Subject: [PATCH v7 4/9] arm64: Rename the common MADT parse routine
Date: Tue, 23 Aug 2016 15:47:55 -0500 [thread overview]
Message-ID: <1471985280-2243-5-git-send-email-jeremy.linton@arm.com> (raw)
In-Reply-To: <1471985280-2243-1-git-send-email-jeremy.linton@arm.com>
The MADT parser in smp.c is now being used to parse
out NUMA, PMU and ACPI parking protocol information as
well as the GIC information for which it was originally
created. Rename it to avoid a misleading name.
