patch #1 add a flag to zpool, then zswap used to determine if zpool

patch #2 set flag sleep_mapped to true indicates that zbud/z3fold can
sleep in atomic context. zsmalloc didin't support sleep in atomic
context,
so not set that flag to true.

Haven't been able to actually test these yet, but looks good to me so
far, so
I have tested that this patch works well，it's better to double check
by you or someone else.
Is there anyone else testing this patch?
Can I send an official patch out?

Please wait a bit for Mike, Sebastian or me to actually test this.
Also, keep them CC'd explicitly if you are to come up with a new
version for some reason.
Best regards,
Vitaly
