Peter Anvin" , "linux-kernel@vger.kernel.org" Subject: [PATCH] x86, acpi: Remove out-of-date comment of __acpi_map_table Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 1777 Lines: 50 From: Zhang Yanfei The implementation of function __acpi_map_table() has been changed long time ago, and now it directly invokes early_ioremap() to setup the temporarily acpi table mappings. So remove its out-of-date comment.
