From mboxrd@z Thu Jan 1 00:00:00 1970 From: ard.biesheuvel@linaro.org (Ard Biesheuvel) Date: Wed, 14 Jun 2017 12:43:55 +0200 Subject: [PATCH v2 2/2] arm64: mm: select CONFIG_ARCH_PROC_KCORE_TEXT In-Reply-To: <1497437035-11979-1-git-send-email-ard.biesheuvel@linaro.org> References: <1497437035-11979-1-git-send-email-ard.biesheuvel@linaro.org> Message-ID: <1497437035-11979-3-git-send-email-ard.biesheuvel@linaro.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org To avoid issues with the /proc/kcore code getting confused about the kernels block mappings in the VMALLOC region, enable the existing facility that describes the [_text, _end) interval as a separate KCORE_TEXT region, which supersedes the KCORE_VMALLOC region that it intersects with on arm64.
