| | | | | | | | | | | | | | | | | | Add support for the hwmon part of the Fintek F71858FG superio IC to the f71882fg driver.

| * hwmon: (f71882fg) Add temp#_fault sysfs attr for f8000Hans de Goede2009-06-15
| | | | | | | | | | | | | | | | | | While working on f71852fg support I noticed that the f8000 sysfs attr table was missing entries for temp#_fault, which the f8000 does have and which we were already reading.

| * hwmon: (f71882fg) Sanity check f8000 pwm settingsHans de Goede2009-06-15
| | | | | | | | | | | | | | | | | | | | | | | | We depend up on the pwm_enable register (0x96) not containing any reserved settings in various places. We were already checking to make sure there were no reserved settings in the register for the f71862fg, this patch adds the same checking for the f8000, while at it it also moves the code to a more apropriate place so we don't need to check if the fan/pwm part of the IC is enabled twice.

| * hwmon: (f71882fg) Cleanup f8000 pwm handlingHans de Goede2009-06-15
| | | | | | | | | | | | | | | | | | | | | | | | Currently we are using separate per model sysfs attr for the 3th pwm, because the 3th pwm of the f8000 only has automatic mode and not manual mode. Doing things this way was getting in the way for adding f71858fg support, so this patch makes the pwm attr identical for all models, and instead adds a check to store_pwm_enable() disallowing setting the 3th pwm to manual mode on a f8000 IC.

| * hwmon: PCI quirk for hwmon access on MSI MS-7031 boardJean Delvare2009-06-15
| | | | | | | | | | | | | | | | | | | | | | | | | | The MSI MS-7031 is based on an ATI IXP300 south bridge. On this south bridge, accessible I/O ports must be enabled explicitly. Unfortunately the BIOS forgets to enable access to the hardware monitoring chip I/O ports, so hardware monitoring fails. Add a quirk enabling access to the required ports (0x295-0x296). This is exactly what MSI's own hardware monitoring application is doing, so it has to be the right way. Signed-off-by: Jean Delvare <khali@linux-fr.org>

* | | printk: add KERN_DEFAULT loglevel to print_modules()Linus Torvalds2009-06-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several WARN_ON() messages omit the '\n' at the end of the string, which is a simple (and understandable) error. The next line printed after that warning line is usually the current module list, and that printk does not have a log-level marker - resulting in one long mixed-up line. Adding this loglevel marker will now avoid this unreadable mess. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* | | printk: Add KERN_DEFAULT printk log-levelLinus Torvalds2009-06-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a KERN_DEFAULT loglevel marker, for when you cannot decide which loglevel you want, and just want to keep an existing printk with the default loglevel. The difference between having KERN_DEFAULT and having no log-level marker at all is two-fold: - having the log-level marker will now force a new-line if the previous printout had not added one (perhaps because it forgot, but perhaps because it expected a continuation) - having a log-level marker is required if you are printing out a message that otherwise itself could perhaps otherwise be mistaken for a log-level.

* | | printk: clean up handling of log-levels and newlinesLinus Torvalds2009-06-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It used to be that we would only look at the log-level in a printk() after explicit newlines, which can cause annoying problems when the previous printk() did not end with a '\n'. In that case, the log-level marker would be just printed out in the middle of the line, and be seen as just noise rather than change the logging level. This changes things to always look at the log-level in the first bytes of the printout. If a log level marker is found, it is always used as the log-level. Additionally, if no newline existed, one is added (unless the log-level is the explicit KERN_CONT marker, to explicitly show that it's a continuation of a previous line).

Timers firing on busy CPUs are not migrated. While migrating hrtimers, care should be taken to check if migrating a hrtimer would result in a latency or not. So we compare the expiry of the hrtimer with the next timer interrupt on the target cpu and migrate the hrtimer only if it expires *after* the next interrupt on the target cpu. So, added a clockevents_get_next_event() helper function to return the next_event on the target cpu's clock_event_device.
