Subject: [PATCH v4 3/9] arm64/acpi: Create arch specific cpu to acpi id helper
Date: Thu,  9 Nov 2017 15:03:05 -0600	[thread overview]
Message-ID: <20171109210311.25655-4-jeremy.linton@arm.com> (raw)
In-Reply-To: <20171109210311.25655-1-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.
