x86: prepare 64-bit architecture initialization for paravirt
This patch prepares the x86_64 architecture initialization for paravirt. It requires a memory initialization step, which is done by implementing 64-bit version for machine_specific_memory_setup, and putting an ARCH_SETUP hook, for guest-dependent initialization. This last step is done akin to i386 Signed-off-by: Glauber de Oliveira Costa <gcosta@redhat.com> Signed-off-by: Steven Rostedt <rostedt@goodmis.org> Acked-by: Jeremy Fitzhardinge <jeremy@xensource.com> Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
