-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'.
