Kirill A. Shutemov d25ef8b86e ARM: 5728/1: Proper prefetch abort handling on ARMv6 and ARMv7 ... Currently, on ARMv6 and ARMv7, if an application tries to execute code (or garbage) on non-executable page it hangs. It caused by incorrect prefetch abort handling. Now every prefetch abort processes as a translation fault. To fix this we have to analyze instruction fault status register to figure out reason why we've got the abort and process it accordingly. To make IFSR different from DFSR we set bit 31 which is reserved in both IFSR and DFSR. This patch also tries to protect from future hangs on unexpected exceptions. An application will be killed if unexpected exception type was received. Signed-off-by: Kirill A.
