2009-12-10vfs: Implement proper O_SYNC semanticsChristoph Hellwig
While Linux provided an O_SYNC flag basically since day 1, it took until Linux 2.4.0-test12pre2 to actually get it implemented for filesystems, since that day we had generic_osync_around with only minor changes and the great "For now, when the user asks for O_SYNC, we'll actually give O_DSYNC" comment. This patch intends to actually give us real O_SYNC semantics in addition to the O_DSYNC semantics. After Jan's O_SYNC patches which are required before this patch it's actually surprisingly simple, we just need to figure out when to set the datasync flag to vfs_fsync_range and when not. This patch renames the existing O_SYNC flag to O_DSYNC while keeping it's numerical value to keep binary compatibility, and adds a new real O_SYNC flag. To guarantee backwards compatiblity it is defined as expanding to both the O_DSYNC and the new additional binary flag (__O_SYNC) to make sure we are backwards-compatible when compiled against the new headers. This also means that all places that don't care about the differences can just check O_DSYNC and get the right behaviour for O_SYNC, too - only places that actuall care need to check __O_SYNC in addition. Drivers and network filesystems have been updated in a fail safe way to always do the full sync magic if O_DSYNC is set. The few places setting O_SYNC for lower layers are kept that way for now to stay failsafe. We enforce that O_DSYNC is set when __O_SYNC is set early in the open path to make sure we always get these sane options. Note that parisc really screwed up their headers as they already define a O_DSYNC that has always been a no-op. We try to repair it by using it for the new O_DSYNC and redefinining O_SYNC to send both the traditional O_SYNC numerical value _and_ the O_DSYNC one.

2009-12-09nvram: Fix missing smp_lock.h in nvramFrederic Weisbecker
The bkl has been removed from nvram_llseek() and smp_lock.h was removed because another patch in the same tree zapped the remaining usage of bkl in the same file. But this patch must have been excluded later, then we still need the smp_lock.h headers for the bkl use in nvram_open(). This fixes the following build error: drivers/char/nvram.c: In function ‘nvram_open’: drivers/char/nvram.c:332: erreur: implicit declaration of function ‘lock_kernel’ drivers/char/nvram.c:339: erreur: implicit declaration of function ‘unlock_kernel’ make[2]: *** [drivers/char/nvram.o] Erreur 1 make[1]: *** [drivers/char] Erreur 2 make: *** [drivers] Erreur 2 Signed-off-by: Frederic Weisbecker <fweisbec@gmail.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2009-12-09hwmon: (adt7475) Handle alternative pin functionsJean Delvare
The TACH4 pin can be used for other functions, so fan4 may not always be available. Likewise, the PWM2 pin can be used for ALERT output, in which case pwm2 is not available For the ADT7490, the +2.5 Vin pin may also be used for other functions, in which case in0 is not available.

2009-12-09hwmon: (adt7475) Move sysfs files removal to a separate functionJean Delvare
Move sysfs files removal to a separate function. The code is common to the device probing error path and the standard device removal path. As it will grow with future driver development, this avoids code duplication.

2009-12-09hwmon: (adt7475) Add support for the ADT7490Jean Delvare
Add support for the Analog Devices ADT7490 chip. This chip is largely compatible with the ADT7473 and ADT7475, with additional features. In particular, it has 6 voltage inputs instead of 2.

2009-12-09hwmon: (adt7475) New documentationJean Delvare
New documentation for the adt7475 driver, based on the adt7473 driver documentation. It is IMHO much more useful that the previous documentation which was essentially redundant with sysfs-interface.

2009-12-09hwmon: (adt7475) Add support for the ADT7473Jean Delvare
Add support for the ADT7473 to the adt7475 driver, and mark the adt7473 driver for removal. The ADT7473 and ADT7475 chips are almost the same chip and essentially compatible, so there's no point in having separate drivers for them.

2009-12-09hwmon: (f71882fg) Add support for the f71889fg (version 2)Hans de Goede
This adds support for the Fintek f71889fg to the f71882fg driver, many thanks to Gerd v. Egidy for providing (remote) access to a machine which such an ic. Note that this bit of the patch: - val = SENSORS_LIMIT(val, 0, 255); + + if (data->type == f71889fg) + val = SENSORS_LIMIT(val, -128, 127); + else + val = SENSORS_LIMIT(val, 0, 127); Changes behaviour for already supported models, the new behaviour is correct as the already supported models have bit 7 of the involved registers fixed at 0, so the previous behaviour which allowed setting temp zone limits > 127 was not correct.

2009-12-09hwmon: (f71882fg) Fix sysfs file removalHans de Goede
There is a bug in the old sysfs file removal, as it uses fxxxx_in_temp_attr to remove the in and temp sysfs attributes, but fxxxx_in_temp_attr has temp#_alarm, where as f71858fg_in_temp_attr has temp#_max_alarm, so the temp#_max_alarm attributes for the f71858fg never get removed. This patch fixes this by doing the sysfs removal exactly the same way as the creation instead of being (too) clever, this will also avoid similar bugs in the future.

2009-12-09hwmon: (f71882fg) Cleanup sysfs attr creation 2/2Hans de Goede
This patch merges the f71882fg_auto_pwm_attr array into the fxxxx_fan_attr resp. fxxxx_auto_pwm_attr array, as the f71882fg_auto_pwm_attr array was merely extending these 2 with entries for a 4th fan, it also makes these 2 arrays 2 dimensional so that the rest of the code can choose to add attr for 3 or 4 fans without needing to know the nr of attr per fan.

2009-12-09hwmon: (f71882fg) Cleanup sysfs attr creation 1/2Hans de Goede
This patch makes a number of cleanups to the sysfs attr creation in the f71882fg driver, this is a preparation patch for adding f71889fg support: * Add some comments to explain why some models need separate sysfs attr arrays for in / temp / fan / pwm * Rename a number of sysfs attr arrays to make their function clearer * Move the pwm#_auto_channels_temp attribute from the common to all models fan attr array to the per model auto mode pwm attr arrays, so that all the auto mode pwm attr are grouped together, and thus can be left out on models where we don't support auto pwm mode * Put fan_beep attr in their own array, so that only auto mode pwm attr remain in the per model pwm sysfs attr arrays. * Put the 4th special fan input for the f8000 in its own array, so that only auto mode pwm attr remain in the per model pwm sysfs attr arrays.
