Subject: [PATCH v6 04/12] arm64/acpi: Create arch specific cpu to acpi id helper
Date: Fri, 12 Jan 2018 18:59:12 -0600 [thread overview]
Message-ID: <20180113005920.28658-5-jeremy.linton@arm.com> (raw)
In-Reply-To: <20180113005920.28658-1-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.
