I want to find a way to get all those PageReserved tests out of
there, because they are very expensive.  But now is not the
time.

Make sure that the VC tty pointer is cleared when the tty is free'd.

bit of cleaning later.

a bit later

Note: I've also fixed several obvious "forgot to update" problems (changed
prototype of blk_init_queue(), etc.) but I hadn't touched the DMA-mapping
stuff, so it still doesn't work with 2.5; moreover, it misses a lot of fixes
done in 2.4, but that's fun for Alan - he's the maintainer

Well I didn't test that very well.  __page_cache_release() is doing a
__free_page() on a zero-ref page, so __free_pages() sends the refcount
negative and doesn't free it.  With patch #8, page_cache_release()
almost never frees pages, but it must have been leaking a little bit.
Lucky it showed up.

This fixes it, and also adds a missing PageReserved test in put_page().
Which makes put_page() identical to page_cache_release(), but there are
header file woes.  I'll fix that up later.

This trivial patch reorders the unlocking in rq_unlock()... I was
tired of getting stack dumps in my messages file.

isn't ready for it (either during early boot, or at shutdown)
