From 6763781e70cc782060611eef91aa27166e418992 Mon Sep 17 00:00:00 2001 From: Mark Rutland Date: Mon, 13 Jun 2016 17:57:02 +0100 Subject: [PATCH] UPSTREAM: arm64: mm: mark fault_info table const Unlike the debug_fault_info table, we never intentionally alter the fault_info table at runtime, and all derived pointers are treated as const currently. Make the table const so that it can be placed in .rodata and protected from unintentional writes, as we do for the syscall tables.
