From a79f248b9b309ebb5f34ca6a8fd1eb9e18db5720 Mon Sep 17 00:00:00 2001 From: David Daney Date: Thu, 19 Apr 2012 14:59:55 -0700 Subject: scripts: Add sortextable to sort the kernel's exception table. Using this build-time sort saves time booting as we don't have to burn cycles sorting the exception table.

If there are relocations on the __ex_table section, they are redundant and probably incorrect after the sort, so they are zeroed out leaving them valid and consistent.
