SPARC has also suffered from this change:

sparc$ ./strace -e, true
syscall: unknown syscall trap 1a80000d f7aceb48
+++ exited with 0 +++

Not as fatal as on ARM, but enough to trigger bexecve.test failure.

BTW, this "resuming interrupted system call" feature is broken on SPARC:

$ sleep 2 & sleep 1; ./strace -p $!
[1] 24450
Process 24450 attached
syscall: unknown syscall trap 1a800004 f7ebea10
syscall_516(0, 0x14980, 0x117e0, 0x1, 0x2, 0xffaef328) = 0
close(1)                                = 0
close(2)                                = 0
exit_group(0)                           = ?
+++ exited with 0 +++
[1]+  Done                    sleep 2

ERESTART_RESTARTBLOCK is 516; what a coincidence! :)
