powerpc/xmon: Disable tracing when entering xmon
If tracing is enabled and you get into xmon, the tracing buffer continues to be updated, causing possible loss of data and unnecessary tracing information coming from xmon functions. This patch simple disables tracing when entering xmon, and re-enables it if the kernel is resumed (with 'x'). Signed-off-by: Breno Leitao <leitao@debian.org> Acked-by: Naveen N.
