+ARMv7 LPAE: IFSR doesn't have the LPAE bit in case of BKPT
+
+When a user application triggers a 'bkpt' instruction while LPAE is used, the bit [9] of IFSR is not correctly set during the prefetch abort exception.
+
+You'll find attached a minimal example to reproduce the issue (just run 'make all').
+The output I get is:
+
+supervisor
+user
+prefetch
+short-descriptor
+
+The last entry should read 'long-descriptor'.
