Sven Schnelle f99450d919 s390/ipl: add missing intersection check to ipl_report handling ... commit a52e5cdbe8 upstream. The code which handles the ipl report is searching for a free location in memory where it could copy the component and certificate entries to. It checks for intersection between the sections required for the kernel and the component/certificate data area, but fails to check whether the data structures linking these data areas together intersect. This might cause the iplreport copy code to overwrite the iplreport itself. Fix this by adding two addtional intersection checks.
