From: Mark Rutland <[email protected]> As with x86, mark the sys_call_table const such that it will be placed in the .rodata section. This will cause attempts to modify the table (accidental or deliberate) to fail when strict page permissions are in place. In the absence of strict page permissions, there should be no functional change.
