This patchset makes use of the new bulk page allocation interface to
reduce the overhead of allocating large numbers of pages in a
loop.
The first two patches are refactoring buffer memory allocation and
converting the uncached buffer path to use the same page allocation
path, followed by converting the page allocation path to use bulk
allocation.
The rest of the patches are then consolidation of the page
allocation and freeing code to simplify the code and remove a chunk
of unnecessary abstraction. This is largely based on a series of
changes made by Christoph Hellwig.
