Subject[PATCH 4/5] openrisc: Use the new GENERIC_IRQ_MULTI_HANDLER
Date
From
It appears that openrisc copied arm64's GENERIC_IRQ_MULTI_HANDLER code
(which came from arm). I wanted to make this generic so I could use it
in the RISC-V port. This patch converts the openrisc code to use the
generic version.
