| * | alpha: Change do_timer() to xtime_update()Torben Hohn2011-01-311-6/+2
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | xtime_update() takes the xtime_lock itself. timer_interrupt() is only called on the boot cpu. See do_entInt(). So "state" in timer_interrupt does not require protection by xtime_lock.

This was confusing at best, and could be a source of livelocks in places that retry the cmpxchg_futex_value_locked after trying to fix the issue by running fault_in_user_writeable(). This change makes the cmpxchg_futex_value_locked API more similar to the get_futex_value_locked one, returning an error code and updating the original value through a reference argument.

| | | | | | | | | | | | | | Commit df9ee29270 made arch_local_irq_save and arch_local_irq_restore static inline which with -Werror trips up on __set_hae() and _set_hae() which are extern inline. The naive solution is to make __set_hae() and set_hae() static inline but for reasons described in commit d559d4a24a3fe this breaks the generic kernel build. Instead, since this is architecture specific code, this patch hard wires in the architecture specific method f disabling and enabling interrupts.

* | perf: Dynamic pmu typesPeter Zijlstra2010-12-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Extend the perf_pmu_register() interface to allow for named and dynamic pmu types. Because we need to support the existing static types we cannot use dynamic types for everything, hence provide a type argument. If we want to enumerate the PMUs they need a name, provide one.

* | perf, arch: Cleanup perf-pmu init vs lockup-detectorPeter Zijlstra2010-11-263-11/+6
|/ | | | | | | | | | | | | | | | | | | | | | The perf hardware pmu got initialized at various points in the boot, some before early_initcall() some after (notably arch_initcall). The problem is that the NMI lockup detector is ran from early_initcall() and expects the hardware pmu to be present. Sanitize this by moving all architecture hardware pmu implementations to initialize at early_initcall() and move the lockup detector to an explicit initcall right after that.
