Subject: [PATCH 0/3] fp_barrier improvements
fp_barrier does not need to drop excess precision, so the type is
changed accordingly.
i386 fp_barrier is now "more efficient" than in the previous patch.
at least the first two patches shoud improve things on x86.
Szabolcs Nagy (3):
math: keep excess precision in fp_barrier
x86: optimize fp_arch.h
math: use fp_force_eval and fp_barrier in fma
