linux-next: build warnings after merge of the acpi tree

[PATCH 5/8] sched: clarify commment for TS_POLLING
From: Len Brown <len.brown(a)intel.com> TS_POLLING set tells the scheduler a task will poll need_resched() to look for work. TS_POLLING clear tells resched_task() and wake_up_idle_cpu() that the remote CPU is sleeping in idle, and thus requires a reschedule interrupt to wake them to notice work. Update the de... 26 May 2010 23:32
