Now that IRQ allocation is done in myri10ge_open(), we want to still

Additionaly, we fix the initialization and printing of netdev->irq.

Similar to this commit:
http://kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=d15e9c4d9a75702b30e00cdf95c71c88e3f3f51e
It's not safe in cp_start_xmit to blindly call spin_lock_irq and then
spin_unlock_irq, since it may very well be the case that cp_start_xmit
was called with interrupts already disabled (I came across this bug in
the context of netdump in RedHat kernels, but the same issue holds, for
example, in netconsole). Therefore, replace all instances of
spin_lock_irq and spin_unlock_irq with spin_lock_irqsave and
spin_unlock_irqrestore, respectively, in cp_start_xmit(). I tested this
against a fully-virtualized Xen guest using netdump, which happens to
use the 8139cp driver to talk to the emulated hardware. I don't have a
real piece of 8139cp hardware to test on, so someone else will have to
do that.

The introduction of Jens Axboe's explicit i/o plugging patches introduced a
deadlock in jfs. This was caused by the process initiating I/O not
unplugging the queue before waiting on the commit thread. The commit
thread itself was waiting for that I/O to complete. Calling io_schedule()
rather than schedule() unplugs the I/O queue avoiding the deadlock, and it
appears to be the right function to call in any case.

vivi.c uses the KM_BOUNCE_READ with local interrupts enabled.
This means that if a disk interrupt occurs while vivi.c is using this
fixmap slot, the vivi.c driver will, upon return from that interrupt, find
that the fixmap slot now points at a different physical page.
The net result will probably be rare corruption of disk file contents,
because viv.c will now be altering the page which the disk code was
recently using.

Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
sas_task_abort() should simply abort the upper-level SCSI command and wait
until the error handler to send the actual ABORT TASK command. By
deferring things to the EH we simplify the concurrency coordination and
eliminate some race conditions. Note that sas_task_abort has a few hooks
to handle libsas internal commands properly too.
Also rename do_sas_task_abort to __sas_task_abort just in case we really
want to abort the task *right now* and we don't have a scsi_cmnd attached
to the command. This is a hook for libata internal commands to abort.

When a SAS LLDD needs to request a device port reset, it needs to have all
commands aborted before it can reset the port. Since commands are put on

port after all commands are aborted.
