From bebf023d415fd8984994a596aaa83cd0a3046d0b Mon Sep 17 00:00:00 2001 From: Martin Schwidefsky Date: Wed, 13 Jan 2010 20:44:28 +0100 Subject: [S390] remove superfluous TIF_USEDFPU bit The TIF_USEDFPU bit is always 0 for s390 and it is not tested anywhere. Remove the bit. At the same time remove the calls to clear_used_math() as well. The PF_USED_MATH bit is never set for s390 either.
