The DASD device driver never reorders the I/O requests and relies on the
hardware to write all data to nonvolatile storage before signaling a
successful write. Hence, the only thing we have to do to support write
barriers is to set the queue ordered flag.

I noticed an occasional crash on wakeup from sleep on my powerbook
(strangly never happened before, probably timing related) that appears to
be due to a dangling interrupt while the chip is put to sleep and beeing
reset on wakeup.
This patch fixes is by disabling the irq in the ide pmac driver while
asleep and only re-enable it after the chip has been fully reset. This is
safe to do so as the interrupt of these apple IDE cells is never shared.

In order to properly fix some issues with cpufreq vs. sleep on

I must force a switch to full speed before sleep and I switch back to
previous speed on resume.
I also added a driver flag to disable the warnings in suspend/resume
since it is expected in this case to have different speed (and I want it

tg3_restart_ints() is called to re-enable interrupts after tg3_poll()
has finished all the work. It calls tg3_cond_int() to force an interrupt
if the status block updated bit is set. The updated bit will be set if
there is a new status block update sometime during tg3_poll() and it can
be very often. The worst part is that even if all the work has been
processed, the updated bit remains set and an interrupt will be forced
unnecessarily.
The fix is to call tg3_has_work() instead to determine if new work is
posted before forcing an interrupt. The way to force an interrupt is
also changed to use "coalesce_now" instead of "SETINT". The former is
generally a safer way to force the interrupt.
Also deleted the first parameter to tg3_has_work() which is unused.

This patch fixes a bug that causes tg3_has_work() to always return 1.
rx work is determined by comparing tp->rx_rcb_ptr with the current hw
producer index. The hw producer index is modulo the ring size, but tp-
>rx_rcb_ptr is a free running counter that goes up beyond the ring size.
After the ring wraps around once, tg3_has_work() will always return 1.
The fix is to always do modulo arithmetic on tp->rx_rcb_ptr.

This is a somewhat more comprehensive fix for the problem of devices
like the newer Zaurii ... or in this case some Motorola cell phones.
To recap, the problem's root cause is that these devices aren't using
standard USB class specifications for their network links, and so far
we've had to add lots of device-specific driver entries. The vendor
fix abuses the CDC MDLM descriptors (they _could_ have conformed to
the spec, but didn't) and defines a "Belcarra firmware" pseudo-class.
This patch recognizes that pseudo-class by the GUIDs in those descriptors,
and handles the devices that just use the Zaurus framing.

No, the patch was ok, but I agree it looks strange. It's not very
