From 3255aa2eb636a508fc82a73fabbb8aaf2ff23c0f Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Wed, 25 Feb 2009 08:21:52 +0100 Subject: x86, mm: pass in 'total' to __copy_from_user_*nocache() Impact: cleanup, enable future change Add a 'total bytes copied' parameter to __copy_from_user_*nocache(), and update all the callsites. The parameter is not used yet - architecture code can use it to more intelligently decide whether the copy should be cached or non-temporal.
