Subject: [RFC PATCH 4/5] RISC-V: Move interrupt cause declarations to irq.h
Date: Wed, 15 Aug 2018 16:56:16 -0700	[thread overview]
Message-ID: <1534377377-70108-5-git-send-email-atish.patra@wdc.com> (raw)
In-Reply-To: <1534377377-70108-1-git-send-email-atish.patra@wdc.com>

CPU hotplug code in smpboot requires interrupt cause
to identify the cause of cpu wakeup.

Move the IRQ cause declarations to appropriate header
file.
