Subject: arm64: make sys_call_table const

From: Mark Rutland <[email protected]>

commit c623b33b4e9599c6ac5076f7db7369eb9869aa04 upstream.

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.
