// *! TITLE : p9_l2err_extract.H
// *! DESCRIPTION : Parse and extract error information from L2 trace array (FAPI)
// *!
// *! OWNER NAME : Chen Qian Email: qianqc@cn.ibm.com
// *!
// *! ADDITIONAL COMMENTS :
// *!
// *! Parses the contents of the L2_T0 trace array for L2 error data.
// *! Will look for occurances of an L2 CE or UE and capture associated data.
// *!
// *! Assume that the L2 trace array is set up to capture CEs/UEs, and
// *! that it is NOT running in banked mode. Also trace must have been set to
// *! stop on error.
// *|
// *! NOTE: Trace entries must be provided within data buffer from oldest->youngest entry.
// *!
// *! NOTE: This procedure only looks for the oldest error in the trace array. Other
// *! errors can be present in the first or second beat of data, or for datawords
// *! greater than the one with the first error.
