The software reserved portion of the fxsave frame in the signal frame is copied from structures which have been set up at boot time. With dynamically enabled features the content of these structures is no longer correct because the xfeatures and size can be different per task. Calculate the software reserved portion at runtime and fill in the xfeatures and size values from the tasks active fpstate. Signed-off-by: Chang S.
