[PATCH 1/2] locking/atomics: Change 'fold' to 'grep'

From: Mark Rutland
Date: Mon Dec 10 2018 - 12:50:48 EST


From: Anders Roxell <anders.roxell@xxxxxxxxxx>

Some distibutions and build systems doesn't include 'fold' from
coreutils default.

.../scripts/atomic/atomic-tbl.sh: line 183: fold: command not found

Rework to use 'grep' instead of 'fold' to use a dependency that is
already used a lot in the kernel.
