Heh, I was about to complain that you #ifdef'd out my lovely INVLPG tunable. But I guess on UP you just get flush_tlb_mm_range() from:
static inline void flush_tlb_mm_range(struct mm_struct *mm,
unsigned long start, unsigned long end, unsigned long vmflag)
{
if (mm == current->active_mm)
__flush_tlb_up();
}which doesn't even do INVLPG. How sad. Poor UP. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org. For more info on Linux MM, see: http://www.linux-mm.org/ . Don't email: <a href=mailto:"dont@kvack.org"> email@kvack.org </a>
