------------------ From: Leo Yan <[email protected]> [ Upstream commit 831c326fcd0e8e2a6ece952f898a1ec9b1dc1004 ] Commit ad67b74d2469 ("printk: hash addresses printed with %p") lets printk specifier %p to hash all addresses before printing, this was resulting in the high 32 bits of pcsr can only output zeros. So module cannot completely print pc value and it's pointless for debugging purpose. This patch fixes this by using %px to print pcsr instead.
