Turn off hwtrace in CPLB handlers


Linux Kernel Configuration
└─>Kernel hacking
└─>Turn off hwtrace in CPLB handlers
In linux kernel since version 2.6.24 (release Date: 2008-01-24)  
The CPLB error handler contains a lot of flow changes which can
quickly fill up the hardware trace buffer. When debugging crashes,
the hardware trace may indicate that the problem lies in kernel
space when in reality an application is buggy.

Say Y here to disable hardware tracing in some known "jumpy" pieces
of code so that the trace buffer will extend further back.
