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.
