+Subject: [PATCH] valgrind: Implement linux rseq syscall as ENOSYS
+
+This implements rseq for amd64, arm, arm64, ppc32, ppc64,
+s390x and x86 linux as ENOSYS (without warning).
+
+glibc will start using rseq to accelerate sched_getcpu, if
+available. This would cause a warning from valgrind every
+time a new thread is started.
+
+Real rseq (restartable sequences) support is pretty hard, so
+for now just explicitly return ENOSYS (just like we do for clone3).
