[PATCH] linux/types.h: remove prehistoric ifndefs

From: Rasmus Villemoes
Date: Thu Jun 11 2015 - 05:44:35 EST


Whatever the "historical reasons" were back around 1996 when this
comment was added,

git grep -E '\b_(S?SIZE|TIME|CLOCK|PTRDIFF|CADDR)_T\b'

seems to say that they are no longer relevant. Relieve the
preprocessor from a little work.
