From c8fe4609827aedc9c4b45de80e7cdc8ccfa8541b Mon Sep 17 00:00:00 2001 From: Josh Poimboeuf Date: Fri, 16 Sep 2016 14:18:17 -0500 Subject: x86/dumpstack: Remove dump_trace() and related callbacks All previous users of dump_trace() have been converted to use the new unwind interfaces, so we can remove it and the related print_context_stack() and print_context_stack_bp() callback functions.
