e8e7ad7115 IB/ipath: Add capability to modify PBC word
During compliance testing and when debugging some interconnect issues,
it is very useful to be able to send malformed packets, without having
the device signal them as malformed (drop, or terminate with EBP). The
hardware supports this, but the driver "diagnostic packet" interface
did not.

Extend capability to send specific malformed packets for testing.

bacf401353 IB/ipath: Make handling of one subport consistent
Previously the driver and userspace code handled the case of 1 subport
somewhat inconsistently.  The new interpretation of this situation is
that if one subport is requested, the driver turns on the subport
mechanism and arranges for the port to be "shared" by one process.  In
normal use the userspace library does not use this configuration and
instead arranges for the port not to be shared at all.  This
particular idiom can be useful for testing purposes.

0df6291c8a IB/ipath: Correct checking of swminor version field when using subports
When subports are required to run a program, this patch checks that
the driver and the userspace library have compatible subport
implementations.  This is achieved through checks on the swminor
version field built into the driver and userspace library.  Bad
combinations are reported through syslog and result in an error when
opening the port.

d781b129f1 IB/ipath: Duplicate RDMA reads can cause responder to NAK inappropriately
A duplicate RDMA read request can fool the responder into NAKing a new
RDMA read request because the responder wasn't keeping track of
whether the queue of RDMA read requests had been sent at least once.
For example, requester sends 4 2K byte RDMA read requests, times out,
and resends the first, then sees the 4 responses, then sends a 5th
RDMA read or atomic operation.  The responder sees the 4 requests,
sends 4 responses, sees the resent 1st request, rewinds the queue,
then sees the 5th request but thinks the queue is full and that the
requester is invalidly sending a 5th new request.

30d149ab58 IB/ipath: Fix possible data corruption if multiple SGEs used for receive
The code to copy data from the receive queue buffers to the IB SGEs
doesn't check the SGE length, only the memory region/page length when
copying data.  This could overwrite parts of the user's memory that
were not intended to be written.  It can only happen if multiple SGEs
are used to describe a receive buffer which almost never happens in
practice.

f716cdfe57 IB/ipath: Change use of constants for TID type to defined values
Define pkt rcvd 'type' in a way consistent with HW spec and chips.

The hardware considers received packets of type 0 to be expected, and
type 1 to be eager. The driver was calling the ipath_f_put_tid
functions using a variable called 'type' set to 0 for eager and to 1
for expected packets.  Worse, the iba6110 and iba6120 drivers used
those values inconsistently.  This was quite confusing.  Now
everything is consistent with the hardware.

17b2eb9fe6 IB/ipath: Lock and always use shadow copies of GPIO register
The new LED blinking interface adds more contention for the
unprotected GPIO pins that were already shared, though not commonly at
the same time.  We add locks to the accesses to these pins so that
Read-Modify-Write is now safe.  Some of these locks are added at
interrupt context, so we shadow the registers which drive and inspect
these pins to avoid the mmio read/writes.  This mitigates the effects
of the locks and hastens us through the interrupt.

Add locking and always use shadows for registers controlling GPIO pins
(ExtCtrl and GPIOout). The use of shadows implies doing less I/O,
which can make I2C operation too fast on some platforms. An explicit
udelay(1) in SCL manipulation fixes that.

82466f00ec IB/ipath: Support blinking LEDs with an led_override file
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.

f139749001 firewire: support S100B...S400B and link slower than PHY
Use a speed probe to determine the speed over 1394b buses and of nodes
which report a link speed less than their PHY speed.

Log the effective maximum speed of newly created nodes in dmesg.

Also, read the config ROM (except bus info block) at the maximum speed
rather than S100.  This isn't a real optimization though because we
still only use quadlet read requests for the entire ROM.

The patch also adds support for S1600 and S3200, although such hardware
does not exist yet.

24d40125f1 firewire: optimize gap count with 1394b leaf nodes
Table-based gap count optimization cannot be used if 1394b repeater PHYs
are present.  But it does work with 1394b leaf nodes.
