Ok, I eyeballed it some more, and tested both the OFFSTACK and ONSTACK
case, and decided that I had better commit it now rather than wait any
later since I'll do the -rc1 later today, and will be on an airplane
most of tomorrow.
The exact placement of the cpu_vm_mask_var is up for grabs. For
example, I started thinking that it might be better to put it *after*
the mm_context_t, since for the non-OFFSTACK case it's generally
touched at the beginning rather than the end.
And the actual change to make the mm_cachep kmem_cache_create() use a
variable-sized allocation for the OFFSTACK case is similarly left as
an exercise for the the reader. So effectively, this reverts a lot of
de03c72cfce5, but does so in a way that should make very it easy to
get back to where KOSAKI was aiming for.
Whatever. I was hoping to get comments on it, but I think I need to
rather push it out to get tested and public than wait any longer. The
patch *looks* fine, tests ok on my machine, and removes more lines
than it adds despite the new big comment.
