Subject: [PATCH v8 04/13] arm64/acpi: Create arch specific cpu to acpi id helper
Date: Wed, 25 Apr 2018 18:31:12 -0500	[thread overview]
Message-ID: <20180425233121.13270-5-jeremy.linton@arm.com> (raw)
In-Reply-To: <20180425233121.13270-1-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.
