[merged] page-allocator-clean-up-functions-related-to-pages_min.patch removed from -mm tree

[akpm]

The patch titled
     page-allocator: clean up functions related to pages_min
has been removed from the -mm tree.  Its filename was
     page-allocator-clean-up-functions-related-to-pages_min.patch

This patch was dropped because it was merged into mainline or a subsystem tree

The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/

------------------------------------------------------
Subject: page-allocator: clean up functions related to pages_min
From: Minchan Kim <minchan.kim@gmail.com>

Change the names of two functions. It doesn't affect behavior. 

Presently, setup_per_zone_pages_min() changes low, high of zone as well as
min.  So a better name is setup_per_zone_wmarks().  That's because Mel
changed zone->pages_[hig/low/min] to zone->watermark array in "page
allocator: replace the watermark-related union in struct zone with a
watermark[] array".

 * setup_per_zone_pages_min => setup_per_zone_wmarks

Of course, we have to change init_per_zone_pages_min, too.  There are not
pages_min any more.  

 * init_per_zone_pages_min => init_per_zone_wmark_min
