I think PG_highmem flag is removed just because its not needed
(CMIIW), as you can get the pfn from page by using macro " page_to_pfn
" and then from pfn you can easily get whether its of highmemory or
not.

You can also use macro " PageHighMem "
(http://lxr.linux.no/source/include/linux/page-flags.h?v=2.6.18#L159)
for verifying that whether the page is of highmem or lowmem
region/zone

I hope this helps !
