Merge branch 'uaccess-inline-asm-cleanup' into features

Heiko Carstens says:

===================
There are a couple of oddities within the s390 uaccess library
functions. Therefore cleanup the whole uaccess.c file.

There is no functional change, only improved readability. The output
of "objdump -Dr" was always compared before/after each patch to make
sure that the generated object file is identical, if that could be
expected. Therefore the series also includes more patches than really
required to cleanup the code.

Furthermore the kunit usercopy tests also still pass.
