valgrind: backport rseq work-around
Using glibc-2.35-alpha, valgrind ptests mostly all fail with the error: WARNING: unhandled amd64-linux syscall: 334 You may be able to write your own handler. With this patch applied qemux86-64 ptest results were: TOTAL: 728 PASSED: 709 FAILED: 0 SKIPPED: 19 This patch implements the Linux rseq syscall as ENOSYS while a proper fix is being worked on as desribed in the patch commit log.

4Subject: [PATCH] Implement linux rseq syscall as ENOSYS
5
6This implements rseq for amd64, arm, arm64, ppc32, ppc64,
7s390x and x86 linux as ENOSYS (without warning).
8
9glibc will start using rseq to accelerate sched_getcpu, if
10available. This would cause a warning from valgrind every
11time a new thread is started.
12
13Real rseq (restartable sequences) support is pretty hard, so
14for now just explicitly return ENOSYS (just like we do for clone3).
15
16Upstream-Status: Backport [ 1024237358f01009fe233cb1294f3b8211304eaa ]
