sparc32: Call sun4m_clear_profile_irq() directly from sun4m_smp.c
This is the only use of the clear_profile_irq() btfixup entry, which just eats up lots of dead space on other platform types. A subsequent commit will delete the other implementations and the btfixup entry as well. Signed-off-by: David S. Miller <davem@davemloft.net>
