Stephen Rothwell 88f0178e6e [POWERPC] iSeries: don't printk with HV spinlock held 
Printk was observed to hang during module unload due to a limited
window of characters that may be sent to the hypervisor.  The window
only reexpands when we receive an ack from the HV and the spinlock here
prevents us from ever processing that ack.  This fixes it by dropping
the lock before doing the printk, then looping back to the top to
reacquire the lock.
