The driver porting series this week contains two articles having to do with
memory management; one looks at supporting the mmap() system call
(mapping kernel memory into user space), and the other at
get_user_pages() (mapping user space pages into the kernel). In
addition, a couple of older articles (on workqueues and the
BIO structure) have been updated to keep them current with recent
kernels. As always, the full set of articles can be found on this page.
