Eric W. Biederman bce5c4c303 signal/ia64: Use the force_sig(SIGSEGV,...) in ia64_rt_sigreturn ... [ Upstream commit b92adb74ad ] The ia64 handling of failure to return from a signal frame has been trying to set overlapping fields in struct siginfo since 2.3.43. The si_code corresponds to the fields that were stomped (not the field that is actually written), so I can not imagine a piece of userspace code making sense of the signal frame if it looks closely. In practice failure to return from a signal frame is a rare event that almost never happens. Someone using an alternate signal stack to recover and looking in detail is even more rare. So I presume no one has ever noticed and reported this ia64 nonsense. Sort this out by causing ia64 to use force_sig(SIGSEGV) like other architectures.
