alloc_heap_pages is low efficient with more CPUs
...static struct page_info *alloc_heap_pages(
unsigned int zone_lo, unsigned int zone_hi,
unsigned int node, unsigned int order, unsigned int memflags)
{
if ( pg[i].u.free.need_tlbflush )
{
/* Add in extra CPUs that need flushing because of this page. */
cpus_andnot(extra_cpus_mask, cpu_online_map, mask);
tlbflush_filter(extra_cpus_mask, pg[i].tlbflush_timestamp);
cpus_or(mask, mask, extra_cpus_mask);
}
}
1 in the first starting, most of need_tlbflush=NULL, so cost little; in the second one, most of RAM have been used
thus...

hook and architecture specific code.
- PG_state_change page flag has been replaced with architecture
