Date: Tue, 30 Aug 2022 13:28:19 +0900 From: Yun Levi <ppbuk5246@...il.com> To: will@...nel.org, chenzhou10@...wei.com, nramas@...ux.microsoft.com, thunder.leizhen@...wei.com Cc: linux-arm-kernel@...ts.infradead.org, Linux Kernel Mailing List <linux-kernel@...r.kernel.org>, kexec@...ts.infradead.org Subject: [PATCH-RESEND] arm64/kexec: Fix missing extra range for crashkres_low. 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.
