MAD. It is useful for debugging when no SM is
running.

We currently track various errors, now we enhance that capability by
logging some of them to EEPROM. We also now log a cumulative "active"
time defined by traffic though the InfiniPath HCA beyond the normal SM
traffic.

When we want to find an InfiniPath HCA in a rack of nodes, it is often
expeditious to blink the status LEDs via a userspace /sys file.
A write-only led_override "file" is published per device. Writes to
this file are interpreted as (string form) numbers, and the resulting
value sent to ipath_set_led_override(). The upper eight bits are
interpretted as a 4.4 fixed-point "frequency in Hertz", and the bottom
two 4-bit values are alternately (D0..3, then D4..7) used by the
board-specific LED-setting function to override the normal state.

I noticed that many source files include <linux/pci.h> while they do
not appear to need it. Here is an attempt to clean it all up.
In order to find all possibly affected files, I searched for all
files including <linux/pci.h> but without any other occurence of "pci"
or "PCI". I removed the include statement from all of these, then I
compiled an allmodconfig kernel on both i386 and x86_64 and fixed the
false positives manually.
My tests covered 66% of the affected files, so there could be false
positives remaining. Untested files are:

I would welcome test reports for these files. I am fine with removing
the untested files from the patch if the general opinion is that these
changes aren't safe. The tested part would still be nice to have.
Note that this patch depends on another header fixup patch I submitted
to LKML yesterday:

inline the simple stuff that the layer code was doing.

Remove ips namespace from infinipath drivers. This renames ips_common.h to
ipath_common.h. Definitions, data structures, etc. that were not used by
kernel modules have moved to user-only headers. All names including ips have
been renamed to ipath. Some names have had an ipath prefix added.

The ipathfs filesystem contains files that are not appropriate for
sysfs, because they contain binary data. The hierarchy is simple; the
top-level directory contains driver-wide attribute files, while numbered
subdirectories contain per-device attribute files.
Our userspace code currently expects this filesystem to be mounted on
/ipathfs, but a final location has not yet been chosen.
