Subject: [PATCH v4 6/8] arm64: Use the new GENERIC_IRQ_MULTI_HANDLER
Date: Tue, 27 Mar 2018 09:19:09 -0700	[thread overview]
Message-ID: <20180327161911.14086-7-palmer@sifive.com> (raw)
In-Reply-To: <20180327161911.14086-1-palmer@sifive.com>

It appears arm64 copied arm's GENERIC_IRQ_MULTI_HANDLER code, but made
it unconditional.  I wanted to make this generic so it could be used by
the RISC-V port.  This patch converts the arm64 code to use the new
generic code, which simply consists of deleting the arm64 code and
setting MULTI_IRQ_HANDLER instead.
