A new sysfs shost attribute called "BMR_status" is implemented to report Backup Rail Monitor status. This attribute is located in the path /sys/class/scsi_host/host#/BMR_status when reading this adapter attribute, then driver will output the state of GPIO[24]. It returns "0" if BMR is healthy and it returns "1" for failure. if it returns an empty string then it means that there was an error while obtaining the BMR status.

Provide a "simple-dev-pm-ops" implementation that shuts down the domain and the device on suspend, and resumes the device and the domain on resume. All of the mechanics of restoring domain connectivity are handled by libsas once isci has notified libsas that all links should be back up. libsas is in charge of handling links that did not resume, or resumed out of order.

libsas power management routines to suspend and recover the sas domain based on a model where the lldd is allowed and expected to be "forgetful". sas_suspend_ha - disable event processing allowing the lldd to take down links without concern for causing hotplug events. Regardless of whether the lldd actually posts link down messages libsas notifies the lldd that all domain_devices are gone. sas_prep_resume_ha - on the way back up before the lldd starts link training clean out any spurious events that were generated on the way down, and re-enable event processing sas_resume_ha - after the lldd has started and decided that all phys have posted link-up events this routine is called to let libsas start it's own timeout of any phys that did not resume. After the timeout an lldd can cancel the phy teardown by posting a link-up event. Storage for ex_change_count (u16) and phy_change_count (u8) are changed to int so they can be set to -1 to indicate 'invalidated'.

Reuse ata_port_{suspend|resume}_common for sas. This path is chosen over adding coordination between ata-tranport and sas-transport because libsas wants to revalidate the domain at resume-time at the host level. It can not validate links have resumed properly until libata has had a chance to perform its revalidation, and any sane placing of an ata_port in the sas-transport model would delay it's resumption until after the host. Export the common portion of port suspend/resume (bypass pm_runtime), and allow sas to perform these operations asynchronously (similar to the libsas async-ata probe implmentation). Async operation is determined by having an external, rather than stack based, location for storing the result of the operation.

Following a report of a crash during an automount expire I found that the locking in fs/autofs4/expire.c:get_next_positive_subdir() was wrong. Not only is the locking wrong but the function is more complex than it needs to be. The function is meant to calculate (and dget) the next entry in the list of directories contained in the root of an autofs mount point (an autofs indirect mount to be precise). The main problem was that the d_lock of the owner of the list was not being taken when walking the list, which lead to list corruption under load. The only other lock that needs to be taken is against the next dentry candidate so it can be checked for usability.

On a 2-node machine with 256GB of ram we get 512 lines of console output, which is just too much. This mimicks Yinghai Lu's x86 commit c2b91e2e (x86_64/mm: check and print vmemmap allocation continuous) except that we aren't ever going to get contiguous block pointers in between calls so just print when the virtual address or node changes.

eDP is tons of fun. It turns out that at least the new MacBook Air 5,1 model absolutely doesn't like the new force vdd dance we've introduced in commit 6cb49835 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Sun May 20 17:14:50 2012 +0200 drm/i915: enable vdd when switching off the eDP panel But that patch also tried to fix some neat edp sequence issue with the force_vdd timings. Closer inspection reveals that we've raised force_vdd only to do the aux channel communication dp_sink_dpms. If we move the edp_panel_off below that, we don't need any force_vdd for the disable sequence, which makes the Air happy. Unfortunately the reporter of the original bug that the above commit fixed is travelling, so we can't test whether this regresses things. But my theory is that since we don't check for any power-off -> force_vdd-on delays in edp_panel_vdd_on, this was the actual root-cause of this failure. With that force_vdd dance completely eliminated, I'm hopeful the original bug stays fixed, too. For reference the old bug, which hopefully doesn't get broken by this: https://bugzilla.kernel.org/show_bug.cgi?id=43163 In any case, regression fixers win over plain bugfixes, so this needs to go in asap. v2: The crucial pieces seems to be to clear the force_vdd flag uncoditionally, too, in edp_panel_off. Looks like this is left behind by the firmware somehow. v3: The Apple firmware seems to switch off the panel on it's own, hence we still need to keep force_vdd on, but properly clear it when switching the panel off.
