The SUN_AURORA driver:
- has been marked as BROKEN for more than two years and
- is still marked as BROKEN.
Drivers that had been marked as BROKEN for such a long time seem to be
unlikely to be revived in the forseeable future.
But if anyone wants to ever revive this driver, the code is still
present in the older kernel releases.

move_native_irqs tries to do the right thing when migrating irqs
by disabling them. However disabling them is a software logical
thing, not a hardware thing. This has always been a little flaky
and after Ingo's latest round of changes it is guaranteed to not
mask the apic.
So this patch fixes move_native_irq to directly call the mask and
unmask chip methods to guarantee that we mask the irq when we
are migrating it. We must do this as it is required by
all code that call into the path.
Since we don't know the masked status when IRQ_DISABLED is
set so we will not be able to restore it. The patch makes the code
just give up and trying again the next time this routing is called.

The problem: After moving an interrupt when is it safe to teardown
the data structures for receiving the interrupt at the old location?
With a normal pci device it is possible to issue a read to a device
to flush all posted writes. This does not work for the oldest ioapics
because they are on a 3-wire apic bus which is a completely different
data path. For some more modern ioapics when everything is using
front side bus delivery you can flush interrupts by simply issuing a
read to the ioapic. For other modern ioapics emperical testing has
shown that this does not work.
So it appears the only reliable way to know the last of the irqs from an
ioapic have been received from before the ioapic was reprogrammed is to
received the first irq from the ioapic from after it was reprogrammed.
Once we know the last irq message has been received from an ioapic
into a local apic we then need to know that irq message has been
processed through the local apics.

The code in io_apic.c and in i8259.c currently hardcode the same
vector for the timer interrupt so there is no reason for a special

Currently assign_irq_vector works mostly by side effect and returns
the results of it's changes to the caller. Which makes for a lot of
arguments to pass/return and confusion as to what to do if you need
the status but you aren't calling assign_irq_vector.
This patch stops returning values from assign_irq_vector that can be
retrieved just as easily by examining irq_cfg, and modifies the
callers to retrive those values from irq_cfg when they need them.

Currently the io_apic.c has several parallel arrays for different
kinds of data that can be know about an irq. The parallel arrays
make the code harder to maintain and make it difficult to remove
the static limits on the number of the number of irqs.
This patch pushes irq_data and irq_vector into a irq_cfg array and
updates the code to use it.

This patch updates the users of NR_IRQ_VECTORS to use NR_IRQs instead
so that NR_IRQ_VECTORS can be removed.

If we have an irq that comes from multiple io_apic pins the FINAL action
(which is io_apic_sync or nothing) needs to be called for every entry or
else if the two pins come from different io_apics we may not wait until
after the action happens on the io_apic.

For some reason the code has been picking TARGET_CPUS when asked to
set the affinity to an empty set of cpus. That is just silly it's
extra work. Instead if there are no cpus to set the affinity to we
should just give up immediately. That is simpler and a little more
intuitive.

Currently we have two routines that do practically the same thing
setup_IO_APIC_irq and io_apic_set_pci_routing. This patch makes
setup_IO_APIC_irq the common factor of these two previous routines.
For setup_IO_APIC_irq all that was needed was to pass the trigger
and polarity to make the code a proper subset of io_apic_set_pci_routing.
Hopefully consolidating these two routines will improve maintenance
there were several differences that simply appear to be one routine
or the other getting it wrong.

Uwe Bugla reports that he cannot mount a floppy drive any more, and Jiri
Slaby bisected it down to this commit.
Benjamin LaHaise also points out that this is a big hot-path, and that
interrupt delivery while idle is very common and should not go through
all these expensive gyrations.

TEXT_OFFSET
aware
Since TEXT_OFFSET is meant to determine RAM location for kernel use,
itshould affect .data and .bss initial mapping in the XIP case.
Otherwise a XIP kernel would crash if TEXT_OFFSET gets somewhat larger
than 2MB.
Corresponding code is also moved up a bit to be near the similar .text
mapping code making the whole a bit more straight forward to understand.

Since commit 2552fc27ff79b10b9678d92bcaef21df38bb7bb6 XIP kernels failed
to boot because (_end - PAGE_OFFSET - 1) is much smaller than the size
of the kernel text and data in the XIP case, causing the kernel not to
be entirely mapped.
Even in the non-XIP case, the use of (_end - PAGE_OFFSET - 1) is wrong
because it produces a too large value if TEXT_OFFSET is larger than 1MB.
Finally the original code was performing one loop too many.
Let's break the loop when the section pointer has passed the last byte
of the kernel instead.

This patch (as859) makes the default USB autosuspend delay a module
parameter of usbcore. By setting the delay value at boot time, users
will be able to prevent the system from autosuspending devices which
for some reason can't handle it.
The patch also stores the autosuspend delay as a per-device value. A
later patch will allow the user to change the value, tailoring the
delay for each individual device. A delay value of 0 will prevent
autosuspend.

This patch (as856) attempts to improve the performance of uhci-hcd by
removing the asynchronous skeleton Queue Headers. They don't contain
any useful information but the controller has to read through them at
least once every millisecond, incurring a non-zero DMA overhead.
Now all the asynchronous queues are combined, along with the period-1
interrupt queue, into a single list with a single skeleton QH. The
start of the low-speed control, full-speed control, and bulk sublists
is determined by linear search. Since there should rarely be more
than a couple of QHs in the list, the searches should incur a much
smaller total load than keeping the skeleton QHs.
