Here's the big tty/serial driver pull request for 3.14-rc1
There are a number of n_tty fixes and cleanups, and some serial driver
bugfixes, and we got rid of one obsolete driver, making this series
remove more lines than added, always a nice surprise.
All of these have been in linux-next with no reports of issues.

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.

ZTWO_VADDR() converts from physical to virtual I/O addresses, so it should
return "void __iomem *" instead of "unsigned long".
This allows to drop several casts, but requires adding a few casts to
accomodate legacy driver frameworks that store "unsigned long" I/O
addresses.

Pull DMA mask updates from Russell King:
"This series cleans up the handling of DMA masks in a lot of drivers,
fixing some bugs as we go.
Some of the more serious errors include:
- drivers which only set their coherent DMA mask if the attempt to
set the streaming mask fails.
- drivers which test for a NULL dma mask pointer, and then set the
dma mask pointer to a location in their module .data section -
which will cause problems if the module is reloaded.
To counter these, I have introduced two helper functions:
- dma_set_mask_and_coherent() takes care of setting both the
streaming and coherent masks at the same time, with the correct
error handling as specified by the API.
- dma_coerce_mask_and_coherent() which resolves the problem of
drivers forcefully setting DMA masks. This is more a marker for
future work to further clean these locations up - the code which
creates the devices really should be initialising these, but to fix
that in one go along with this change could potentially be very
disruptive.
The last thing this series does is prise away some of Linux's addition
to "DMA addresses are physical addresses and RAM always starts at
zero". We have ARM LPAE systems where all system memory is above 4GB
physical, hence having DMA masks interpreted by (eg) the block layers
as describing physical addresses in the range 0..DMAMASK fails on
these platforms. Santosh Shilimkar addresses this in this series; the
patches were copied to the appropriate people multiple times but were
ignored.
Fixing this also gets rid of some ARM weirdness in the setup of the
max*pfn variables, and brings ARM into line with every other Linux
architecture as far as those go"

Remove messy dependencies from PARPORT_PC by having it depend on one
Kconfig symbol (ARCH_MIGHT_HAVE_PC_PARPORT) and having architectures
which need it, select ARCH_MIGHT_HAVE_PC_PARPORT in arch/*/Kconfig.
New architectures are unlikely to need PARPORT_PC, so this avoids
having an ever growing list of architectures to exclude. Those
architectures which do select ARCH_MIGHT_HAVE_PC_PARPORT in this
patch are the ones which have an asm/parport.h (or use the generic

To allow parport_serial to handle the card the same PCI ids are blacklisted
in 8250_pci.c using the existing software blacklist mechanism.
The blacklist array is also renamed because it now covers this new use
case.
Since the two serial ports are auto-detected as XScale instead of 16550A
clones, we also add a quirk to 8250_pci.c to skip autodetection and set the
correct port type.

Outside of a few minor driver core changes, we ended up with the
following different subsystem and core changes as well, due to
interdependancies on the driver core:
- hyperv driver updates
- drivers/memory being created and some drivers moved into it
- extcon driver subsystem created out of the old Android staging switch
driver code
- dynamic debug updates
- printk rework, and /dev/kmsg changes
All of this has been tested in the linux-next releases for a few weeks

module_param(bool) used to counter-intuitively take an int. In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.
It's time to remove the int/unsigned int option. For this version
it'll simply give a warning, but it'll break next kernel version.

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.

Timedia/SUNIX PCI cards with both serial and parallel ports are

that support into parport_serial allows using both types of ports at the

Add I/O based support for serial and parallel ports of the following
chips:
Vendor: Moschip (0x9710)
Parts (device IDs)
* 9900 (0x9900)
* 9904 (0x9904
* 9901 (0x9912, also sold as 9912)
* 9922 (0x9922)
On all chips but the 9900, a single port is provided per PCI subdevice
(subvendor-ID 0xA000, subdevice-IDs 0x1000 for serial, 0x2000 for
parallel with proper class codes). In cascading configurations, the
9900 provides two devices per subdevice, with subvendor-ID 0xA000 and
subdevice-IDs 0x30ps where p is the number of parallel ports and s the
number of serial ports.
Basic testing was only done on the serial part of a 9912 to the point
where it can be used for a serial kernel console, and advanced features
are completely untested. It is possible to reduce functionality of the
chips by adding a configuration EEPROM, and the datasheet [1] is
inconsistent w.r.t subdevices in the 4s+2s1p and 2s1p+4s
configurations. The subdevice-ID 0x3012 should likely read 0x3011 with
a serial port in function 3, which would be consistent with the BAR
layouts. For now, the drivers ignore subdevices with ID 0x1000 and no
class code.
The parallel ports are integrated in parport_serial even for purely
parallel parts to reduce the footprint of the patch.
