The low-level mlx4 driver modified the page-list addresses for fast
register work requests post send to big-endian, and set a "present"
bit. This caused problems later when the consumer attempted to unmap
the pages using the page-list (using the list addresses which were
assumed to be still in CPU-endian order). Fix the mlx4 driver to
allocate two buffers and use a private buffer for the hardware-format
bus addresses.
This patch fixes <https://bugs.openfabrics.org/show_bug.cgi?id=1571>,
an NFS/RDMA server crash. The cause of the crash was found by Vu Pham
of Mellanox. The fix is along the lines suggested by Steve Wise in
comment #21 in bug 1571.

When the SQ is flushed, mark the flushed entries as not signaled so
the poll logic doesn't re-insert the CQ entry thinking its an out of
order completion.
The bug can cause the NFS/RDMA server to crash due to processing the
same completed work request twice.

hd dance around local irq and HD_IRQ enable without achieving much.
It ends up transferring data from irq handler with both local irq and
HD_IRQ disabled. The only place it actually does something is while
transferring the first block of a request which it does with HD_IRQ
disabled but local irq enabled.
Unfortunately, the dancing is horribly broken from locking POV. IRQ
and timeout handlers access block queue without grabbing the queue
lock and running the driver in SMP configuration crashes the whole
machine pretty quickly.
Remove meaningless irq enable/disable dancing and add proper locking
in issue, irq and timeout paths.

Default voltage constraints were being provided for fixed voltage
regulator where board constraints were not provided but these constraints
used INT_MIN as the default minimum voltage which is not a valid value
since it is less than zero. Use 1uV instead.
Also set the default values we set in the constraints themselves since
otherwise the max_uV constraint we determine will not be stored in the
actual constraint strucutre and will therefore not be used.

During regulator registration, any error after device_register() will
cause a double-free on the struct regulator_dev 'rdev'. The bug is in
drivers/regulator/core.c:regulator_register():
...
scrub:
device_unregister(&rdev->dev);
clean:
kfree(rdev); <---
rdev = ERR_PTR(ret);
goto out;
...
device_unregister() calls regulator_dev_release() which frees rdev. The
subsequent kfree corrupts memory and causes some OMAP3 systems to oops on
boot in regulator_get().
Applies against 2.6.30-rc3.

Running large cluster setup, we are hanging after many hours of
testing. Fixing this required going over the code and making sure the
rexmit entry was properly removed based on the cm_node's state and
packet received. Also when receiving a FIN packet, check seq# and
make sure there were no errors before calling handle_fin().
Following are the changes done in nes_cm.c:
* handle_ack_pkt() needs to return error value, so in case of error,
handle_fin() is not called. Some cleanup done while going over the code.
* handle_rst_pkt(), handling of cm_node's NES_CM_STATE_LAST_ACK is missing.
* process_packet(), in case of FIN only packet is received, call
check_seq() before processing.
* in handle_fin_pkt(), we are calling cleanup_retrans_entry() for all
conditions, even if the packets need to be dropped.

The umem driver issues two warnings on boot, due to blk_plug_device() and
blk_remove_plug() being called without q->queue_lock held. Starting with
e48ec690 (block: extend queue_flag bitops), the queue_flag_* functions
warn if q->queue_lock doesn't appear to be locked. In fact, q->queue_lock
is NULL (though that apparently isn't otherwise a problem as the driver is
using card->lock for everything).
Although blk_init_queue() with take a request_fn_proc and spinlock_t*,
there isn't a corresponding init helper that takes a make_request_fn.
Setting queue_lock to &card->lock explicitly seems to work fine for me.
The warning goes away and the device appears to behave.
