2013-08-07ACPI: Try harder to resolve _ADR collisions for bridgesRafael J. Wysocki
In theory, under a given ACPI namespace node there should be only one child device object with _ADR whose value matches a given bus address exactly. In practice, however, there are systems in which multiple child device objects under a given parent have _ADR matching exactly the same address. In those cases we use _STA to determine which of the multiple matching devices is enabled, since some systems are known to indicate which ACPI device object to associate with the given physical (usually PCI) device this way. Unfortunately, as it turns out, there are systems in which many device objects under the same parent have _ADR matching exactly the same bus address and none of them has _STA, in which case they all should be regarded as enabled according to the spec. Still, if those device objects are supposed to represent bridges (e.g. this is the case for device objects corresponding to PCIe ports), we can try harder and skip the ones that have no child device objects in the ACPI namespace. With luck, we can avoid using device objects that we are not expected to use this way. Although this only works for bridges whose children also have ACPI namespace representation, it is sufficient to address graphics adapter detection issues on some systems, so rework the code finding a matching device ACPI handle for a given bus address to implement this idea. Introduce a new function, acpi_find_child(), taking three arguments: the ACPI handle of the device's parent, a bus address suitable for the device's bus type and a bool indicating if the device is a bridge and make it work as outlined above. Reimplement the function currently used for this purpose, acpi_get_child(), as a call to acpi_find_child() with the last argument set to 'false' and make the PCI subsystem use acpi_find_child() with the bridge information passed as the last argument to it. [Lan Tianyu notices that it is not sufficient to use pci_is_bridge() for that, because the device's subordinate pointer hasn't been set yet at this point, so use hdr_type instead.] This change fixes a regression introduced inadvertently by commit 33f767d (ACPI: Rework acpi_get_child() to be more efficient) which overlooked the fact that for acpi_walk_namespace() "post-order" means "after all children have been visited" rather than "on the way back", so for device objects without children and for namespace walks of depth 1, as in the acpi_get_child() case, the "post-order" callbacks ordering is actually the same as the ordering of "pre-order" ones. Since that commit changed the namespace walk in acpi_get_child() to terminate after finding the first matching object instead of going through all of them and returning the last one, it effectively changed the result returned by that function in some rare cases and that led to problems (the switch from a "pre-order" to a "post-order" callback was supposed to prevent that from happening, but it was ineffective). As it turns out, the systems where the change made by commit 33f767d actually matters are those where there are multiple ACPI device objects representing the same PCIe port (which effectively is a bridge). Moreover, only one of them, and the one we are expected to use, has child device objects in the ACPI namespace, so the regression can be addressed as described above.

2013-08-07ACPI / processor: move try_offline_node() after acpi_unmap_lsapic()Yasuaki Ishimatsu
try_offline_node() checks that all CPUs associated with the given node have been removed by using cpu_present_bits. If all cpus related to that node have been removed, try_offline_node() clears the node information. However, try_offline_node() called from acpi_processor_remove() never clears the node information. For disabling cpu_present_bits, acpi_unmap_lsapic() needs be called. Yet, acpi_unmap_lsapic() is called after try_offline_node() has run. So when try_offline_node() runs, the CPU's cpu_present_bits is always set. Fix the issue by moving try_offline_node() after acpi_unmap_lsapic(). The problem fixed here was uncovered by commit cecdb19 "ACPI / scan: Change the implementation of acpi_bus_trim()".

The SDVO code tries to compare the encoder's and crtc's idea of the pixel_multiplier. Normally they have to match, but when transitioning to DPMS off, we turn off the pipe before reading out the pipe_config, so the pixel_multiplier in the pipe_config will be 0, whereas the encoder will still have its pixel_multiplier set to whatever value we were using when the display was active.

2013-08-07drm/i915: fix gen4 digital port hotplug definitionsDaniel Vetter
Apparently Bspec is wrong in this case here even for gm45. Note that Bspec is horribly misguided on i965g/gm, so we don't have any other data points besides that it seems to make machines work better. With this changes all the bits in PORT_HOTPLUG_STAT for the digital ports are ordered the same way. This seems to agree with what register dumps from the hpd storm handling code shows, where the LIVE bit and the short/long pulse STATUS bits light up at the same time with this enumeration (but no with the one from Bspec). Also tested on my gm45 which has two DP+ ports, and everything seems to still work as expected.

2013-08-06ACPI: Drop physical_node_id_bitmap from struct acpi_deviceRafael J. Wysocki
The physical_node_id_bitmap in struct acpi_device is only used for looking up the first currently unused dependent phyiscal node ID by acpi_bind_one(). It is not really necessary, however, because acpi_bind_one() walks the entire physical_node_list of the given device object for sanity checking anyway and if that list is always sorted by node_id, it is straightforward to find the first gap between the currently used node IDs and use that number as the ID of the new list node. This also removes the artificial limit of the maximum number of dependent physical devices per ACPI device object, which now depends only on the capacity of unsigend int. As a result, it fixes a regression introduced by commit e2ff394 (ACPI / memhotplug: Bind removable memory blocks to ACPI device nodes) that caused acpi_memory_enable_device() to fail when the number of 128 MB blocks within one removable memory module was greater than 32.

The list of physical devices corresponding to an ACPI device object is walked by acpi_system_wakeup_device_seq_show() and physical_device_enable_wakeup() without taking that object's physical_node_lock mutex. Since each of those functions may be run at any time as a result of a user space action, the lack of appropriate locking in them may lead to a kernel crash if that happens during device hot-add or hot-remove involving the device object in question.

2013-08-05regmap: cache: Make sure to sync the last register in a blockLars-Peter Clausen
regcache_sync_block_raw_flush() expects the address of the register after last register that needs to be synced as its parameter. But the last call to regcache_sync_block_raw_flush() in regcache_sync_block_raw() passes the address of the last register in the block. This effectively always skips over the last register in a block, even if it needs to be synced. In order to fix it increase the address by one register.

2013-08-04ACPI / video: improve quirk check in acpi_video_bqc_quirk()Felipe Contreras
If the _BCL package ordering is descending, the first level (br->levels[2]) is likely to be 0, and if the number of levels matches the number of steps, we might confuse a returned level to mean the index. For example: current_level = max_level = 100 test_level = 0 returned level = 100 In this case 100 means the level, not the index, and _BCM failed. Still, if the _BCL package ordering is descending, the index of level 0 is also 100, so we assume _BQC is indexed, when it's not. This causes all _BQC calls to return bogus values causing weird behavior from the user's perspective. For example: xbacklight -set 10; xbacklight -set 20; would flash to 90% and then slowly down to the desired level (20). The solution is simple; test anything other than the first level (e.g. 1).
