From b5dfcb09debc38582c3cb72a3c1a88b919b07f2d Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Mon, 11 Nov 2013 19:53:42 +0100 Subject: Revert "x86/UV: Add uvtrace support" This reverts commit 8eba18428ac926f436064ac281e76d36d51bd631. uv_trace() is not used by anything, nor is uv_trace_nmi_func, nor uv_trace_func. That's not how we do instrumentation code in the kernel: we add tracepoints, printk()s, etc. so that everyone not just those with magic kernel modules can debug a system. So remove this unused (and misguied) piece of code.
