From 57da8b960b9a25646a8ddb5a9c1d0b5978e69bec Mon Sep 17 00:00:00 2001 From: Jan Beulich Date: Wed, 9 May 2012 08:47:37 +0100 Subject: x86: Avoid double stack traces with show_regs() What was called show_registers() so far already showed a stack trace for kernel faults, and kernel_stack_pointer() isn't even valid to be used for faults from user mode, hence it was pointless for show_regs() to call show_trace() after show_registers(). Simply rename show_registers() to show_regs() and eliminate the old definition.
