SVN rev 193303 on 2009-06-02 08:02:27Z by alc
Correct a boundary case error in the management of a page's dirty bits by
shm_dotruncate() and vnode_pager_setsize(). Specifically, if the length of
a shared memory object or a file is truncated such that the length modulo
the page size is between 1 and 511, then all of the page's dirty bits were
cleared. Now, a dirty bit is cleared only if the corresponding block is
truncated in its entirety.
