* are flush_tlb_*() routines, and these run after flush_cache_*()
* which performs the flushw.
*
* The SMP TLB coherency scheme we use works as follows:
*
* 1) mm->cpu_vm_mask is a bit mask of which cpus an address
* space has (potentially) executed on, this is the heuristic
* we use to avoid doing cross calls.
*
* Also, for flushing from kswapd and also for clones, we
* use cpu_vm_mask as the list of cpus to make run the TLB.
*
* 2) TLB context numbers are shared globally across all processors
* in the system, this allows us to play several games to avoid
* cross calls.
*
* One invariant is that when a cpu switches to a process, and
* that processes tsk->active_mm->cpu_vm_mask does not have the
* current cpu's bit set, that tlb context is flushed locally.
*
* If the address space is non-shared (ie. mm->count == 1) we avoid
* cross calls when we want to flush the currently running process's
* tlb state. This is done by clearing all cpu bits except the current
* processor's in current->mm->cpu_vm_mask and performing the
* flush locally only. This will force any subsequent cpus which run
* this task to flush the context from the local tlb if the process
* migrates to another cpu (again).
*
* 3) For shared address spaces (threads) and swapping we bite the
* bullet for most cases and perform the cross call (but only to
* the cpus listed in cpu_vm_mask).
*
* The performance gain from "optimizing" away the cross call for threads is
* questionable (in theory the big win for threads is the massive sharing of
* address space state across processors).
* mm->cpu_vm_mask is a bit mask of which cpus an address
* space has (potentially) executed on, this is the heuristic
* we use to limit cross calls.
