Subject: [PATCH 19/19] arm64: kdump: relax BUG_ON() if more than one cpus are still active
Date: Fri, 15 Jan 2016 19:18:38 +0000 [thread overview]
Message-ID: <e52b39c76d2a967bdecc376daee07d6edd47b01a.1452884156.git.geoff@infradead.org> (raw)
In-Reply-To: <cover.1452884156.git.geoff@infradead.org>
From: AKASHI Takahiro <takahiro.akashi@linaro.org>
We should try best in case of kdump.
So even if not all secondary cpus have shut down, we do kdump anyway.
