Subject: [v4 PATCH 00/13] crypto: acomp - Add virtual address and folio support

v4 adds acomp software fallback path, folio support and converts
existing legacy crypto_comp users.

This patch series adds virtual address and folio support to acomp.
This finally brings it to feature parity with the legacy crypto_comp,
which enables us to convert the existing users to acomp.

The three users are converted according to their characteristics:
ubifs uses folio+linear, hibernate uses linear only while ipcomp
uses SG only.

Only ipcomp is fully asynchronous, ubifs supports asynchronous
but will wait on it and hibernate is synchronous only.

Herbert Xu (13):
  crypto: qat - Remove dst_null support
  crypto: iaa - Remove dst_null support
  crypto: scomp - Remove support for some non-trivial SG lists
  crypto: acomp - Remove dst_free
  crypto: scomp - Add chaining and virtual address support
  crypto: acomp - Add ACOMP_REQUEST_ALLOC and acomp_request_alloc_extra
  crypto: iaa - Use acomp stack fallback
  crypto: acomp - Add async nondma fallback
  crypto: acomp - Add support for folios
  ubifs: Use crypto_acomp interface
  ubifs: Pass folios to acomp
  PM: hibernate: Use crypto_acomp interface
  xfrm: ipcomp: Use crypto_acomp interface
