Rip out most of the ptrace code for AVR32 and replace it with the
much nicer utrace stuff. It builds in all possible combinations of
CONFIG_UTRACE and CONFIG_PTRACE, and it seems to work as far as I've

When we are out of memory of a suitable size we enter reclaim.
The current reclaim algorithm targets pages in LRU order, which
is great for fairness at order-0 but highly unsuitable if you desire
pages at higher orders. To get pages of higher order we must shoot
down a very high proportion of
As pointed out by Christop Lameter it should not be possible for a
page to change its active/inactive state without taking the lru_lock.
