--------------------------------

5a2451f1 ("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.
