Subject: [PATCH v5 1/9] arm64/acpi: Create arch specific cpu to acpi id helper
Date: Fri, 1 Dec 2017 16:23:22 -0600 [thread overview]
Message-ID: <20171201222330.18863-2-jeremy.linton@arm.com> (raw)
In-Reply-To: <20171201222330.18863-1-jeremy.linton@arm.com>
Its helpful to be able to lookup the acpi_processor_id associated
with a logical cpu. Provide an arm64 helper to do this.
