This was actually resolving the problem on the VAIO\nbut was just a stupid workaround, which was not tackling the root\ncause: the assignement of lower idle C-States in the ACPI processor_idle\ncode. The cpuidle patches, which utilize the dynamic tick feature and\ngo faster into deeper C-states exposed the problem again. The correct\nsolution is the previous patch, which prevents lower C-states across\nthe suspend/resume.\n\nRemove the enforcement code, including the conditional broadcast timer\narming, which helped to pamper over the real problem for quite a time.\nThe oneshot broadcast flag for the cpu, which runs the resume code can\nnever be set at the time when this code is executed. It only gets set,\nwhen the CPU is entering a lower idle C-State.\n\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nTested-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nCc: Len Brown \u003clenb@kernel.org\u003e\nCc: Venkatesh Pallipadi \u003cvenkatesh.pallipadi@intel.com\u003e\nCc: Rafael J.
