From 5290dc292915aaed6ae71ec3db5d4aa3285e7d51 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Thu, 3 May 2012 09:02:50 +0000 Subject: [PATCH] arm: Use generic init_task Same code. Use the generic version. The special Makefile treatment is pointless anyway as init_task.o contains only data which is handled by the linker script. So no point on being treated like head text.
