Axel Dörfler e0e9a3e69f * We now support the global page feature of x86 processors that prevents
kernel TLBs from being flushed on context switch.
* new arch_cpu_user_TLB_invalidate() that now does what arch_cpu_global_TLB_invalidate()
  did before.
* arch_cpu_global_TLB_invalidate() will now flush all TLBs, even those from the
  kernel.
* some cleanups.
