Subject: [PATCH v4] openrisc: Use the new GENERIC_IRQ_MULTI_HANDLER
Date: Mon, 12 Mar 2018 11:44:29 -0700 [thread overview]
Message-ID: <20180312184429.20515-1-palmer@sifive.com> (raw)
In-Reply-To: <20180307235731.22627-6-palmer@sifive.com>
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.
