From d1ba71f7645696020864fe3cea3049befbe50408 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Wed, 27 Oct 2010 16:58:22 +0900 Subject: [PATCH] sh64: oprofile: Fix up kernel stack pointer size mismatch. For the backtrace code its assumed that the stack pointer is 32-bits, which is not the case with the sh64 registers. Use the shared kernel_stack_pointer() helper to get at the actual register, which already takes care of the necessary typecasting.
