Linus Torvalds a087241716 - Always initialize kernel stack backchain when entering the kernel, so 
that unwinding works properly.
 
 - Fix stack  unwinder test case to avoid rare interrupt stack corruption.
 
 - Simplify udelay() and just let it busy loop instead of implementing a
   complex logic.
 
 - arch_cpu_idle() cleanup.
 
 - Some other minor improvements.

 "This is mainly to decouple udelay() and arch_cpu_idle() and simplify
  both of them.

  Summary:

   - Always initialize kernel stack backchain when entering the kernel,
     so that unwinding works properly.

   - Fix stack unwinder test case to avoid rare interrupt stack
     corruption.

   - Simplify udelay() and just let it busy loop instead of implementing
     a complex logic.

   - arch_cpu_idle() cleanup.

   - Some other minor improvements"
