Merge branch 'compat-removal'
Heiko Carstens says:
====================
Remove s390 compat support to allow for code simplification and especially
reduced test effort. To the best of our knowledge there aren't any 31 bit
binaries out in the world anymore that would matter for newer kernels or
newer distributions.
Distributions do not provide compat packages since quite some time or even
have CONFIG_COMPAT disabled.
Instead of adding deprecation warnings to config option, or adding kernel
messages, just remove the code. Deprecation warnings haven't proven to be
useful. If it turns out there is still a reason to keep the compat support
this series can be reverted at any time in the future.
====================
