NOMMU: Revert 'nommu: get_user_pages(): pin last page on non-page-aligned start'
Revert the following patch: commit c08c6e1f Author: Steven J. Magnani <steve@digidescorp.com> Date: Fri Mar 5 13:42:24 2010 -0800 nommu: get_user_pages(): pin last page on non-page-aligned start As it assumes that the mappings begin at the start of pages - something that isn't necessarily true on NOMMU systems. On NOMMU systems, it is possible for a mapping to only occupy part of the page, and not necessarily touch either end of it; in fact it's also possible for multiple non-overlapping mappings to coexist on one page (consider direct mappings of ROMFS files, for example).
