| * | | spi/fsl-espi: disable CONFIG_SPI_FSL_ESPI=m buildJiri Slaby2011-12-071-2/+2

Also some called functions are not exported. So we forbid CONFIG_SPI_FSL_ESPI to be tristate here. The error looks like: drivers/spi/spi_fsl_espi.c: In function 'fsl_espi_bufs': drivers/spi/spi_fsl_espi.c:232: error: 'struct mpc8xxx_spi' has no member named 'len' ...

| * | | | md: take a reference to mddev during sysfs access.NeilBrown2011-12-081-1/+18

And we also take the mddev_lock. However this is not enough. The final mddev_put could have been called and the mddev_delayed_delete is waiting for sysfs to let go so it can destroy the kobj and mddev. In this state there are a lot of changes that should not be attempted. To to guard against this we: - initialise mddev->all_mddevs in on last put so the state can be easily detected. - in md_attr_show and md_attr_store, check ->all_mddevs under all_mddevs_lock and mddev_get the mddev if it still appears to be active. This means that if we get to sysfs as the mddev is being deleted we will get -EBUSY. rdev_attr_store and rdev_attr_show are similar but already have sufficient protection. They check that rdev->mddev still points to mddev after taking mddev_lock. As this is cleared before delayed removal which can only be requested under the mddev_lock, this ensure the rdev and mddev are still alive. Signed-off-by: NeilBrown <neilb@suse.de>
| * | | | md: refine interpretation of "hold_active == UNTIL_IOCTL".NeilBrown2011-12-081-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We like md devices to disappear when they really are not needed. However it is not possible to tell from the current state whether it is needed or not. We can only tell from recent history of changes. In particular immediately after we create an md device it looks very similar to immediately after we have finished with it. So we always preserve a newly created md device until something significant happens. This state is stored in 'hold_active'. The normal case is to keep it until an ioctl happens, as that will normally either activate it, or explicitly de-activate it. If it doesn't then it was probably created by mistake and it is now time to get rid of it. We can also modify an array via sysfs (instead of via ioctl) and we currently treat any change via sysfs like an ioctl as a sign that if it now isn't more active, it should be destroyed. However this is not appropriate as changes made via sysfs are more gradual so we should look for a more definitive change. So this patch only clears 'hold_active' from UNTIL_IOCTL to clear when the array_state is changed via sysfs. Other changes via sysfs are ignored. Signed-off-by: NeilBrown <neilb@suse.de>
| * | | | md/lock: ensure updates to page_attrs are properly locked.NeilBrown2011-11-231-0/+4

However there are two places where we might set or clear page attributes without holding the spinlock. So add the spinlock in those cases. This might be the cause of occasional reports that bits a aren't getting clear properly - theory is that BITMAP_PAGE_PENDING gets lost when BITMAP_PAGE_NEEDWRITE is set or cleared. This is an inconvenience, not a threat to data safety. Signed-off-by: NeilBrown <neilb@suse.de>

But, in some cases (especially with ALC663 & co), some DACs are available only with a later pin and it's assigned to a speaker, and since the driver parses the pins from the lower NID, such a DAC was skipped eventually without assignments. This resulted in a regression, the missing speaker volume control in the new parser. As a workaround for this, now the driver retries the pin->DAC mapping again after restoring the speaker-pins as primary. This is still an ad hoc fix, but it works so far for most of Realtek codecs.

Sending to stable as without this the dummy driver is not terribly useful.

This ended up with the silent output on some HP laptops due to having another GPIO used as external amp control. This patch fixes the problem by checking the max GPIO count and comparing with the given value from DMI entry instead of magic fixed value 4 and 8, and adding a new field to indicate the VREF mute-LED behavior.

In one case, more than 350 ms was required. To allow users to have sound on those platforms, we'll wait up to 500ms for the codec to become ready. As a board may have multiple codecs, with some faster than others to reset, we add a module parameter to inform the driver which codecs should be present.

We rely on get_{idle,iowait}_time functions to retrieve proper data. These functions, however, use usecs_to_cputime to translate micro seconds time to cputime64_t. This is just an alias to usecs_to_jiffies which reduces the data type from u64 to unsigned int and also checks whether the given parameter overflows jiffies_to_usecs(MAX_JIFFY_OFFSET) and returns MAX_JIFFY_OFFSET in that case. When we overflow depends on CONFIG_HZ but especially for CONFIG_HZ_300 it is quite low (1431649781) so we are getting MAX_JIFFY_OFFSET for >3000s! until we overflow unsigned int. Just for reference CONFIG_HZ_100 has an overflow window around 20s, CONFIG_HZ_250 ~8s and CONFIG_HZ_1000 ~2s. This results in a bug when people saw [h]top going mad reporting 100% CPU usage even though there was basically no CPU load. The reason was simply that /proc/stat stopped reporting idle/io_wait changes (and reported MAX_JIFFY_OFFSET) and so the only change happening was for user system time. Let's use nsecs_to_jiffies64 instead which doesn't reduce the precision to 32b type and it is much more appropriate for cumulative time values (unlike usecs_to_jiffies which intended for timeout calculations).
