machine_is() was always returning 0 when used in a module, because
we weren't exporting the machine definitions. This was why sound
wasn't working on powermacs when CONFIG_SND_POWERMAC=m. Original
fix from Ben Herrenschmidt, further fixed by me.

The current PCI error recovery system keeps track of the number of PCI card
resets, and refuses to bring a card back up if this number is too large.
The goal of doing this was to avoid an infinite loop of resets if a card is
obviously dead. However, if the failures are rare, but the machine has a
high uptime, this mechanism might still be triggered; this is too harsh.
This patch will avoids this problem by decrementing the fail count after an
hour. Thus, as long as a pci card BSOD's less than 6 times an hour, it
will continue to be reset indefinitely. If it's failure rate is greater
than that, it will be taken off-line permanently.
This patch is larger than it might otherwise be because it changes
indentation by removing a pointless while-loop. The while loop is not
needed, as the handler is invoked once fo each event (by schedule_work());
the loop is leftover cruft from an earlier implementation.

In some crash scenarios, the kexec CPU is not responding to an IPI sent by
secondary CPU after init thread is forked, causing the system to drop into
xmon during kdump boot. This problem can be reproduced each time when the
debugger is enabled and soft-reset is used to invoke kdump boot. The first
CPU sends an IPI - setting the IPI priority for all secondary cpus
(xics_cause_ipi()). But some CPUs will enter into the xmon via soft-reset,
i.e, not executing xics_ipi_action(). Hence, IPI is not cleared. When
exited from the debugger, one of these CPUs could become the primary kexec
CPU. Since the IPI is not cleared, causing this issue in kdump boot. This
patch clears and EOI IPI for kexec CPU as well before the kdump boot
started.

We've seen several bugs caused by interrupt weirdness in the kdump kernel.
Panicking from an interrupt handler means we fail to EOI the interrupt, and
so the second kernel never gets that interrupt ever again. We also see hangs
on JS20 where we take interrupts in the second kernel early during boot.
This patch fixes both those problems, and although it adds more code to the
crash path I think it is the best solution.

The new i2c implementation for PowerMac has a regression that causes the
hardware to go out of state when probing non-existent devices. While
fixing that, I also found & fixed a couple of other corner cases. This
fixes booting with a pbbuttons version that scans the i2c bus for an LMU
controller among others. Tested on a dual G5 with thermal control (which
has heavy i2c activity) with no problem so far.

Turn on the DART already at 1GB. This is needed because of crippled
devices in some systems, i.e. Airport Extreme cards, only supporting
30-bit DMA addresses.
Otherwise, users with between 1 and 2GB of memory will need to manually
enable it with iommu=force, and that's no good.
Some simple performance tests show that there's a slight impact of
enabling DART, but it's in the 1-3% range (kernel build with disk I/O
as well as over NFS).
iommu=off can still be used for those who don't want to deal with the
overhead (and don't need it for any devices).

any user can read the encryption keys. The fix is trivial and should

The room for the names in bcm43xx_priv_wx_args[] are IFNAMSIZ long and
IFNAMSIZ is defined as 16, so the names in bcm43xx_priv_wx_args should
be 15 characters (16 including the trailing \0). This patch fixes that

This fixes a spinlock recursion on receiving a reassoc request.
On reassoc, the softmac calls back into the driver. This results in a
driver lock recursion. This schedules the assoc workqueue, instead
of calling it directly.
Probably, we should defer the _whole_ management frame processing
to a tasklet or workqueue, because it does several callbacks into the driver.
That is dangerous.
This fix should go into linus's tree, before 2.6.17 is released, because it
is remote exploitable (DoS by crash).

2.6.17-rc1 changed the title for the entry CONFIG_NET_RADIO. I
personally disagree with this change and want it reverted. Patch for
2.6.17-rc1.
Rationale : WIRELESS_EXT is an invisible option. Therefore,
the only way for a user to enable it is via NET_RADIO. Some users need
to do that for out-of-tree drivers. Therefore it should be mentionned
in the title of the option.
Rationale2 : the option just below is called "Wireless
Extension API over RtNetlink". Some users may confuse this option for
the main "Wireless Extension" option. Therefore reverting this change
help disambiguate the relation between those two options.
