H A Dfpsimd.c59 * As an optimization, we use the thread_info flag TIF_FOREIGN_FPSTATE to
68 * variable points to the task's fpsimd_state, the TIF_FOREIGN_FPSTATE flag is
71 * - the task returns to userland; if TIF_FOREIGN_FPSTATE is set, the task's
75 * TIF_FOREIGN_FPSTATE flag is cleared;
78 * TIF_FOREIGN_FPSTATE flag will still be cleared, so no FPSIMD state is
84 * and sets the TIF_FOREIGN_FPSTATE flag;
87 * returned from the 2nd syscall yet, TIF_FOREIGN_FPSTATE is still set so
