[frank.heimes at canonical.com]

Buglink: https://bugs.launchpad.net/bugs/1830208

The following patches add several improvements for s390x hardware compression via zlib.

Frank Heimes (1):
  Ubuntu: [Config] Introducing s390x specific kernel config option
    CONFIG_ZLIB_DFLTCC

Mikhail Zaslonko (6):
  lib/zlib: add s390 hardware support for kernel zlib_deflate
  s390/boot: rename HEAP_SIZE due to name collision
  lib/zlib: add s390 hardware support for kernel zlib_inflate
  s390/boot: add dfltcc= kernel command line parameter
  lib/zlib: add zlib_deflate_dfltcc_enabled() function
  btrfs: use larger zlib buffer for s390 hardware compression
