From 8bfcb3960fde049b863266dab8c3617bb5a541aa Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Mon, 18 Aug 2008 12:33:20 +0200 Subject: x86: make movsl_mask definition non-CPU specific movsl_mask is currently defined in arch/x86/kernel/cpu/intel.c, which contains code specific to Intel CPUs. However, movsl_mask is used in the non-CPU specific code in arch/x86/lib/usercopy_32.c, which breaks the compilation when support for Intel CPUs is compiled out. This patch solves this problem by moving movsl_mask's definition close to its users in arch/x86/lib/usercopy_32.c.
