+Subject: [PATCH 2/2] [libquadmath] Enable libquadmath on kunpeng
+
+This enable libquadmath on kunpeng platform to convenient
+users that migrating from x86 platform. libquadmath uses "__float128"
+as quad precision floating point type and with math functions with "q"
+suffix like "cosq". For those who do not need to adapt to x86 platform,
+you can use "long double" as quad precision floating point type and math
+functions with "l" suffix like "cosl" in libm for quad precision math.
