2009-06-18isofs: let mode and dmode mount options override rock ridge mode settingJan Kara
So far, permissions set via 'mode' and/or 'dmode' mount options were effective only if the medium had no rock ridge extensions (or was mounted without them). Add 'overriderockmode' mount option to indicate that these options should override permissions set in rock ridge extensions. Maybe this should be default but the current behavior is there since mount options were created so I think we should not change how they behave.

2009-06-18ext3: make sure inode is deleted from orphan list after truncateJan Kara
As Ted pointed out, it can happen that ext3_truncate() returns without removing inode from orphan list. This way we could in some rare cases (like when we get ENOMEM from an allocation in ext3_truncate called because of failed ext3_write_begin) leave the inode on orphan list and that triggers assertion failure on umount. So make ext3_truncate() always remove inode from in-memory orphan list.

2009-06-18ext3: fix chain verification in ext3_get_blocks()Jan Kara
Chain verification in ext3_get_blocks() has been hosed since it called verify_chain(chain, NULL) which always returns success. As a result readers could in theory race with truncate. On the other hand the race probably cannot happen with the current locking scheme, since by the time ext3_truncate() is called all the pages are already removed and hence get_block() shouldn't be called on such pages...

ext2.txt says that dirs can have 32,768 subdirs, but the actual value of EXT2_LINK_MAX is 32000. ext3 is the same, but the doc does not mention it.

2009-06-18ext2: Do not update mtime of a moved directoryJan Kara
One of our users is complaining that his backup tool is upset on ext2 (while it's happy on ext3, xfs, ...) because of the mtime change. The problem is: mkdir foo mkdir bar mkdir foo/a Now under ext2: mv foo/a foo/b changes mtime of 'foo/a' (foo/b after the move). That does not really make sense and it does not happen under any other filesystem I've seen. More complicated is: mv foo/a bar/a This changes mtime of foo/a (bar/a after the move) and it makes some sense since we had to update parent directory pointer of foo/a. But again, no other filesystem does this. So after some thoughts I'd vote for consistency and change ext2 to behave the same as other filesystems. Do not update mtime of a moved directory. Specs don't say anything about it (neither that it should, nor that it should not be updated) and other common filesystems (ext3, ext4, xfs, reiserfs, fat, ...) don't do it. So let's become more consistent. Spotted by ronny.pretzsch@dfs.de, initial fix by Jörn Engel.

2009-06-18gpio: pca953x: Get platform_data from OpenFirmwareNate Case
On OpenFirmware platforms, it makes the most sense to get platform_data from the device tree. Make an attempt to translate OF node properties into platform_data struct before bailing out. Note that the implementation approach taken differs from other device drivers that make use of device tree information. This is because I2C chips are already registered automatically by of_i2c, so we can get by with a small translator function in the driver.

2009-06-18rtc: add stand-alone driver for RX8025 chipWolfgang Grandegger
Add support for the Epson RX-8025SA/NB RTC chips. It includes support for alarms, periodic interrupts (1 Hz) and clock precision adjustment. For clock precision adjustment, the SYSFS file "clock_adjust_ppb" gets created in "/sys/class/rtc/rtcX/device". It permits to set and get the clock adjustment in ppb (parts per billion), e.g.: # echo -183000 > /sys/class/rtc/rtc0/device/clock_adjust_ppb # cat /sys/class/rtc/rtc0/device/clock_adjust_ppb -183000 This allows to compensate temperature dependent clock drifts. According to the RX8025 SA/NB application manual the frequency and temperature characteristics can be approximated using the following equation: df = a * (ut - t)**2 df: Frequency deviation in any temperature a : Coefficient = (-35 +-5) * 10**-9 ut: Ultimate temperature in degree = +25 +-5 degree t : Any temperature in degree Signed-off-by: Wolfgang Grandegger <wg@grandegger.com> Signed-off-by: Sergei Poselenov <sposelenov@emcraft.com> Signed-off-by: Yuri Tikhonov <yur@emcraft.com> Signed-off-by: Dmitry Rakhchev <rda@emcraft.com> Signed-off-by: Matthias Fuchs <matthias.fuchs@esd.eu> Acked-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Alessandro Zummo <a.zummo@towertech.it> Cc: David Brownell <david-b@pacbell.net> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2009-06-18rtc: rtc-ds1742 nvram attribute fixTorsten Ertbjerg Rasmussen
The RTC driver for ds1742 / ds1743 uses a static nvram attribute. This patch replaces this static attribute with one nvram attribute for each ds174x registered. The nvram size is not the same for all types of ds174x. The nvram size is accessible as the file size of the nvram attribute in sysfs. With only a single nvram attribute, this file size will be incorrect if more than one type of ds174x is present on a system. See the comment in the removed code below.

2009-06-18epoll: fix nested calls supportDavide Libenzi
This fixes a regression in 2.6.30. I unfortunately accepted a patch time ago, to drop the "current" usage from possible IRQ context, w/out proper thought over it. The patch switched to using the CPU id by bounding the nested call callback with a get_cpu()/put_cpu(). Unfortunately the ep_call_nested() function can be called with a callback that grabs sleepy locks (from own f_op->poll()), that results in epic fails. The following patch uses the proper "context" depending on the path where it is called, and on the kind of callback. This has been reported by Stefan Richter, that has also verified the patch is his previously failing environment.

2009-06-17mfd: early init for MFD running regulatorsSamuel Ortiz
For MFDs running regulator cores, we really want them to be brought up early during boot. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com> Acked-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Mike Rapoport <mike@compulab.co.il>
2009-06-17mfd: fix tmio related warningsSamuel Ortiz
We can not have .driver_data as const since platform_set_drvdata() doesnt take a const. The hclk mmc_data field can be const though. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

2009-06-17mfd: asic3: add clock handling for MFD cellsPhilipp Zabel
Since ASIC3 has to work on both PXA and S3C and since their struct clk implementations differ, we can't register out clocks with the clkdev mechanism (yet?). For now we have to keep clock handling internal to this driver and enable/disable the clocks via the mfd_cell->enable/disable functions.

2009-06-17mfd: add PCAP driverDaniel Ribeiro
The PCAP Asic as present on EZX phones is a multi function device with voltage regulators, ADC, touch screen controller, RTC, USB transceiver, leds controller, and audio codec. It has two SPI ports, typically one is connected to the application processor and another to the baseband, this driver provides read/write functions to its registers, irq demultiplexer and ADC queueing/abstraction. This chip is used on a lot of Motorola phones, it was manufactured by TI as a custom product with the name PTWL93017, later this design evolved into the ATLAS PMIC from Freescale (MC13783).

2009-06-17mfd: add U300 AB3100 core supportLinus Walleij
This adds a core driver for the AB3100 mixed-signal circuit found in the ST-Ericsson U300 series platforms. This driver is a singleton proxy for all accesses to the AB3100 sub-drivers which will be merged on top of this one, RTC, regulators, battery and system power control, vibrator, LEDs, and an ALSA codec.
