Subject: [RFC PATCH 17/27] powerpc/64s/exception: re-inline some handlers
Date: Sun, 15 Sep 2019 11:28:03 +1000	[thread overview]
Message-ID: <20190915012813.29317-18-npiggin@gmail.com> (raw)
In-Reply-To: <20190915012813.29317-1-npiggin@gmail.com>

The reduction in interrupt entry size allows some handlers to be
re-inlined.
