lguest: Fix guest crash when CONFIG_X86_USE_3DNOW=y
One of the very first things lguest_init() does is a memcpy. On Athlon/Duron/K7 or CyrixIII/VIA-C3 or Geode GX/LX, this tries to use MMX. memcpy -> _mmx_memcpy -> kernel_fpu_begin -> clts -> paravirt_ops.clts But we haven't set paravirt_ops.clts yet, so we do the native version and crash. The simplest solution is to use __memcpy. Thanks to Michael Rasenberger for the bug report.
