x86: cpa: move flush to cpa
The set_memory_* and set_pages_* family of API's currently requires the callers to do a global tlb flush after the function call; forgetting this is a very nasty deathtrap. This patch moves the global tlb flush into each of the callers Signed-off-by: Arjan van de Ven <arjan@linux.intel.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
