2013-08-09drm: provide agp dummies for CONFIG_AGP=nDavid Herrmann
We currently rely on gcc dead-code elimination so the drm_agp_* helpers are not called if drm_core_has_AGP() is false. That's ugly as hell so provide "static inline" dummies for the case that AGP is disabled.

2013-08-07SUNRPC: If the rpcbind channel is disconnected, fail the call to unregisterTrond Myklebust
If rpcbind causes our connection to the AF_LOCAL socket to close after we've registered a service, then we want to be careful about reconnecting since the mount namespace may have changed. By simply refusing to reconnect the AF_LOCAL socket in the case of unregister, we avoid the need to somehow save the mount namespace. While this may lead to some services not unregistering properly, it should be safe.

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.

2013-08-07perf: Add PERF_EVENT_IOC_ID ioctl to return event IDJiri Olsa

While this is ok for current read format used by perf tool, it is not ok when we use PERF_FORMAT_GROUP format.

2013-08-07drm/mm: remove unused APIDavid Herrmann
We used to pre-allocate drm_mm nodes and save them in a linked list for later usage so we always have spare ones in atomic contexts. However, this is really racy if multiple threads are in an atomic context at the same time and we don't have enough spare nodes. Moreover, all remaining users run in user-context and just lock drm_mm with a spinlock. So we can easily preallocate the node, take the spinlock and insert the node. This may have worked well with BKL in place, however, with today's infrastructure it really doesn't make any sense. Besides, most users can easily embed drm_mm_node into their objects so no allocation is needed at all. Thus, remove the old pre-alloc API and all the helpers that it provides. Drivers have already been converted and we should not use the old API for new code, anymore.

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.

Move acpi_bus_get_device() from bus.c to scan.c which allows acpi_bus_data_handler() to become static and clean up the latter. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

A few places in the code (mac80211 and iwlmvm) use the same TU_TO_JIFFIES() macro and could use TU_TO_EXP_TIME() that mac80211 has. Make these available to everyone and use them. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

The nand driver use cpu_is_at32ap7000() macro for a workaround. For the multi-platform support, we will remove this cpu_is_xxx() macro. This patch adds a boolean variable need_reset_workaround in structure atmel_nand_data. Using this variable we can remove cpu_is_at32ap7000() macro.

2013-08-05mtd: nand: reword nand_chip bad block interface commentsBrian Norris
This remedies a few problems: (1) The use of "the" vs. "a" is a little confusing, IMO. (2) nand_chip.block_bad is used exclusively for checking the OOB bad block markers of a NAND. Any BBT functionality is handled in nand_bbt.c, so this description should differentiate itself from nand_bbt.c.
