2007-07-03SLUB: Make lockdep happy by not calling add_partial with interrupts enabled ↵Christoph Lameter
during bootstrap If we move the local_irq_enable() to the end of the function then add_partial() in early_kmem_cache_node_alloc() will be called with interrupts disabled like during regular operations. This makes lockdep happy.

2007-07-03NTP: remove clock_was_set() call to prevent deadlockThomas Gleixner
The clock_was_set() call in seconds_overflow() which happens only when leap seconds are inserted / deleted is wrong in two aspects: 1. it results in a call to on_each_cpu() with interrupts disabled 2. it is potential deadlock source vs. call_lock in smp_call_function() The only possible side effect of the removal might be, that an absolute CLOCK_REALTIME timer fires 1 second too late, in the rare case of leap second deletion and an absolute CLOCK_REALTIME timer which expires in the affected time frame. It will never fire too early. This was probably observed by the reporter of a June 30th -> July 1st hang: http://lkml.org/lkml/2007/7/3/103 A similar problem was observed by Dave Jones, who provided a screen shot with a lockdep back trace, which allowed to analyse the problem.

2007-07-03V4L/DVB (5818): CinergyT2: fix flush_workqueue() vs work->func() deadlockOleg Nesterov
Spotted and tested by Thomas Sattler <tsattler@gmx.de>. cinergyT2.c does cancel_delayed_work() + flush_scheduled_work() while holding cinergyt2->sem. This leads to deadlock because work->func() needs the same mutex to complete. Another bug is that this code in fact can't reliably stop the re-arming delayed_work. Convert this code to use cancel_rearming_delayed_work() and move it out of ->sem. Another mutex, ->wq_sem, was added to protect against the concurrent open/resume. This patch is a horrible hack to fix the lockup which happens in practice. As Dmitry Torokhov pointed out this driver has other problems and needs further changes.

2007-07-03V4L/DVB (5816): Cx88-blackbird: fix vidioc_g_tuner never ending list of tunersJelle Foks
v4l-info and other programs would loop indefinitely while querying the tuners for cx88-blackbird cards. The cause was that vidioc_g_tuner didn't return an error value for qctrl->id != 0, making the application think there is a never ending list of tuners... This patch adds the same index check as done in vidioc_g_tuner() in cx88-video.

2007-07-03V4L/DVB (5808): Bttv: fix v4l1 breaking the driverTrent Piepho
If one uses a V4L *one* application, such as vlc or mplayer's v4l driver, as the first user after the driver is loaded, the driver wedges itself and will never capture properly. Even if one uses a V4L2 application later, it still won't work. If one uses a V4L *two* application first, such as tvtime or mplayer's v4l2 driver, then the driver will be ok. One can then run a V4L1 application, and it will work. It turns out the problem is with norm changing and the crop support that was added in 2.6.21. The driver defaults to PAL, and keeps the last norm it was set too across opens. If one changes the norm via V4L1, the cropping parameters are not reset like they should be, and they'll remain broken across device opens. This patch removes the direct setting of btv->tvnorm in the V4L1 ioctl VIDIOCSCHAN handler. The norm is set via the existing call to set_input(), which calls set_tvnorm(), which will reset the cropping values now that it is able to detect the norm change.

The PCI-ID 1183 is SATA in PATA-emulation, but not fully compatible to SiS5513/5518. sata_sis.c is forwarding this ID to pata_sis. 1183 is not working if simply added to pata_sis.

Recently the PLL input clock of pata_pdc2027x is sometimes detected higer than expected (e.g. 20.027 MHz compared to 16.714 MHz). It seems sometimes the mdelay() function is not as precise as it used to be. Per Alan's advice, HT or power management might affect the precision of mdelay(). This patch calls gettimeofday() to mesure the time elapsed and calculate the PLL input clock accordingly.

2007-07-01PM: introduce set_target method in pm_opsRafael J. Wysocki
Commit 52ade9b3b97fd3bea42842a056fe0786c28d0555 changed the suspend code ordering to execute pm_ops->prepare() after the device model per-device .suspend() calls in order to fix some ACPI-related issues. Unfortunately, it broke the at91 platform which assumed that pm_ops->prepare() would be called before suspending devices. at91 used pm_ops->prepare() to get notified of the target system sleep state, so that it could use this information while suspending devices. However, with the current suspend code ordering pm_ops->prepare() is called too late for this purpose. Thus, at91 needs an additional method in 'struct pm_ops' that will be used for notifying the platform of the target system sleep state. Moreover, in the future such a method will also be needed by ACPI. This patch adds the .set_target() method to 'struct pm_ops' and makes the suspend code call it, if implemented, before executing the device model per-device .suspend() calls. It also modifies the at91 code to use pm_ops->set_target() instead of pm_ops->prepare(). Signed-off-by: Rafael J.
