Are you sure this is coming from the LTTng patches? Which actual
patch makes this change?

Thanks kumar,
I've got the patch out which fixes the issues. But now.. seems there is some
generic issue in PPC440 targets, I am observing that
*remap_file_pages01* and *remap_file_pages02 *test cases from LTP are
failing since *Linux-2.6.24* kernel to *Linux-2.6.30*. If you can give some
pointers that would be greatly appreciated ! Or if you have results for this
on any PPC44x would be helpful.
Arch : PowerPC
Target : Xilinx PowerPC440 virtex5
I've tried to test the cause for this but found that kernel throws error
message of "segmentation fault".
Thanks in Advance.
