Most architectures scan the all the same items early in the FDT and none are really architecture specific. Create a common early_init_dt_scan to unify the early scan of root, memory, and chosen nodes in the flattened DT.

Several architectures using DT support built-in dtb's in the init section. These platforms need to copy the dtb from init since the strings are referenced after unflattening. Every arch has their own copying routine which do the same thing. Create a common function, unflatten_and_copy_device_tree, to copy the dtb when unflattening the dtb.

So lets revert it and re-try the patch in v3.13.

Pull ACPI and power management fixes from Rafael Wysocki: "These fix one recent cpufreq regression, a few older bugs that may harm users and a kerneldoc typo. Specifics: 1) After the recent locking changes in the cpufreq core it is possible to trigger BUG_ON(!policy) in lock_policy_rwsem_read() if cpufreq_get() is called before registering a cpufreq driver. Fix from Viresh Kumar. 2) If intel_pstate has been loaded already, it doesn't make sense to do anything in acpi_cpufreq_init() and moreover doing something in there in that case may be harmful, so make that function return immediately if another cpufreq driver is already present. From Yinghai Lu. 3) The ACPI IPMI driver sometimes attempts to acquire a mutex from interrupt context, which can be avoided by replacing that mutex with a spinlock. From Lv Zheng. 4) A NULL pointer may be dereferenced by the exynos5440 cpufreq driver if a memory allocation made by it fails. Fix from Sachin Kamat. 5) Hanjun Guo's commit fixes a typo in the kerneldoc comment documenting acpi_bus_unregister_driver()" * tag 'pm+acpi-3.12-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI / scan: fix typo in comments of acpi_bus_unregister_driver() cpufreq: exynos5440: Fix potential NULL pointer dereference cpufreq: check cpufreq driver is valid and cpufreq isn't disabled in cpufreq_get() acpi-cpufreq: skip loading acpi_cpufreq after intel_pstate ACPI / IPMI: Fix atomic context requirement of ipmi_msg_handler()

Yinghai Lu authored
Ben Herrenschmidt found that commit 928bea96 ("PCI: Delay enabling bridges until they're needed") breaks PCI in some powerpc environments. The reason is that the PCIe port driver will call pci_enable_device() on the bridge, so the device is enabled, but skips pci_set_master because pcie_port_auto and no acpi on powerpc. Because of that, pci_enable_bridge() later on (called as a result of the child device driver doing pci_enable_device) will see the bridge as already enabled and will not call pci_set_master() on it. Fixed by add checking in pci_enable_bridge, and call pci_set_master if driver skip that. That will make the code more robot and wade off problem for missing pci_set_master in drivers.

Pull s390 lockref enablement from Heiko Carstens: "Enabling the new lockless lockref variant on s390 would have been trivial until Tony Luck added a cpu_relax() call into the CMPXCHG_LOOP(), with commit d472d9d9 ("lockref: Relax in cmpxchg loop") As already mentioned cpu_relax() is very expensive on s390 since it yields() the current virtual cpu. So we are talking of several thousand cycles. Considering this enabling the lockless lockref variant would contradict the intention of the new semantics. And also some quick measurements show performance regressions of 50% and more. Simply removing the cpu_relax() call again seems also not very desireable since Waiman Long reported that for some workloads the call improved performance by 5%." * 'lockref' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: s390: enable ARCH_USE_CMPXCHG_LOCKREF lockref: use arch_mutex_cpu_relax() in CMPXCHG_LOOP() mutex: replace CONFIG_HAVE_ARCH_MUTEX_CPU_RELAX with simple ifdef
