This patchset provides page mapping via the page table.
On some archs, most notably ARM, this method has been
demonstrated to be faster than copying.
The logic controlling the method selection (copy vs page table)
is controlled by the definition of USE_PGTABLE_MAPPING which
is/can be defined for any arch that performs better with page
table mapping.

Because we use per-cpu mapping areas shared among the
pools/users, we can't allow mapping in interrupt context
because it can corrupt another users mappings.

firstpage already has precedent and meaning the first page
of a zspage. In the case of the copy mapping functions,
it is the first of a pair of pages needing to be mapped.
This patch just renames the firstpage argument to "page" to
avoid confusion.

The current value for the maximum receive buffer size is 30720, which is
too large. For long-running systems, memory fragmentation may make it
difficult to obtain the buffers of O(2) needed for aggregation. Buffers
of O(3) are even worse, particularly when not needed. The new size is set
to 9100, which will allow aggregation.

The reclaim_buffers callback has already been removed by Daniel Vetter
<daniel.vetter@ffwll.ch> with his patch "drm: kill reclaim_buffers callback"
(b0071efe82). As a result the kernel compilation fails with omapdrm support
and so the callback for reclaim_buffers is being removed from omapdrm.
