Subject: [PATCH] arm64/kexec: Fix missing extra range for crashkres_low.
Date: Thu,  4 Aug 2022 00:12:17 +0900	[thread overview]
Message-ID: <20220803151217.75962-1-ppbuk5246@gmail.com> (raw)

Like crashk_res, Calling crash_exclude_mem_range function with
crashk_low_res area would need extra crash_mem range too.
Add one extra crash_mem range when crashk_low_res is used.
