mctp i3c: handle NULL header address
daddr can be NULL if there is no neighbour table entry present, in that case the tx packet should be dropped. saddr will usually be set by MCTP core, but check for NULL in case a packet is transmitted by a different protocol.

Maybe in the future we want a registration interface? At least for now, it can be easily handled using the two page types that actually support page migration. The remaining usage of page->mapping is to flag such pages as actually being movable (having movable_ops), which we will change next.

To achieve that, introduce a couple of helper functions: - zpdesc_lock() - zpdesc_unlock() - zpdesc_trylock() - zpdesc_wait_locked() - zpdesc_get() - zpdesc_put() Here we use the folio version of functions for 2 reasons. First, zswap.zpool currently only uses order-0 pages and using folio could save some compound_head checks. Second, folio_put could bypass devmap checking that we don't need. BTW, thanks Intel LKP found a build warning on the patch.

This patch series introduces a new memory descriptor for zswap.zpool that currently overlaps with struct page for now. This is part of the effort to reduce the size of struct page and to enable dynamic allocation of memory descriptors [1]. This series does not bloat anything for zsmalloc and no functional change is intended (except for using zpdesc and folios). In the near future, the removal of page->index from struct page [2] will be addressed and the project also depends on this patch series. Thanks to everyone got involved in this series, especially, Alex who's been pushing it forward this year.

We removed the comment about PG_owner_priv_1 since it is no longer used after commit a41ec880aa7b ("zsmalloc: move huge compressed obj from page to zspage").
