+On a zEC12 or z13, a glibc with lock elision enabled infers from HWCAP
+that the prerequisites for lock elision are met.  Then it may use TBEGIN
+and other transactional-execution instructions which are not implemented
+by Valgrind.  Likewise, the upcoming glibc 2.23 will exploit vector
+instructions if they are advertised by HWCAP; and those are currently
+not implemented by Valgrind either.  In general, the increased use of
+ifunc may lead to more such cases in the future.
+
+This patch suppresses the advertising of those hardware features via
+HWCAP which are either not known to Valgrind or currently unsupported.
+
+Patch by Andreas Arnez (arnez@linux.vnet.ibm.com).
+Fixes BZ #353680.
