Pull pile 2 of execve and kernel_thread unification work from Al Viro:
 "Stuff in there: kernel_thread/kernel_execve/sys_execve conversions for
  several more architectures plus assorted signal fixes and cleanups.

  There'll be more (in particular, real fixes for the alpha
  do_notify_resume() irq mess)..."

mn10300: Add missing RCU idle APIs on idle loop

2012-09-23T14:44:48+00:00

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 mn10300's idle loop.

mn10300: fix "pull clearing RESTORE_SIGMASK into block_sigmask()" fallout

2012-07-17T23:21:29+00:00

Commit a610d6e672d6 ("pull clearing RESTORE_SIGMASK into
block_sigmask()") caused:

  arch/mn10300/kernel/signal.c: In function 'handle_signal':
  arch/mn10300/kernel/signal.c:462:3: warning: 'return' with no value, in function returning non-void [-Wreturn-type]

Add the missing return values, and restore the indentation while we're
at it.
