From d7285c6b5c54397fdf112c2fb98ee43193173aa9 Mon Sep 17 00:00:00 2001 From: Chris Wright Date: Thu, 23 Apr 2009 10:21:38 -0700 Subject: x86: use native register access for native tlb flushing currently these are paravirtulaized, doesn't appear any callers rely on this (no pv_ops backends are using native_tlb and overriding cr3/4 access).
