5a2451f10550 ("x86/fpu: Avoid kabi change caused by struct fpu") will lead to performance degradation of libmicro pthread_create testcase. Assuming that no 3rd party driver will reach into struct fpu, replace kabi fix macro from KABI_DEPRECATE to KABI_BROKEN_REMOVE for element "union fpregs_state state" of struct fpu.
