From 6619a8fb594486363783cc4a8372e4d4ee4b913e Mon Sep 17 00:00:00 2001 From: H. Peter Anvin Date: Wed, 17 Oct 2007 18:04:37 +0200 Subject: x86: Create clflush() inline, remove hardcoded wbinvd Create an inline function for clflush(), with the proper arguments, and use it instead of hard-coding the instruction. This also removes one instance of hard-coded wbinvd, based on a patch by Bauder de Oliveira Costa. [ tglx: arch/x86 adaptation ] Cc: Andi Kleen Cc: Glauber de Oliveira Costa Signed-off-by: H.
