Hi Anju ,
The above test kernel add issue while setting up, so rebuilt the
upstream kernel with the patches mentioned above.
=> Perf fuzzer works fine and issue is not seen.
=> Thread IMC also works fine.

'{emulation-faults, thread_imc/CPM_CCYC/, thread_imc/CPM_CS_32MHZ_CYC/,
thread_imc/CPM_CS_BRU_CMPL_KERNEL/}' yes > /dev/null
