[v5,00/14] crypto: acomp - Add virtual address and folio support

Message

v5 removes the incompressible warnings in ubifs, removes more dead
code from qat, and replaces crypto_has_comp with crypto_has_acomp
in hibernate and ipcomp.

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 (14):
  xfrm: ipcomp: Call pskb_may_pull in ipcomp_input
  crypto: scomp - Remove support for some non-trivial SG lists
  crypto: iaa - Remove dst_null support
  crypto: qat - Remove dst_null support
  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
  xfrm: ipcomp: Use crypto_acomp interface
  PM: hibernate: Use crypto_acomp interface
  ubifs: Use crypto_acomp interface
  ubifs: Pass folios to acomp
