Merge branch 'timers-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip
* 'timers-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip: timers: fix build error in !oneshot case x86: c1e_idle: don't mark TSC unstable if CPU has invariant TSC x86: prevent C-states hang on AMD C1E enabled machines clockevents: prevent mode mismatch on cpu online clockevents: check broadcast device not tick device clockevents: prevent stale tick_next_period for onlining CPUs x86: prevent stale state of c1e_mask across CPU offline/online clockevents: prevent cpu online to interfere with nohz
