mm: meminit: finish initialisation of struct pages before basic setup ...
Waiman Long reported that 24TB machines hit OOM during basic setup when
struct page initialisation was deferred. One approach is to initialise
memory on demand but it interferes with page allocator paths. This patch
creates dedicated threads to initialise memory before basic setup. It
then blocks on a rw_semaphore until completion as a wait_queue and counter
is overkill. This may be slower to boot but it's simplier overall and
also gets rid of a section mangling which existed so kswapd could do the
initialisation.
[akpm@linux-foundation.org: include rwsem.h, use DECLARE_RWSEM, fix comment, remove unneeded cast]
