+Note; the test is known to fail on the RHEL 7.7 kernel - the patch
+fixes PT_GETREGS (which we want) but adds PTRACE_SINGLEBLOCK (which we
+don't support yet).  So, the test case was not included.  - DJ

+    S390: Sync ptrace.h with kernel. [BZ #21539]
+    
+    This patch removes PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS
+    and PTRACE_SETFPREGS as these requests does not exist on s390 kernel.
+    
+    But the kernel has support for PTRACE_SINGLEBLOCK,
+    PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA, PTRACE_POKEUSR_AREA,
+    PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE, PTRACE_DISABLE_TE and
+    PTRACE_TE_ABORT_RAND.  Thus those are defined now.
+    
+    The current kernel s390 specific ptrace.h file also defines
+    PTRACE_PEEKTEXT_AREA, PTRACE_PEEKDATA_AREA, PTRACE_POKETEXT_AREA,
+    PTRACE_POKEDATA_AREA, PTRACE_PEEK_SYSTEM_CALL, PTRACE_POKE_SYSTEM_CALL
+    and PTRACE_PROT, but those requests are not supported.
+    Thus those defines are skipped in glibc ptrace.h.
+    
+    There were old includes of ptrace.h in sysdeps/s390/fpu/fesetenv.c.
+    The ptrace feature isn't used there anymore, thus I removed the includes.
+    
+    Before this patch, <glibc>/sysdeps/unix/sysv/linux/s390/sys/ptrace.h
+    uses ptrace-request 12 for PTRACE_GETREGS,
+    but <kernel>/include/uapi/linux/ptrace.h uses 12 for PTRACE_SINGLEBLOCK.
+    
+    The s390 kernel has never had support for PTRACE_GETREGS!
+    Thus glibc ptrace.h is adjusted to match kernel ptrace.h.
+    
+    The new s390 specific test ensures, that PTRACE_SINGLEBLOCK defined
+    in glibc works as expected.  If the kernel would interpret it as
+    PTRACE_GETREGS, then the testcase will not make any progress
+    and will time out.
+    
+    ChangeLog:
+    
+    	[BZ #21539]
+    	* NEWS: Mention s390 ptrace request changes.
+    	* sysdeps/unix/sysv/linux/s390/sys/ptrace.h
+    	(PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS,
+    	PTRACE_SETFPREGS): Remove enum constant.
+    	(PT_GETREGS, PT_SETREGS, PT_GETFPREGS, T_SETFPREGS):
+    	Remove defines.
+    	(PTRACE_SINGLEBLOCK): New enum constant.
+    	(PT_STEPBLOCK): New define.
+    	(PTRACE_PEEKUSR_AREA, PTRACE_POKEUSR_AREA,
+    	PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE, PTRACE_DISABLE_TE,
+    	PTRACE_TE_ABORT_RAND): New enum constant and define.
+    	* sysdeps/s390/fpu/fesetenv.c: Remove ptrace.h includes.
+    	* sysdeps/unix/sysv/linux/s390/tst-ptrace-singleblock.c:
+    	New file.
+    	* sysdeps/unix/sysv/linux/s390/Makefile: Add test.
