Pull device tree updates from Grant Likely: "The branch contains the following device tree changes the v3.17 merge window: Group changes to the device tree. In preparation for adding device tree overlay support, OF_DYNAMIC is reworked so that a set of device tree changes can be prepared and applied to the tree all at once. OF_RECONFIG notifiers see the most significant change here so that users always get a consistent view of the tree. Notifiers generation is moved from before a change to after it, and notifiers for a group of changes are emitted after the entire block of changes have been applied Automatic console selection from DT. Console drivers can now use of_console_check() to see if the device node is specified as a console device. If so then it gets added as a preferred console. UART devices get this support automatically when uart_add_one_port() is called. DT unit tests no longer depend on pre-loaded data in the device tree. Data is loaded dynamically at the start of unit tests, and then unloaded again when the tests have completed. Also contains a few bugfixes for reserved regions and early memory setup" * tag 'devicetree-for-linus' of git://git.secretlab.ca/git/linux: (21 commits) of: Fixing OF Selftest build error drivers: of: add automated assignment of reserved regions to client devices of: Use proper types for checking memory overflow of: typo fix in __of_prop_dup() Adding selftest testdata dynamically into live tree of: Add todo tasklist for Devicetree of: Transactional DT support. of: Reorder device tree changes and notifiers of: Move dynamic node fixups out of powerpc and into common code of: Make sure attached nodes don't carry along extra children of: Make devicetree sysfs update functions consistent. of: Create unlocked versions of node and property add/remove functions OF: Utility helper functions for dynamic nodes of: Move CONFIG_OF_DYNAMIC code into a separate file of: rename of_aliases_mutex to just of_mutex of/platform: Fix of_platform_device_destroy iteration of devices of: Migrate of_find_node_by_name() users to for_each_node_by_name() tty: Update hypervisor tty drivers to use core stdout parsing code. arm/versatile: Add the uart as the stdout device. of: Enable console on serial ports specified by /chosen/stdout-path ...

When a MC is handled, the correct sbridge_dev is searched based on the node, checking again later with the assumption the first memory controller found is the first socket's memory controller is a bogus assumption.

2014-06-26sb_edac: make minimal use of channel_maskAristeu Rozanski1-0/+3
channel_mask will be used in the future to determine which group of memory modules is causing the errors since when mirroring, lockstep and close page are enabled you can't.

There are a bunch of users open coding the for_each_node_by_name() by calling of_find_node_by_name() directly instead of using the macro.

2014-02-25i7300_edac: Fix device reference countJean Delvare1-18/+20
pci_get_device() decrements the reference count of "from" (last argument) so when we break off the loop successfully we have only one device reference - and we don't know which device we have. If we want a reference to each device, we must take them explicitly and let the pci_get_device() walk complete to avoid duplicate references. This is serious, as over-putting device references will cause the device to eventually disappear. Without this fix, the kernel crashes after a few insmod/rmmod cycles. Tested on an Intel S7000FC4UR system with a 7300 chipset.

2014-02-25i7core_edac: Fix PCI device reference countJean Delvare1-2/+7
The reference count changes done by pci_get_device can be a little misleading when the usage diverges from the most common scheme. The reference count of the device passed as the last parameter is always decreased, even if the function returns no new device. So if we are going to try alternative device IDs, we must manually increment the device reference count before each retry. If we don't, we end up decreasing the reference count, and after a few modprobe/rmmod cycles the PCI devices will vanish. In other words and as Alan put it: without this fix the EDAC code corrupts the PCI device list.

2014-02-24MCE, AMD: Fix decoding module loading on unsupported hwBorislav Petkov1-32/+33
We want to still be able to issue some error information on systems for which there is no decoding support (think older distro kernels here, for example). Therefore, we allow module registration but skip the per-family bank-specific decoders and issue the general information only, i.e.: [ 46.822828] [Hardware Error]: Error Status: Uncorrected, software containable error. [ 46.822846] [Hardware Error]: CPU:0 (15:30:0) MC0_STATUS[-|UE|-|-|-|-|-]: 0xa000000000010f0f [ 46.822858] [Hardware Error]: cache level: L3/GEN, mem/io: GEN, mem-tx: GEN, part-proc: GEN (timed out) with the hope that it still contains helpful useful bits.

We're using edac_mc_workq_setup() both on the init path, when we load an edac driver and when we change the polling period (edac_mc_reset_delay_period) through /sys/.../edac_mc_poll_msec.
