From ec81ad4eca9736bb73d4458fb7d8a5ccaf3e908e Mon Sep 17 00:00:00 2001 From: Hanjun Guo <hanjun.guo@linaro.org> Date: Fri, 27 Mar 2015 12:14:35 +0000 Subject: [PATCH] ARM64 / ACPI: Ignore the return error value of acpi_map_gic_cpu_interface() MADT scanning will stop when it gets an error from the handler, acpi_map_gic_cpu_interface(), on arm64. However, we need to find all of the enabled CPUs so that SMP initialization can work properly. So, if an error occurs in this case, ignore it for now so that we can find all of the enabled CPUs.
