not. This patch adds the required settings for it and was successfully
tested with the Netmos device 9900.

In the original code before 181bf1e815a2 the loop was continuing until
it finds the first matching superios[i].io and p->base.
But after 181bf1e815a2 the logic changed and the loop now returns the
pointer to the first mismatched array element which is then used in
get_superio_dma() and get_superio_irq() and thus returning the wrong
value.
Fix the condition so that it now returns the correct pointer.

When the kernel is running in secure boot mode, we lock down the kernel to
prevent userspace from modifying the running kernel image. Whilst this
includes prohibiting access to things like /dev/mem, it must also prevent
access by means of configuring driver modules in such a way as to cause a
device to access or modify the kernel image.
To this end, annotate module_param* statements that refer to hardware
configuration and indicate for future reference what type of parameter they
specify. The parameter parser in the core sees this information and can
skip such parameters with an error message if the kernel is locked down.
The module initialisation then runs as normal, but just sees whatever the
default values for those parameters is.
Note that we do still need to do the module initialisation because some
drivers have viable defaults set in case parameters aren't specified and
some drivers support automatic configuration (e.g. PNP or PCI) in addition
to manually coded parameters.
This patch annotates drivers in drivers/parport/.

When the parport_pc module is removed from the system, all parport
devices are iterated in parport_pc_exit and removed by a call to
parport_pc_unregister_port. Note that some parport devices have its
'struct device' parent, known as port->dev. And when port->dev is a
platform device, it is destroyed in parport_pc_exit too.
Now, when parport_pc_unregister_port is called for a going port,
drv->detach(port) is called for every parport driver in the system.
ppdev can be one of them. ppdev's detach() tears down its per-port
sysfs directory, which established port->dev as a parent earlier.
But since parport_pc_exit kills port->dev parents before unregisters
ports proper, ppdev's sysfs directory has no living parent anymore.
This results in the following warning:
WARNING: CPU: 1 PID: 785 at fs/sysfs/group.c:219 sysfs_remove_group+0x9b/0xa0
sysfs group ffffffff81c69e20 not found for kobject 'parport1'

It is also easily reproducible on qemu with two dummy ports '-parallel
/dev/null -parallel /dev/null'.
So switch the order of killing the two structures. But since port is
freed by parport_pc_unregister_port, we have to remember port->dev
in a local variable.
Perhaps nothing worse than the warning happens thanks to the device
refcounting. We *should* be on the safe side.

We definitely know that only x86 (32-bit) architecture is affected by the issue, so implement a stub instead of the actual check for other architectures.
We also know that motherboard LPT chipset is affected, so the port is either come from
parport_pc_init (when `io' module param is used) or
parport_pc_find_isa_ports (when default LPT ports are probbed: 0x378, 0x278, 0x3bc).
In both cases the port considered as 'legacy' and `dev' member of struct parport is NULL. See also comments for `struct parport' in parport.h

In commit 85747f ("PATCH] parport: add NetMOS 9805 support") Max added
the PCI ID for NetMOS 9805 based on a Debian bug report from 2k4 which
was at the v2.4.26 time frame. The patch made into 2.6.14.
Shortly before that patch akpm merged commit 296d3c783b ("[PATCH] Support
NetMOS based PCI cards providing serial and parallel ports") which made
into v2.6.9-rc1.
Now we have two different entries for the same PCI id.
I have here the NetMos 9805 which claims to support SPP/EPP/ECP mode.
This patch takes Max's entry for titan_1284p1 (base != -1 specifies the
ioport for ECP mode) and replaces akpm's entry for netmos_9805 which
specified -1 (=none). Both share the same PCI-ID (my card has subsystem
0x1000 / 0x0020 so it should match PCI_ANY).
While here I also drop the entry for titan_1284p2 which is the same as
netmos_9815.

Since commit 7106b4e3 ("8250: Oxford Semiconductor Devices") the debug
print of the device id does no longer match the real device if it is
located in the "enum" behind oxsemi_pcie_pport. The reason is that the
code assumes that each id contains one entry in the PCI table.
The fix is to lookup the currently used id from the id-> parameter.

sio_ite_8872_probe() bails out if it detects no-parallel (1S, 2S) or
unknown card.
It doesn't call release_region() on the previously allocated resource
though. This causes
(a) leak of the resource
(b) kernel oops when parport module is removed and /proc/ioports is read. This
is because the string that has been associated to the IO port region
is a static char array inside the already removed module.
Let's call release_region() properly before baling out.

parport_pc_probe_port() creates the own 'parport_pc' device if the
device argument is NULL. Then parport_pc_probe_port() doesn't
initialize the dma_mask and coherent_dma_mask of the device and calls
dma_alloc_coherent with it. dma_alloc_coherent fails because
dma_alloc_coherent() doesn't accept the uninitialized dma_mask:
http://lkml.org/lkml/2009/6/16/150
Long ago, X86_32 and X86_64 had the own dma_alloc_coherent
implementations; X86_32 accepted a device having dma_mask that is not
initialized however X86_64 didn't. When we merged them, we chose to
prohibit a device having dma_mask that is not initialized. I think
that it's good to require drivers to set up dma_mask (and
coherent_dma_mask) properly if the drivers want DMA.

CONFIG_PARPORT_PC_SUPERIO probes for various superio chips by writing
byte sequences to a set of different potential I/O ranges. But the
probed ranges are not exclusive to parallel ports. Some of our boards
just happen to have a watchdog in one of them. Took us almost a week
to figure out why some distros reboot without warning after running
flawlessly for 3 hours. For exactly 170 = 0xAA minutes, that is ...
Fixed by restoring original values after probing. Also fixed too small
request_region() in detect_and_report_it87().

This patch fixes array subscription bugs in the parport_pc driver.
drivers/parport/parport_pc.c: In function ‘parport_irq_probe’:
drivers/parport/parport_pc.c:1589: warning: array subscript is above array bounds
drivers/parport/parport_pc.c: In function ‘parport_pc_probe_port’:
drivers/parport/parport_pc.c:1579: warning: array subscript is above array bounds
The patch also fixes a few other array bugs, which the compiler was
unable to find. Coding style violations are also fixed.

PCI parallel port devices can IRQ share so we should stop them hogging
the line and making a mess on modern PC systems. We know the sharing
side works as the PCMCIA driver has shared the parallel port IRQ for
some time.

Use the 2nd BAR for the oxsemi_840 chip as BAR for base_hi. Tested with:
Parallel controller [0701]: Oxford Semiconductor Ltd VScom 011H-EP1
1 port parallel adaptor [1415:8403] (prog-if 03 [IEEE1284])
This patch is needed to make 'TRISTATE' work with that adaptor.

Wrap PNP probe code in #ifdef CONFIG_PNP. We already do the same for
CONFIG_PCI.
Without this change, we'll have unresolved references to pnp_get_resource()
function when CONFIG_PNP=n. (This is a new interface that's not in mainline
yet.)

Commit f63fd7e299ee13da071ecfce2b90b58c5e1562b1 ("parport_pc: detection
for SuperIO IT87XX POST") only released the IO port region on success,
not when the probe for the IT87XX chip failed.
That caused not only a reserved region to leak, but also caused an oops
when the driver module was unloaded and somebody tried to cat
/proc/ioports - because the string that was assigned to the IO port
region was a static string in the module virtual address area.
