# commit 7ea8e3867bf70381f71e54f1479b492ba84527fa
# Author: Mahesh Salgaonkar <mahesh@linux.vnet.ibm.com>

#     Disable kcov for slb routines.
#     
#     The kcov instrumentation inside SLB routines causes duplicate SLB entries
#     to be added resulting into SLB multihit machine checks.
#     Disable kcov instrumentation on slb.o
