Sorry, it looks there is no problem with your newest set :(
This was problem of my tree...

Sigh, I should be more carefull.
my note is attached.

Sorry,
-- Kame

== Note ==

I replaced si_meminfo() like following
==
#ifdef CONFIG_HIGHMEM
        val->totalhigh = nr_total_zonetype_pages(ZONE_HIGHMEM);
        val->freehigh = nr_free_zonetype_pages(ZONE_HIGHMEM);
#else
==
If ZONE_HIGHMEM has no pages, val->totalhigh is 0 and mempool for bounce buffer
is not initialized.

But, now
==
#ifdef CONFIG_HIGHMEM
        val->totalhigh = totalhigh_pages;
        val->freehigh = nr_free_highpages();
#else
==

totalhigh_pages is defined by highstart_pfn and highend_pfn.
By Zone_EasyRclm, totalhigh_pages is not affected.
mempool for bounce buffer is properly initialized....
