Currently, hugepaged_mutex is used really complexly and hard to understand,
actually, it is just used to serialize start_khugepaged and khugepaged for
these reasons:
- khugepaged_thread is shared between them
- the thp disable path (echo never transparent_hugepage/enabled) is
nonblocking, so we
Now, khugepaged creation and cancel are completely serial under the
protection of khugepaged_mutex, it is impossible that many khugepaged
entities are running

If NUMA is disabled, hpage is used as page pre-alloc, so there are
two cases for hpage:
- it is !NULL, means the page is not consumed otherwise,
- the page has been consumed
If NUMA is enabled, hpage is just used as alloc-fail indicator which
is not a real page, NULL means not fail triggered.
There are two pre-alloc operations in these two function, the different is:
- it allows to sleep if page alloc fail in khugepaged_loop
- it exits immediately if page alloc fail in khugepaged_do_scan
Actually, in khugepaged_do_scan, we can allow the pre-alloc to sleep on the
first failure, then
If NUMA is enabled, we can release the page in the page pre-alloc operation,
then the CONFIG_NUMA dependent code can be reduced
