Subject: [PATCH v4 09/14] acpi, numa: remove unneeded acpi_numa=1
Date: Mon, 18 Apr 2016 14:14:07 -0700	[thread overview]
Message-ID: <1461014052-30788-10-git-send-email-ddaney.cavm@gmail.com> (raw)
In-Reply-To: <1461014052-30788-1-git-send-email-ddaney.cavm@gmail.com>

From: Hanjun Guo <hanjun.guo@linaro.org>

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.
