#     powerpc/xive: Fix trying to "push" an already active pool VP
#     
#     When setting up a CPU, we "push" (activate) a pool VP for it.
#     
#     However it's an error to do so if it already has an active
#     pool VP.
#     
#     This happens when doing soft CPU hotplug on powernv since we
#     don't tear down the CPU on unplug. The HW flags the error which
#     gets captured by the diagnostics.
#     
#     Fix this by making sure to "pull" out any already active pool
#     first.
#
