Newer HCAs have a HW option to write a sequence number to each receive
queue entry and avoid a separate DMA of the tail register to memory.
This patch adds support for these changes.

In slave_or_pri_blk(), pci_write_config_byte() is used to write a
16-bit quantity to clear linkctrl CRC error bits. This is clearly a
bug and also causes the warning
drivers/infiniband/hw/ipath/ipath_iba6110.c: In function 'slave_or_pri_blk':
drivers/infiniband/hw/ipath/ipath_iba6110.c:849: warning: overflow in implicit constant conversion
Fix this by using pci_write_config_word() instead.

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.

The original QHT7040 had significant performance issues so there was an
additional check in the driver for a newer serial number. Support for
the small quantities of that board shipped has been dropped, so this
patch removes the special checks to simplify the code.

The 6110 had a bug that caused some registers to be swapped; it was
fixed for the 7220 (and didn't affect the 6120 because it had fewer
registers). This adds a flag and related code to handle that, and
includes some minor cleanups in the same area.

Various hardware counters are exported via the ipath file system (since
it is binary data). The old file format was very dependent on the HW
offsets for these registers. Newer HCA chips can have different
counters at different offsets. This patch adds a level of indirection
to make the file format consistent across HCAs.

A couple of chip bugs in the iba6110 and in the iba6120 are not in more
recent chips. This first bug swaps two of the pioavail register
locations. In the second bug, the chip can sometimes forget to dma the
pio avail register to memory. We indicate the presence of these bugs
with runtime flags and we indicate the presence of the flags by bumping
the SWMINOR.

On iba6110 rev4, support for three more IB counters were added. The
LocalLinkIntegrityError counter, the ExcessiveBufferOverrunErrors
counter and support for error counting of flow control packets on an
invalid VL. These counters trigger GPIO interrupts and the sw keeps
track of the counts. Since we also use GPIO interrupts to signal packet
reception, we need to turn off the fast interrupts, or we risk losing a
GPIO interrupt.

We are more careful to be sure that we don't lose information about
changes that occurred while we were in freeze mode, when the chip will
not notify us, and try to avoid false error interrupts while doing
cleanup. Put all of this logic in a new function ipath_clear_freeze().

This centralizes the use of the abort functionality, removes the
unneeded buffer cancel (abort does the same thing), sets up to ignore
launch errors after abort, same as cancel. We need abort on exit from
freeze mode to avoid having buffers stuck in the busy state, if a user
process happened to complete the send while we were in freeze mode
doing the recovery.

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.

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.

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.

We can sometimes trigger parity errors due to processor speculative
reads to our write-combined memory (mostly seen on Woodcrest). Add a
stats counter for these.
Factored out the sendbuffererror buffer cancellation code so it can be

within two jiffies of the cancellation.
Also restore 2 dropped TXE lines on hwe_bitsextant noticed while
