Use kernel standard bit spin-lock instead of custom mess. Even, it has
a bug which doesn't disable preemption. The reason we don't have any
problem is that we have used it during preemption disable section
by class->lock spinlock. So no need to go to stable.

Procedure of page migration is as follows:
First of all, it should isolate a page from LRU and try to
migrate the page. If it is successful, it releases the page
for freeing. Otherwise, it should put the page back to LRU

For LRU pages, we have used putback_lru_page for both freeing

We have allowed migration for only LRU pages until now and it was

Currently, putback_zspage does free zspage under class->lock

locking scheme for new zspage migration.
So, this patch is to separate free_zspage from putback_zspage
and free zspage out of class->lock which is preparation for

Zsmalloc is ready for page migration so zram can use __GFP_MOVABLE
from now on.
I did test to see how it helps to make higher order pages.
Test scenario is as follows.

for i in `seq 1 8`;

dd if=/dev/vda1 of=mnt/test$i.txt bs=128M
For page migration, we need to create page chain of zspage dynamically
so this patch factors it out from alloc_zspage.

This patch introduces run-time migration feature for zspage.
For migration, VM uses page.lru field so it would be better to not use
page.next field for own purpose. For that, firstly, we can get first
object offset of the page via runtime calculation instead of
page->index so we can use page->inde
Zsmalloc stores first free object's position into
freeobj in each zspage. If we change it with index from first_page
instead of position, it makes page migration simple because we
don't need to correct other entries for linked list if a page is
migrated out.

We have squeezed meta data of zspage into first page's descriptor.
So, to get meta data from subpage, we should get first page first

can be raced with first page migrat
Recently, I got many reports about perfermance degradation in embedded
