So, for 3.9+ kernels, this issue should be fixed. If we want to try to fix this for kernels <= 3.8, we could either: 1) Use 'do_sigaltstack' for syscall.sigaltstack, since sys_sigaltstack just seems to be a wrapper for it anyway. 2) To just get things to compile, use 'never' for syscall.sigaltstack. -- You are receiving this mail because: You are the assignee for the bug.
