    x86: Cache read of cpu_state in __cpu_die() for subsequent BUG_ON check.
    
    Otherwise compiler may re-read cpu_state for the BUG_ON and see a
    modified value causing erroneous BUG.

    sched_credit: Hold lock while dump scheduler info
    
    Dump runq with debug key 'r' may cause dead loop like below:
    
    (XEN) active vcpus:
    (XEN)     1: [1.0] pri=0 flags=0 cpu=0 credit=263 [w=256]
    (XEN)     2: [0.2] pri=0 flags=0 cpu=5 credit=284 [w=256]
    (XEN)     3: [0.2] pri=0 flags=0 cpu=5 credit=282 [w=256]
    ...
    (XEN)  xxxxx: [0.2] pri=0 flags=0 cpu=2 credit=54 [w=256]
    ...
    (XEN)  xxxxx: [0.2] pri=0 flags=0 cpu=3 credit=-48 [w=256]
    ...
    
    This means the active vcpu 0.2 became non-active with the active list
    element empty just after it was accessed in the loop '2:'.
    
    We should always hold a lock before access scheduler related list,
    even in the debug purpose dump code.

    x86: On CPU offline, fix master waiting for slave to be fully dead.
    
    On two back-to-back CPU offline operations, on second offline the
    cpu_state var will be CPU_STATE_DEAD from the first offline. Hence
    __cpu_die() will incorrectly not wait for the second slave to fully
    die and set cpu_state itself.
    
    The fix is to set cpu_state to a new value, CPU_STATE_DYING, earlier
    during CPU offline, before __cpu_die() starts to execute.
