sgi-xp: nested calls to spin_lock_irqsave()

2012-07-11T23:04:47Z

The code here has a nested spin_lock_irqsave(). It's not needed since IRQs are already disabled and it causes a problem because it means that IRQs won't be enabled again at the end. The second call to spin_lock_irqsave() will overwrite the value of irq_flags and we can't restore the proper settings.

mei: pci_resume: set IRQF_ONESHOT for msi request_threaded_irq

2012-07-10T17:45:07Z

when the default irq quick handler is used then IRQF_ONESHOT must be set otherwise the request fails and following error is displayed: mei 0000:00:16.0: irq 48 for MSI/MSI-X genirq: Threaded irq requested with handler=NULL and !ONESHOT for irq 48 mei 0000:00:16.0: request_threaded_irq failed: irq = 48. dpm_run_callback(): pci_pm_resume+0x0/0x140 returns -22 PM: Device 0000:00:16.0 failed to resume async: error -22 Reported-by: Peter Wu Signed-off-by: Tomas Winkler Tested-by: Peter Wu Signed-off-by: Roland Dreier Cc: stable # 3.5 Signed-off-by: Greg Kroah-Hartman

misc: mei: set WDIOF_ALARMONLY on mei watchdog

2012-06-13T22:34:31Z

mei watchdog doesn't reboot the system it only produces event therefore mark it as WDIOF_ALARMONLY. This patch depends on: commit 2bbeed016dd96045ec82c3a309afddcc3a0db1d2 Author: Alan Cox watchdog: Add a flag to indicate the watchdog doesn't reboot things Signed-off-by: Tomas Winkler Signed-off-by: Greg Kroah-Hartman

misc: mei: Disable MSI when IRQ registration fails

2012-06-13T22:34:31Z

Since MSI is enabled right before that, we should disable it when registration fails. Signed-off-by: Samuel Ortiz Signed-off-by: Tomas Winkler Signed-off-by: Greg Kroah-Hartman

misc: mei: fix stalled read

2012-06-13T20:52:14Z

This bug caused severe connectivity issue in the LMS application (LMS is described in Documentation/misc-devices/mei/mei.txt) The bug was introduced in patch: commit 1ccb7b6249f9bc50678e2a383084ed0a34cc9239 staging/mei: propagate error codes up in the write flow The patch has reverted the return value logic of some fo function but the conditional in _mei_irq_thread_read function was not swapped making read always entering the error path Signed-off-by: Tomas Winkler Signed-off-by: Greg Kroah-Hartman

misc: mei: unregister misc device in pci_remove function

2012-06-13T20:52:14Z

Since the misc device is registered only in the pci probe function it has to be also unregistered in the counterpart pci remove function and not in the module exit function. In case of probe failure the driver was oopsing in module exit function. Signed-off-by: Tomas Winkler Signed-off-by: Greg Kroah-Hartman
