alpha: simplify fork and friends

2012-11-29T02:49:03Z

* no need to restore everything from switch_stack when we only need $26 * no need to pass current_pt_regs() manually, we can just as easily calculate it in alpha_clone/alpha_vfork ($8 + constant) * interpretation of zero usp as "use the parent's" is simpler in copy_thread(); let fork and vfork just pass 0.

alpha: Add missing RCU idle APIs on idle loop

2012-09-23T14:44:43Z

In the old times, the whole idle task was considered as an RCU quiescent state. But as RCU became more and more successful overtime, some RCU read side critical section have been added even in the code of some architectures idle tasks, for tracing for example. So nowadays, rcu_idle_enter() and rcu_idle_exit() must be called by the architecture to tell RCU about the part in the idle loop that doesn't make use of rcu read side critical sections, typically the part that puts the CPU in low power mode. This is necessary for RCU to find the quiescent states in idle in order to complete grace periods. Add this missing pair of calls in the Alpha's idle loop. Reported-by: Paul E.
