Subject: [PATCH 0/2] math: fix known directed rounding problems
fix the two known directed rounding bugs in current math code.
(there are still large ulp errors in j0, y0, jn, yn functions,
but all other functions should have small worst case ulp error now)
Szabolcs Nagy (2):
math: fix __rem_pio2 in non-nearest rounding modes
math: fix sinh overflows in non-nearest rounding
