Kernel: Allow release of a specific amount of of clean pages

Browse source 
Previously, we could only release *all* clean pages.
This patch makes it possible to release a specific amount of clean
pages. If the attempted number of pages to release is more than the
amount of clean pages, all clean pages will be released.
