From 168e47f2a6581fdbc5bb1845aeca1e50e2bc5c4b Mon Sep 17 00:00:00 2001 From: Laura Abbott Date: Wed, 25 Feb 2015 14:14:57 -0800 Subject: [PATCH] kernel/module.c: Update debug alignment after symtable generation When CONFIG_DEBUG_SET_MODULE_RONX is enabled, the sizes of module sections are aligned up so appropriate permissions can be applied. Adjusting for the symbol table may cause them to become unaligned. Make sure to re-align the sizes afterward.
