Solves http://bugzilla.kernel.org/show_bug.cgi?id=11127
The old rtc.c driver did it and some drivers (like rtc-sh) do it in their
release function, though they should not -- because they should provide
the irq_set_state op and the rtc framework itself should care about it.
This patch makes it do so.
I am aware that some drivers, like rtc-sh, handle userspace PIE sets in
their ioctl op (instead of having the framework call the op), exporting
the irq_set_state op at the same time. The logic in rtc_irq_set_state
should make sure it doesn't matter and the driver should not need to care
stopping periodic interrupts in its release routine any more.
The correct way, in my opinion, should be this:
1) The driver provides the irq_set_state op and does not care closing the
interrupts in its release op.
2) If the driver does not provide the op and handles PIE in the ioctl op, it's
reponsible for closing them in its release op.
3) Something similar for other IRQs, like UIE -- if there's no in-kernel API
like irq_set_state, handle it in ioctl and release ops. The framework will
be responsible either for everything or for nothing. (This will probably
change later.)

init/main.c:636: warning: passing argument 1 of `virt_to_phys' makes pointer from integer without a cast
For now, kill the warning by explicitly casting initrd_start to `void *', as

Paul pointed out two incorrect read barriers in the marker handler code in
the path where multiple probes are connected. Those are ordering reads of
"ptype" (single or multi probe marker), "multi" array pointer, and "multi"
array data access.
It should be ordered like this :
read ptype
smp_rmb()
read multi array pointer
smp_read_barrier_depends()
access data referenced by multi array pointer
The code with a single probe connected (optimized case, does not have to
allocate an array) has correct memory ordering.
It applies to kernel 2.6.26.x, 2.6.25.x and linux-next.

form a single sched domain, the largest sched_relax_domain_level among
those should be used. But when top_cpuset's sched_load_balance is
set, its sched_relax_domain_level is used regardless other sub-cpusets'.
This patch fixes it by walking the cpuset hierarchy to find the largest

On HPPA there exists some older GSC graphics cards, which need special
graphic-card-BIOS patching to become supported. Since we don't have yet
implemented the patching, it's better to detect such cards in advance,
inform to the user that there are known problems and to not activate the
card.
Problematic GSC cards and BIOS versions are:
* Hyperdrive/Hyperbowl (A4071A) graphics card series:
* ID = 0x2BCB015A (Version 8.04/8)
* ID = 0x2BCB015A (Version 8.04/11)
* Thunder 1 VISUALIZE 48 card:
* ID = 0x2F23E5FC (Version 8.05/9)
* Thunder 2 VISUALIZE 48 XP card:
* ID = 0x2F8D570E (Version 8.05/12)
* Some Hyperion and ThunderHawk GSC cards

Bug report from Steven Jan Springl:
Issuing the following command causes a kernel oops:
tc qdisc add dev eth0 handle ffff: ingress
The problem mostly stems from all of the special case handling of
ingress qdiscs.
So, to fix this, do the grafting operation the same way we do for TX
qdiscs. Which means that dev_activate() and dev_deactivate() now do
the "qdisc_sleeping <--> qdisc" transitions on dev->rx_queue too.
Future simplifications are possible now, mainly because it is
impossible for dev_queue->{qdisc,qdisc_sleeping} to be NULL. There
are NULL checks all over to handle the ingress qdisc special case
that used to exist before this commit.
