From c5fc472171ec4f96d06d1ac039d88f9b89bb95db Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Fri, 20 May 2011 01:22:14 +0200 Subject: core_kernel_data(): Fix architectures that do not define _sdata Some architectures such as Alpha do not define _sdata but _data: kernel/built-in.o: In function `core_kernel_data': kernel/extable.c:77: undefined reference to `_sdata' So expand the scope of the data range to the text addresses too, this might be more correct anyway because this way we can cover readonly variables as well.
