Subject: RE: [ PATCH ] - Avoid slow TLB purges on SGI Altix systems
Date: Thu, 27 Oct 2005 09:01:53 -0700 [thread overview]
Message-ID: <B8E391BBE9FE384DAA4C5C003888BE6F04C8CF40@scsmsx401.amr.corp.intel.com> (raw)
- if (mm != current->active_mm) {
- /* this does happen, but perhaps it's not worth optimizing for? */
-#ifdef CONFIG_SMP
- flush_tlb_all();
-#else
- mm->context = 0;
-#endif
- return;
- }
Your patch moves this secion of code up to ia64_global_tlb_purge(),
but the new code that is added there doesn't include the UP case
where mm->context is set to zero.
