From 648616343cdbe904c585a6c12e323d3b3c72e46f Mon Sep 17 00:00:00 2001 From: Martin Schwidefsky Date: Thu, 15 Dec 2011 14:56:09 +0100 Subject: [S390] cputime: add sparse checking and cleanup Make cputime_t and cputime64_t nocast to enable sparse checking to detect incorrect use of cputime. Drop the cputime macros for simple scalar operations. The conversion macros are still needed.
