2009-01-27SATA: Blacklisting of systems that spin off disks during ACPI power offRafael J. Wysocki
Introduce new libata flags ATA_FLAG_NO_POWEROFF_SPINDOWN and ATA_FLAG_NO_HIBERNATE_SPINDOWN that, if set, will prevent disks from being spun off during system power off and hibernation, respectively (to handle the hibernation case we need the new system state SYSTEM_HIBERNATE_ENTER that can be checked against by libata, in analogy with SYSTEM_POWER_OFF).

2009-01-27DMI: Introduce dmi_first_match to make the interface more flexibleRafael J. Wysocki
Some notebooks from HP have the problem that their BIOSes attempt to spin down hard drives before entering ACPI system states S4 and S5. This leads to a yo-yo effect during system power-off shutdown and the last phase of hibernation when the disk is first spun down by the kernel and then almost immediately turned on and off by the BIOS. This, in turn, may result in shortening the disk's life times. To prevent this from happening we can blacklist the affected systems using DMI information. However, only the on-board controlles should be blacklisted and their PCI slot numbers can be used for this purpose. Unfortunately the existing interface for checking DMI information of the system is not very convenient for this purpose, because to use it, we would have to define special callback functions or create a separate struct dmi_system_id table for each blacklisted system. To overcome this difficulty introduce a new function dmi_first_match() returning a pointer to the first entry in an array of struct dmi_system_id elements that matches the system DMI information. Then, we can use this pointer to access the entry's .driver_data field containing the additional information, such as the PCI slot number, allowing us to do the desired blacklisting.

2009-01-27Hibernation: Introduce system_entering_hibernationRafael J. Wysocki
Introduce boolean function system_entering_hibernation() returning 'true' during the last phase of hibernation, in which devices are being put into low power states and the sleep state (for example, ACPI S4) is finally entered. Some device drivers need such a function to check if the system is in the final phase of hibernation. In particular, some SATA drivers are going to use it for blacklisting systems in which the disks should not be spun down during the last phase of hibernation (the BIOS will do that anyway).

2009-01-16PCI PM: Restore standard config registers of all devices earlyRafael J. Wysocki
There is a problem in our handling of suspend-resume of PCI devices that many of them have their standard config registers restored with interrupts enabled and they are put into the full power state with interrupts enabled as well. This may lead to the following scenario: * an interrupt vector is shared between two or more devices * one device is resumed earlier and generates an interrupt * the interrupt handler of another device tries to handle it and attempts to access the device the config space of which hasn't been restored yet and/or which still is in a low power state * the system crashes as a result To prevent this from happening we should restore the standard configuration registers of all devices with interrupts disabled and we should put them into the D0 power state right after that. Unfortunately, this cannot be done using the existing pci_set_power_state(), because it can sleep. Also, to do it we have to make sure that the config spaces of all devices were actually saved during suspend. Signed-off-by: Rafael J.

2009-01-16quota: Improve lockingJan Kara
We implement dqget() and dqput() that need neither dqonoff_mutex nor dqptr_sem. Then move dqget() and dqput() calls so that they are not called from under dqptr_sem. This is important because filesystem callbacks aren't called from under dqptr_sem which used to cause *lots* of problems with lock ranking (and with OCFS2 they became close to unsolvable). The patch also removes two functions which were introduced solely because OCFS2 needed them to cope with the old locking scheme. As time showed, they were not enough for OCFS2 anyway and it would be unnecessary work to adapt them to the new locking scheme in which they aren't needed. As a result OCFS2 needs the following patch to compile properly with quotas. Sorry to any bisecters which hit this in advance. Signed-off-by: Jan Kara <jack@suse.cz>
