fpu__prepare_read | This function must be called before we read a task's fpstate |
get_xsave_field_ptr | This wraps up the common operations that need to occur when retrieving* data from xsave state. It first ensures that the current task was* using the FPU and retrieves the data in to a buffer. It then calculates |
math_error | Note that we play around with the 'TS' bit in an attempt to get* the correct behaviour even in the presence of the asynchronous* IRQ13 behaviour |
