Ingo Molnar 9ba6b79102 x86/fpu: Optimize fpu__activate_fpstate_read() ... fpu__activate_fpstate_read() is used before FPU registers are read from the fpstate by ptrace and core dumping. It's not necessary to unlazy non-current child tasks in this case, since the reading of registers is non-destructive.
