We have observed unstable link with a new BNT switch.
Add wide_ppm_offset parameter to allow the user to control the clock
ppm offset on the CX4 interface for better compatibility. Default is
100ppm, setting it to 1 will increase it to 300ppm. Change default
SerDes1 reference clock to external source.

SFP+ PHY initialization has very long delays, incorrect settings for
direct attach copper cables, and inconsistent link detection.
Adjust delays to the minimum required by the PHY. Worst case is now
less than 4 seconds. Add new register settings for direct attach
cables. Change link detection logic to use two new registers for more
consistent link state detection. Reorganize code to shorten line
length.

We are getting crash or hung situation when we are running network
cable pull tests during RDMA traffic.
In schedule_nes_timer(), we return an error if nes_nic_cm_xmit()
returns failure. This is changed to success as skb is being put on
the timer routines to be processed later. In send_syn() case, we are
indicating connect failure once from nes_connect() and the other when
the rexmit retries expires.
The other issue is skb->users which we are incrementing before calling
nes_nic_cm_xmit() which calls dev_queue_xmit() but in case of failure
we are decrementing the skb->users at the same time putting the skb on
the rexmit path. Even if dev_queue_xmit() fails, the skb->users is
decremented already. We are removing the decrement of skb->users in
case of failure from both schedule_nes_timer() as well as from
nes_cm_timer_tick().
There is also extra check in nes_cm_timer_tick() for rexmit failure
which does a break from the loop is removed. This causes problem as
the other nodes have their cm_node->ref_count incremented and are not
processed.

Fix issues found by static code analysis:
(1) Check if cm_node was successfully created for loopback connection.
(2) schedule_nes_timer() does not free up allocated memory after
encountering an error. There is a WARN_ON() for this condition.
(3) there is a cm_node->freed flag which is set but not used.

The were some incorrect casts to unsigned long that caused 64-bit values
to be truncated on 32-bit architectures and made the driver pass invalid
adresses and lengths to the hardware. The problems were primarily seen
with kernels with highmem configured but some could show up in
non-highmem kernels, too.

When doing rdma_resolve_addr(), if the relevant IB port is down, the
function fails and the cm_id is not bound to the correct device.
Therefore, application does not have a device handle and cannot wait
for the port to become active. The function fails because the
underlying IPoIB interface is not joined to the broadcast group and
therefore the SA does not have a multicast record to take a Q_Key
from.
The fix is to use lazy Q_Key resolution - cma_set_qkey() will set
id_priv->qkey if it was not set, and will be called just before the
Q_Key is really required.

Some cards are not able to calculate a valid CRC16 value
for CID and CSD reads (CRC for 512 byte data blocks is OK).
By moving the CRC enable after the read of CID and CSD, these
cards can be used. This patch was tested with a faulty 8 GByte
takeMS Class 6 SDHC card. This patch was suggested by
Pierre Ossman.

Spurious IRQs seen on MMC after 2.6.29. Flush posted write in IRQ
handler.
The interrupt line is released by clearing the error status bits
in the MMCHS_STAT register, which must occur before the interrupt
handler returns to avoid unwanted irqs. Hence the need to flush
the posted write.

Commit 4aaf2fec718f6fbf38668edf733a0ab09a49cab1 (xsysace: make it
'struct hd_driveid'-free) converted the cf_id member of 'struct
ace_device' from a 'struct hd_driveid' to a u16 array. However,
references to the base of the structure were still using the '&'
operator. When the address was used with the ata_id_u32() macro, the
compiler used the size of the entire array instead of sizeof(u16) to
calculate the offset from the base address.
This patch removes the use of the '&' operator from all references of
cf_id to fix the bug and remove future confusion.

Simplify tf_read() method, making it deal only with 'struct ide_taskfile' and
the validity flags that the upper layer passes, and factoring out the code that
deals with the high order bytes into ide_tf_readback() to be called from the
only two functions interested, ide_complete_cmd() and ide_dump_sector().
This should stop the needless code duplication in this method and so make
it about twice smaller than it was; along with simplifying the setup for
the method call, this should save both time and space...

This happens because falconide relies on {in,out}sw() being redefined in
<asm/ide.h>, as included by <linux/ide.h>, which is no longer the case.
Use __ide_mm_{in,out}sw() from <asm/ide.h> instead, just like

commit 255115fb35f80735c21a1cbe9809e9795a3af26e ("ide: allow host drivers to
specify IRQ flags") added irq_flags fields to struct ide_port_info and struct
ide_host. Drivers can now set ide_port_info.irq_flags = IRQF_SHARED, while
init_irq() passes ide_host.irq_flags to request_irq().
Unfortunately ide_host.irq_flags is never set, causing (on ARAnyM):
| Uniform Multi-Platform E-IDE driver
| ide: Falcon IDE controller
| Probing IDE interface ide0...
| hda: Sarge m68k, ATA DISK drive
| init_irq: sa = 0
| ide0: disabled, unable to get IRQ 15
| ide0: failed to initialize IDE interface
| ide0: disabling port
Solve this by copying ide_port_info.irq_flags to ide_host.irq_flags in
ide_host_alloc().
This bug probably affects the following IDE host drivers:
- buddha
- delkin_cb
- falconide
- gayle
- ide-cs
- macide
- q40ide
- scc_pata
- sgiioc4
