Subject: [PATCH 1/7] Revert "riscv: Clear pending interrupts before enabling IPIs"
Date: Mon,  7 Sep 2020 14:16:53 -0400	[thread overview]
Message-ID: <20200907181659.92449-2-seanga2@gmail.com> (raw)
In-Reply-To: <20200907181659.92449-1-seanga2@gmail.com>

Clearing MIP doesn't do anything. Whoops. The following commits should
tackle this problem in a more robust manner.

This reverts commit 9472630337e7c4ac442066b5a752aaa8c3b4d4a6.
