2013-09-06ACPICA: Fix for a Store->ArgX when ArgX contains a reference to a field.Bob Moore
This change fixes a problem where a Store operation to an ArgX object that contained a reference to a field object did not complete the automatic dereference and then write to the actual field object. Instead, the object type of the field object was inadvertently changed to match the type of the source operand. The new behavior will actually write to the field object (buffer field or field unit), thus matching the correct ACPI-defined behavior.

2013-09-06drm/i915: try not to lose backlight CBLV precisionJani Nikula
ACPI has _BCM and _BQC methods to set and query the backlight brightness, respectively. The ACPI opregion has variables BCLP and CBLV to hold the requested and current backlight brightness, respectively. The BCLP variable has range 0..255 while the others have range 0..100. This means the _BCM method has to scale the brightness for BCLP, and the gfx driver has to scale the requested value back for CBLV. If the _BQC method uses the CBLV variable (apparently some implementations do, some don't) for current backlight level reporting, there's room for rounding errors. Use DIV_ROUND_UP for scaling back to CBLV to get back to the same values that were passed to _BCM, presuming the _BCM simply uses bclp = (in * 255) / 100 for scaling to BCLP.

2013-09-05dm: add statistics supportMikulas Patocka
Support the collection of I/O statistics on user-defined regions of a DM device. If no regions are defined no statistics are collected so there isn't any performance impact. Only bio-based DM devices are currently supported. Each user-defined region specifies a starting sector, length and step. Individual statistics will be collected for each step-sized area within the range specified. The I/O statistics counters for each step-sized area of a region are in the same format as /sys/block/*/stat or /proc/diskstats but extra counters (12 and 13) are provided: total time spent reading and writing in milliseconds. All these counters may be accessed by sending the @stats_print message to the appropriate DM device via dmsetup. The creation of DM statistics will allocate memory via kmalloc or fallback to using vmalloc space. At most, 1/4 of the overall system memory may be allocated by DM statistics. The admin can see how much memory is used by reading /sys/module/dm_mod/parameters/stats_current_allocated_bytes See Documentation/device-mapper/statistics.txt for more details.

2013-09-05dm thin: always return -ENOSPC if no_free_space is setMike Snitzer
If pool has 'no_free_space' set it means a previous allocation already determined the pool has no free space (and failed that allocation with -ENOSPC). By always returning -ENOSPC if 'no_free_space' is set, we do not allow the pool to oscillate between allocating blocks and then not. But a side-effect of this determinism is that if a user wants to be able to allocate new blocks they'll need to reload the pool's table (to clear the 'no_free_space' flag). This reload will happen automatically if the pool's data volume is resized. But if the user takes action to free a lot of space by deleting snapshot volumes, etc the pool will no longer allow data allocations to continue without an intervening table reload.

2013-09-05dm ioctl: increase granularity of type_lock when loading tableMike Snitzer
Hold the mapped device's type_lock before calling populate_table() since it is where the table's type is determined based on the specified targets. There is no need to allow concurrent table loads to race to establish the table's targets or type. This eliminates the need to grab the lock in dm_table_set_type(). Also verify that the type_lock is held in both dm_set_md_type() and dm_get_md_type(). Signed-off-by: Mike Snitzer <snitzer@redhat.com> Signed-off-by: Alasdair G Kergon <agk@redhat.com>

2013-09-05dm: allow error target to replace bio-based and request-based targetsMike Snitzer
It may be useful to switch a request-based table to the "error" target. Enhance the DM core to allow a hybrid target_type which is capable of handling either bios (via .map) or requests (via .map_rq). Add a request-based map function (.map_rq) to the "error" target_type; making it DM's first hybrid target. Train dm_table_set_type() to prefer the mapped device's established type (request-based or bio-based). If the mapped device doesn't have an established type default to making the table with the hybrid target(s) bio-based. Tested 'dmsetup wipe_table' to work on both bio-based and request-based devices.

2013-09-05ACPI / hotplug / PCI: Don't trim devices before scanning the namespaceRafael J. Wysocki
In acpiphp_bus_add() we first remove device objects corresponding to the given handle and the ACPI namespace branch below it, which are then re-created by acpi_bus_scan(). This used to be done to clean up after surprise removals, but now we do the cleanup through trim_stale_devices() which checks if the devices in question are actually gone before removing them, so the device hierarchy trimming in acpiphp_bus_add() is not necessary any more and, moreover, it may lead to problems if it removes device objects corresponding to devices that are actually present. For this reason, remove the leftover acpiphp_bus_trim() from acpiphp_bus_add(). Reported-by: Alex Williamson <alex.williamson@redhat.com> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

Conflicts: drivers/net/ethernet/stmicro/stmmac/stmmac_platform.c net/bridge/br_multicast.c net/ipv6/sit.c The conflicts were minor: 1) sit.c changes overlap with change to ip_tunnel_xmit() signature. 2) br_multicast.c had an overlap between computing max_delay using msecs_to_jiffies and turning MLDV2_MRC() into an inline function with a name using lowercase instead of uppercase letters. 3) stmmac had two overlapping changes, one which conditionally allocated and hooked up a dma_cfg based upon the presence of the pbl OF property, and another one handling store-and-forward DMA made.
