From a074335a370eca6d72f2ec890e4ae22923a2aea4 Mon Sep 17 00:00:00 2001 From: "H. Peter Anvin" Date: Mon, 5 Dec 2011 22:48:49 -0800 Subject: x86, um: Mark system call tables readonly Mark the system call tables readonly, as they already are on native, and the 32-bit UM version was in the previous assembly version. The 32-bit version lost it due to copy and paste from the 64-bit version, which was missing the const.
