Start making the rtc-cmos alarm act more like a oneshot alarm by disabling
that alarm after its IRQ fires. (ACPI hooks are also needed.)
The Linux RTC framework has previously been a bit vague in this area, but
any other behavior is problematic and not very portable. RTCs with full
YYYY-MM-DD HH:MM[:SS] alarms won't have a problem here. Only ones with
partial match criteria, with the most visible example being the PC RTC, get
confused. (Because the criteria will match repeatedly.)
Update comments relating to that oneshot behavior and timezone handling.
(Timezones are another issue that's mostly visible with rtc-cmos. That's
because PCs often dual-boot MS-Windows, which likes its RTC to match local
wall-clock time instead of UTC.)

This adds a basic ds1302 RTC driver, which is basically a cleanup and move
of the in-tree SH SecureEdge5410 code (which is currently located in
arch/sh/board/snapgear/rtc.c) to drivers/rtc.
This aims to be a building block that the M32R and CRIS code can be worked
on top of, so we can get rid of drivers/char/ds1302.c and
arch/cris/arch-v10/drivers/ds1302.c respectively, though more work is
needed for this.

This makes rtc-cmos export its NVRAM, like several other RTC drivers.
It still works within the limits of the current CMOS_READ/CMOS_WRITE calls,
which don't understand how to access multiple register banks. The primary
impact of that limitation is that Linux can't access the uppermost 128
bytes of NVRAM on many systems.
Note that this isn't aiming to be a drop-in replacement for the legacy
/dev/nvram support. (Presumably that has real users, and isn't just
getting carried forward automatically?) Userspace handles more work:
- When userspace code updates NVRAM, that will need to include
updating any platform-specific checksums that may apply.
- No /proc/driver/nvram file will parse and display NVRAM data
according to whichever boot firmware your board expects.
Also minor pnp-related updates: update a comment, remove dead code.

The ser_gigaset ISDN driver was using a mutex in its close() method for
waiting for other running ldisc methods to finish. That's what completions
are for. Incidentally, this also avoids a spurious "BUG: lock held at task

Add support for SPI over SCI pins. SCI is a very simple serial controller

The two S3C SPI master drivers got merged without much review, so I just
noticed that they're doing something that the SPI core code is responsible
for, rather than any adapter driver: they try to register SPI devices.
This removes that support from those drivers so they act normally.
Interestingly, none of the current boards are affected. So it's a net code
shrink with no loss of functionality.

In atmel_spi_next_xfer, xfer can be NULL because the next transfer may
already have been submitted to the PDC (using DMA chaining). This can
cause an oops, since the debug message assumed it was never null. The
fix changes how those debug messages are issued, ensuring that one is
issued each time a transfer is started instead of once per call.
Also, properly indent the "can this transfer be chained" test so it's
not hidden as if it were non-conditional code.

Add support for chained transfers in the atmel_spi driver, letting the DMA
controller switch to the next buffer pair without CPU intervention. This
reduced I/O latencies by about 2% in one bulk I/O test. It should also help
work around several interrelated errata affecting chipselect 0 on at91rm9200
chips.
Almost all of the changes are in the reworked atmel_spi_next_xfer() function.
That's now called with the driver in one of three states:
1. It isn't transferring anything (in which case the first transfer
of the current message is going to be sent)
2. It has finished transfering a non-chainable transfer (in which
case it will go to the next transfer in the message)
3. It has finished transfering a chained transfer (in which case the
next transfer is already queued)
After that it will queue the next transfer if it can be chained.

Don't insert (undesirable) delays between consecutive words (DLYBCT) or when
activating chipselects (DLYBS).
Removing the between-word delays improves the performance of bulk transfers
(such as mtd_dataflash, m25p80, mmc_spi) significantly. In one test, the
improvement was a factor of more than eight!
(The large DLYBCT value came from the legacy at91 SPI driver, and it's not
clear why it used such a huge value.)

Commit edfaa7c36574f1bf09c65ad602412db9da5f96bf
Driver core: convert block from raw kobjects to core devices
This moves the block devices to /sys/class/block. It will create a
flat list of all block devices, with the disks and partitions in one
directory. For compatibility /sys/block is created and contains symlinks
to the disks.
introduced a global disk_type variable in <linux/genhd.h>, causing the
following compile error on Atari:
drivers/block/ataflop.c:93: error: conflicting types for 'disk_type'
include/linux/genhd.h:21: error: previous declaration of 'disk_type' was here
Rename the local disk_type variable in drivers/block/ataflop.c to
atari_disk_type, to avoid the conflict.

Standardize the temperature units to millidegrees C for the two sensor
conversion routines. Previously the routines were,
w1_DS18B20_convert_temp degrees C
w1_DS18S20_convert_temp millidegrees C
Unfortunately this will break any program using the ds18b20 value as it
will now be 1000 times bigger. Fortunately there can't be that many users
out there, or some of these bugs will have been fixed by now, such as the
negative C error (see previous patch) that makes me think the ds18b20 is
the better choice to change because of the current bugs.

Fix two N_TTY line discipline issues related to resuming a stopped TTY
(typically done with ctrl-S):
1) Fix handling of character that resumes a stopped TTY (with IXANY)
With "stty ixany", the TTY line discipline would lose the first character
after the stop, so typing, for example, "hi^Sthere" resulted in "hihere"
(the 't' would cause the resume after ^S, but it would then be thrown away
rather than processed as an input character). This was inconsistent with
the behavior of other Unix systems.
2) Fix interrupt signal (e.g. ctrl-C) behavior in stopped TTYs
With "stty -ixany" (often the default), interrupt signals were ignored
in a stopped TTY until the TTY was resumed with the start char (typically
ctrl-Q), which was inconsistent with the behavior of other Unix systems.

Fix wrong netmos 9855 serial port configuration.
On loading only one serial port was present and it wasn't working. After
looking in the data sheet I realized that the base address was wrong. For
further reference here is lspci and relevant dmesg output:
