From d8dab00de9b767eaa11496a0eedf4798fc225803 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Thu, 28 Apr 2016 09:56:37 +0100 Subject: io-mapping: Specify mapping size for io_mapping_map_wc() The ioremap() hidden behind the io_mapping_map_wc() convenience helper can be used for remapping multiple pages. Extend the helper so that future callers can use it for larger ranges.
