Subject: [PATCH 2/6] powerpc/mm: Avoid double irq save/restore in activate_mm
Date: Mon, 24 Jul 2017 14:27:59 +1000 [thread overview]
Message-ID: <20170724042803.25848-2-benh@kernel.crashing.org> (raw)
In-Reply-To: <20170724042803.25848-1-benh@kernel.crashing.org>
It calls switch_mm() which already does the irq save/restore
these days.
