From mboxrd@z Thu Jan 1 00:00:00 1970 From: guohanjun@huawei.com (Hanjun Guo) Date: Sat, 23 Jan 2016 17:39:26 +0800 Subject: [PATCH v3 11/12] acpi, numa: remove unneeded acpi_numa=1 In-Reply-To: <1453541967-3744-1-git-send-email-guohanjun@huawei.com> References: <1453541967-3744-1-git-send-email-guohanjun@huawei.com> Message-ID: <1453541967-3744-12-git-send-email-guohanjun@huawei.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org From: Hanjun Guo acpi_numa is default to 0, it's set to -1 when disable acpi numa or when a bad SRAT is parsed, and it's only consumed in srat_disabled() (compare it with 0) to continue parse the SRAT or not, so we don't need to set acpi_numa to 1 when we get a valid SRAT entry.
