ARM: davinci: da850: fix infinite loop in clk_set_rate()
The aemif clock is added twice to the lookup table in da850.c. This breaks the children list of pll0_sysclk3 as we're using the same list links in struct clk. When calling clk_set_rate(), we get stuck in propagate_rate(). Create a separate clock for nand, inheriting the rate of the aemif clock and retrieve it in the davinci_nand module.

perf/x86/intel/rapl: Make package handling more robust
The package management code in RAPL relies on package mapping being available before a CPU is started. This changed with: 9d85eb9119f4 ("x86/smpboot: Make logical package management more robust") because the ACPI/BIOS information turned out to be unreliable, but that left RAPL in broken state. This was not noticed because on a regular boot all CPUs are online before RAPL is initialized. A possible fix would be to reintroduce the mess which allocates a package data structure in CPU prepare and when it turns out to already exist in starting throw it away later in the CPU online callback. But that's a horrible hack and not required at all because RAPL becomes functional for perf only in the CPU online callback. That's correct because user space is not yet informed about the CPU being onlined, so nothing caan rely on RAPL being available on that particular CPU. Move the allocation to the CPU online callback and simplify the hotplug handling. At this point the package mapping is established and correct. This also adds a missing check for available package data in the event_init() function.
