enabling interrupts which nobody asks it to do (that has been fixed recently in
a number of drivers) and one unusual, with poll_controller() method possibly
causing loss of interrupts due to the interrupt status register being cleared
by a simple read and the interrpupt handler simply storing it, not accumulating.

In active-backup mode, the current bonding code duplicates IGMP
traffic to all slaves, so that switches are up to date in case of a
failover from an active to a backup interface. If bonding then fails
back to the original active interface, it is likely that the "active
slave" switch's IGMP forwarding for the port will be out of date until
some event occurs to refresh the switch (e.g., a membership query).
This patch alters the behavior of bonding to no longer flood
IGMP to all ports, and to issue IGMP JOINs to the newly active port at
the time of a failover. This insures that switches are kept up to date
for all cases.
"GOELLESCH Niels" <niels.goellesch@eurocontrol.int> originally
reported this problem, and included a patch. His original patch was
modified by Jay Vosburgh to additionally remove the existing IGMP flood
behavior, use RCU, streamline code paths, fix trailing white space, and
adjust for style.

Signed-off-by: Jeff Garzik <jeff@garzik.org>
Bonding can erroneously register the same packet_type to receive
ARPs (for use by ARP validation): once at device open time, and once via
sysfs. Since sysfs can change the validate setting (and thus register
or unregister) at any time, a flag is needed to synchronize with device
open in order to avoid double registrations, and the simplest place is
within the packet_type structure itself. Double unregister is not an
issue.

Fix wrong "port" calculations in pdc202xx_{configure_piomode,set_dmamode}()
They were broken for all configurations except one (master device on primary
channel, no other devices) and as a result device settings + PIO/DMA timings
were being programmed into the wrong PCI registers. This could result in
a large variety of problems including data corruption, hangs etc. (depending
on devices used and your luck :-).
ap->port_no ap->devno used PCI registers correct PCI registers
0 0 0x60-0x62 0x60-0x62
0 1 0x62-0x64 0x64-0x66
1 0 0x64-0x66 0x68-0x6a
1 1 0x66-0x68 0x6c-0x6e
Also forward port recent fixes from drivers/ide pdc202xx_old driver:
* fix XFER_MW_DMA0 timings (they were overclocked, use the official ones)
* fix bitmasks for clearing bits of register B:
- when programming DMA mode bit 0x10 of register B was cleared which
resulted in overclocked PIO timing setting (iff PIO0 was used)
- when programming PIO mode bits 0x18 weren't cleared so suboptimal
timings were used for PIO1-4 if PIO0 was previously set (bit 0x10)
and for PIO0/3/4 if PIO1/2 was previously set (bit 0x08)
and finally bump driver version.

pata_legacy fails to detect the disk on my old ISA/VLB 486:
it starts to probe io=0x1f0 ctr=0x3f6 irq=15, complains
loudly about IDENTIFYs timing out, and finally fails.
(Sorry I couldn't capture the kernel's boot messages.)
It turns out that the driver's mapping from io to irq in
legacy_irq[] is wrong: index 0 for io=0x1f0 has irq=15 but
should have irq=14, and index 1 for io=0x170 has irq=14 but
should have irq=15. This is confirmed by a comparison with
include/asm-i386/ide.h:ide_default_irq().
This patch swaps the first two elements in legacy_irq[],
which makes pata_legacy work on my 486.

Replaced check_user_space() + __check_access_register with the new
check_space(). The old functions made wrong assumptions about kernel
and user space when the kernel and user address spaces are switched
(kernel in home space, user in primary/secondary space).
Secondly the user process can switch to the accress register mode if
it is running in primary or secondary mode. In addition it can load
an arbitrary value to the access registers. If any other value than
0 for primary space or 1 for secondary space is loaded and memory
is accessed using the base register related to the access register,
the program should be terminated with a SIGSEGV. To achieve that the
DUALD pointer in the DUCT and the PSALD pointer in the PASTE need
to point to an array of 8 invalid access-list entries to get a
ALEN-translation exception if an invalid alet is used.

For extended error reporting we sometimes have to start an
Sense Subsystem Status request (SNSS). When this request needs
to be recovered for some reason, the recovery request will
fail with 'command reject'.
Our usual recovery procedure will retry the failed request by
creating a new request and chaining the failed request from that
one. SNSS requests, though, must not be chained from anything,
so the recovery request will fail permanently.
Use the default recovery for SNSS request, which will just restart
the original request without further ado.

Fix {nf,ip}_ct_iterate_cleanup unconfirmed list handling:
- unconfirmed entries can not be killed manually, they are removed on
confirmation or final destruction of the conntrack entry, which means
we might iterate forever without making forward progress.
This can happen in combination with the conntrack event cache, which
holds a reference to the conntrack entry, which is only released when
the packet makes it all the way through the stack or a different
packet is handled.
- taking references to an unconfirmed entry and using it outside the
locked section doesn't work, the list entries are not refcounted and
another CPU might already be waiting to destroy the entry
What the code really wants to do is make sure the references of the hash
table to the selected conntrack entries are released, so they will be
destroyed once all references from skbs and the event cache are dropped.
Since unconfirmed entries haven't even entered the hash yet, simply mark
them as dying and skip confirmation based on that.
