[Xen-devel] [PATCH] xentrace_format supports a system that has more than 8 CPUs

["KUWAMURA Shin'ya" <kuwa@xxxxxxxxxxxxxx>]

Hi, all

I ran xentrace_format on a machine of 16 CPUs and got the following
error message:

  Traceback (most recent call last):
    File "/usr/bin/xentrace_format", line 114, in ?
      if tsc < last_tsc[cpu]:
  IndexError: list index out of range

This patch fixes this problem and remove the limit of #CPU in
xentrace_format.

Signed-off-by: KUWAMURA Shin'ya <kuwa@xxxxxxxxxxxxxx>

Thanks,
